With the London Show now so close you can almost taste it – okay, I might be confusing the show with my snack – another software update has been announced by R-Comp, with immediate availability via !Store, and the option to buy at the show. This time the update is to PhotoDesk: We are pleased to announce that version 3.25 of PhotoDesk is now available to download for existing users via !Store. Following on from 3.24’s colossal number of changes, 3.25 is a much smaller affair, correcting a few things…

October 2025 Rougol report - RISCOSbits show plans

The October 2025 talk featured RISCOSbits supremo Andy Marks giving us a bit of a preview of their stall for Saturday's Show.

RISCOSbits at London 2025

We are pleased to announce that RISCOSbits will be exhibiting at the RISC OS London Show on Saturday, 25th October 2025. As a continuation of our commitment to providing high-quality, great value and innovative RISC OS systems, we’re bringing along a full range of new and improved products for users of all levels—from casual tinkerers to serious power users.

You’ll be able to get hands-on with our most advanced systems to date, including the blazingly fast FIRE systems with capacity for up to four full speed SATA SSDs (potentially 8TB of RISC OS format storage!), our sleek and compact VENOM, eNVY.Me and PiRO Qube NVMe machines.

You’ll also be able to get your hands on one of our new FAST NVMe XL systems, upgraded to 8GB of useable RAM! Good luck trying to use all that!

The DIY Range

We’re also excited to show off our DIY product range – a collection of hands-on kits that let you build your very own RISC OS computer. Whether you’re a seasoned hardware builder or just fancy getting under the hood, there’s something here for you.

Our entry-level system offers a compact 85mm x 110mm design, powered by a 2GHz CPU and 2GB RAM, with 128GB NVMe storage and a 32GB SD card to run RISC OS from. It’s simple, snappy, and just £119 – a great way to get started.

For those who want a little more flexibility, our mid-range kit expands to a 140mm x 120mm footprint and includes a more versatile selection of ports, 32GB of eMMC storage, 128GB of NVMe storage and USB-C and barrel jack power options – ideal for more advanced projects, priced at £179.

At the top end of the range is our DIY powerhouse system, featuring a 2.2GHz CPU, 4GB RAM, 32GB eMMC, a 256GB NVMe drive, and a custom designed wooden case that you can finish and personalise yourself. It’s the ideal choice for users who want customisability without sacrificing power or style, available for £199.

All kits come with pre-configured software, essential components, clear instructions, and zero soldering required. Just add your own screwdriver – and maybe a cup of tea!

For more details, see our new website at www.riscosbits.co.uk

Showcases at RISC OS London

We’ll also be lifting the lid on two exciting new developments currently in the works. First up is a brand new dual-OS computer system, mini.BOB. This little beast synergises the best hardware elements of Linux and RISC OS into one seriously powerful unit, all within a tidy, ultra-small footprint case. If you’ve ever dreamed of a seamless crossover between two platforms in a compact and efficient package, this might just be it.

We’ll be demonstrating the results of our ongoing work in enhancing NVMe functionality across the RISC OS platform. Rather than just chasing numbers, we’ve been focusing on real-world usability and integration – from more reliable file handling and faster boot times to improved support for large storage volumes and smoother performance under pressure. At the show, you’ll be able to see how NVMe, when properly harnessed, makes RISC OS feel more modern, stable, and capable than ever before.

We’ll have our custom wood panelled ITX cases available to take away. In either 5 litre or 8 litre capacity, these beautiful little cases make your otherwise anonymous systems really stand out. Designed as a DIY kit, they come as both a fully matt acrylic case or one with wooden front and top panels, also adding a two port USB header converter. Ideal for CM4IO based systems.

And if you want a flash but quality keyboard for your RISC OS needs, we’ll have some on sale that will literally flash – if you ask them to!

With individually backlit near silent Cherry Red MX keys, you can emulate the Retro look of an A3000. And with a few keystrokes, an A3010! That’s right, you can colour each individual key to whatever colour you want.

And, of course, we’ve got a couple of other developments we’ve been quietly refining in the background – ideas and innovations that have kept us excited at RISCOSbits HQ, and we can’t wait to share. Maybe even a throwback to 2005, “adjusted” for the modern 32bit world.

We’ll be showing off, for you to order on the day at special Show prices, our ECOS and ECOfile range of companion systems, to enhance your RISC OS experience by using the best of other OSes.

We’ll also have a selection of clearance stock at bargain prices, some lovely stickers and badges, also available at special low prices. Plus a few other decorative items that we’ll share in due course.

Whether you’re a long-time RISC OS veteran or completely new to the scene, the RISC OS London Show is the perfect opportunity to see the latest developments, chat with us, and explore what RISCOSbits has to offer. We’re excited to bring something for everyone—and we look forward to seeing you in Harrow!

RISCOSbits’ London treasure trove

It’s now only a few more days until this year’s RISC OS London Show, which will take place on Saturday, 25th October, at the Harrow District Masonic Centre – and last night was the latest RISC OS User Group of London (ROUGOL) meeting, at which RISCOSbits gave us a teaser of what to expect from them at the show. So here’s a more detailed run down directly from the horse’s mouth RISCOSbits keyboard: We are pleased to announce that RISCOSbits will be exhibiting at the RISC OS London Show on…

Fireworkz Pro 2 version 2.33.00 released

https://www.iconbar.com/articles/Fireworkz_Pro_2_version_2.33.00_released/index2245.html

R-Comp has released a free update for Fireworkz Pro.

RO5.30 Why is SVC Stack Protected from USR Mode Reads ?

When running on RO5.30 !ARM_Debug generates an abort for LDR R4,[R2,#0] where R2=fa207fe0, running in USR mode. This is a read to the supervisor stack. This area of the !ARM_Debug code is running the ‘LDM’ instruction in a kind of ‘sandbox’, and requires access to read the SVC stack. I’ve not spent any time looking at this area of the code – it just seems to work after the usual TEQP/MSR/MRS PC changes – until now !

Note: The same !ARM_Debug code runs correctly on RO 5.28.

The RiscOS 5.30 release notes state:

“Memory protection on the supervisor stack has been enhanced to improve system stability”.

I can understand not allowing WRITES to the SVC stack from user mode. However, why do READS from the SVC stack cause an abort ?

I know that I could modify Theo’s code to switch to SVC mode just for these stack reads. But I could probably just as easily reconfigure the ARM memory controller to make the RO5.30 memory functionality match that of RO5.28. Or just stick with RO5.28 for my !ARM_Debug work for the foreseeable future. RO5.28 seems to work pretty well :-)

Ralph

ps. !ARM_Debug beta (for RO5.28 and below) can be downloaded from:

A new version of Fireworkz Pro 2 has been released by R-Comp (with availability via !Store and on CD at the RISC OS London Show on Saturday, 25th October).

In the new issue of Archive Magazine, we sit down with none other than Hermann Hauser, the co-founder of Acorn Computers, for an exclusive interview. It's not too late to subscribe! www.archivemag.co.uk

URI Launch Sometimes Fails

It’s an interesting side-track

Sidetrack Alert, may or may not be interesting!

On the sidetrack I found that on a newly booted Pi, which does give Netsurf a boot, then double clicking on a saved URI file error’d with, “An application that loads a file of this type has not been found by the Filer. Open a directory display containing the required application and try again”. I did as instructed, opened the folder and to my minor surprise the URI file then did open its target in Netsurf. This is clearly impossible, why would rebooting Netsurf, which would not happen anyway because it was already booted, make any difference.

It turned out that FTPc, in the same directory as Netsurf but unbooted, loads the AcornURI module in its !Boot.

No real surprises then, the AcornURI module is needed to run a URI file.

The AcornURI module is 0.27.

Changing the tick button icon

It’s probably stating the obvious, but you need to set the sprite area in the window definition block ( winddef%!64 IIRC) before calling Wimp_CreateWindow.

+20, +24 and +28 are the pointer to the icon text buffer, the text buffer length, and the pointer to the validation string respectively.

Fireworkz Pro 2.33.00 released

We are pleased to announce the release of Fireworkz Pro version 2.33.00 as a free upgrade for existing users of 2.3x series. It is available to download now on !Store – look in your “My Software”.

The new version includes a number of changes including:

• Improved load / save performance on modern systems (helpful on SD-based systems)

• VerityMono font (included) is used where monospaced fonts are presently used on systems that don’t have DejaVu Mono already present. This improves on-screen presentation especially for older computers or those running vanilla RISC OS 5.

• No longer leaves hourglass on exit (thank goodness!)

• Updates for national holidays dates in 2026 and 2027

• Improved documentation and example files – updated content, fixed links and extended function examples

• Correct handling of 2-colour toolbar sprites

• Built using latest tools for improved SWI performance, but still compatible with older systems

Overall this new version should perform faster and look nicer than previous versions, whilst fixing some bugs.

Users who qualify for the update can download now on !Store. We’ll also have CD versions (can be put on USB stick too, but bring your stick as we’ll only have larger ones for sale) at the London Show for people looking for physical copies. Existing users can purchase the CD/physical edition for a very low cost making it an ideal show-trinket, whilst other folks can take advantage of show prices on upgrades/full copies.

Fireworkz Pro 2 is an office suite for RISC OS with word processor, spreadsheet and database facilities. Its spreadsheet elements are particularly strong with Excel import/export. Tabling facilities make it ideal for use with DTP packages like Impression/Ovation with data-driven “live” tables and charts. Web/HTML export is also included as well as PDF facilities.

The software is supplied with several manuals and many examples, tutorials and reference files.

For more information, please look for it on !Store.

A Puzzling Addition to the Platform

And there’s another new build of Puzzles (f24329d) up on my site. A few more bug fixes and minor tweaks to the RISC OS front-end, along with an update to the upstream code (which I believe is a fix to a bug in Palisade).

See https://www.stevefryatt.org.uk/risc-os/games for details.

Live Coding with Gerph, Sunday 19th October at 1pm.

Mostly good session. The OS_* SWIs were implemented (OS_ReadVarVal and OS_SetVarVal), and seem to be working ok. Error numbers were set properly, and code variables are now implemented. However, they’re only working in 32bit RISC OS. 64bit RISC OS has a different interface, which I’ve implemented, but quite apart from the code variables, I seem to be getting errors back oddly. I suspect that’s CMunge, but I’m not completely sure. I’m investigating.

Over 40 years ago we played 'Hopper' on the BBC Micro/Acorn Electron and 'Frogger' in the arcades. Today it's become 'Crossy Road' for mobiles and tablets. There was a rumour that 'Hopper' was named after Andy Hopper, a senior employee at Acorn Computers in the early 80s. Very likely a myth!

The last hurrah for the current Q50 Skyline will be a 400hp special. Seems quaint in the EV era - even a little MG4 XPower would trounce it.

Learning BASIC

I’d second (or third) the Martyn Fox books. There’s also a BASIC guide by Ray Favre but it seems like it isn’t on his website – not sure where to find a copy. The Drag’n’Drop books are also very good. Like Derek above, I bought one at a show last year, and found a few bits to be quite helpful/useful when I had to dip back into BASIC rather than usual C earlier in the year.

I definitely recommend trying to get to grips with the basics (pardon the pun) first – don’t just straight into WIMP coding. Start with things like loops, input / output and maths (etc) with variables. Once you have this, and start to “think in code”, then nail down things like arrays and allocating (DIM) blocks of memory and get a handle on bytes and words using ? and ! operators. The latter is important for Wimp programming, but can be quite confusing if you’re not fluent.

Having recently updated TrainTimes to version 2.07, Kevin Wells has already brought out another new version of his application for checking up on railway timetables and other related information. Version 2.08 sees the addition of ticket office opening times to the station details window. Kevin has also dealt with an oversight in the previous release, whereby he hadn’t taken into account of stations being added, changed, or deleted when allowing station details to be viewed from a sub-menu in the Change Station section of the application.

RISCOSbits asks that you get your London Show Special Reserve orders in now

Sadly, though, they’re not asking everyone for their drinks orders for the day. It’s now a touch under two weeks (or is it a touch over one and a half?) until this year’s London Show, which takes place on the 25th October at the Harrow District Masonic Centre, and it’s time for another exhibitor announcement – this time from RISCOSbits. It seems that the team at RISCOSbits will shortly be taking “an impromptu, badly timed and slightly inconvenient holiday, immediately before the show,” which means there won’t be enough time…

RISCOSbits Special Reserve at London 2025

It’s okay. We’re not launching a RISCOSbits Whisky at the show, it’s just your chance to reserve items from our Show Stock.

Due to an impromptu, badly timed and slightly inconvenient holiday, immediately before the show, we’re out of time to take orders to build up pre-ordered machines to be collected on the day.

So to make amends, we’re offering a chance to reserve items for purchase on the day. We’ll have the following items on sale:

VENOM – premium compact NVMe machine

FAST NVMe – another excellent premium NVMe machine in a full Mini ITX case

DIY Systems – we have the ONE, TWO, and THREE systems available to reserve

Chimera – a multi-headed machine with a special free surprise for the show!

PiRO Qube – the smallest NVMe machine possible!

eNVy.Me – a modern, lightning blue NVMe system with a unique case

FASTFIRE – our speedy SATA machine with multi-disc capabilities. The fastest true multi-disc systems available.

We’ll also have a few late additions to our usual range with bumped up specs. Plus a range of very new things that should signal it’s worth making the case for visiting us at the show. But we’re not putting those up for reserve. You’ll have to coast on over for those.

To reserve your item, drop us an email at london2025@riscosbits.co.uk to let us know what you’d like us to hold for you.

Reservations will be made on a first come, first served basis. All we ask is that you collect your reserved items by 1pm on the day so we don’t have to disappoint too many people!

RPCEmu 0.95 o Fedora KDE 42 is it possible to connect a Joystick

Hi Alan,

I wrote USBJoystick, however it is only suitable for ‘native’ RISC OS hardware – not emulators. It talks to the built-in USB stack in RISC OS 5 and maps HID devices to the old Acorn joystick API. So if you had, for example, a Raspberry Pi running RISC OS, then you could plug in a USB controller, and it would ‘just work’.

RPCEmu is a hardware emulator of an Acorn Risc PC. Those machines didn’t come with USB (they pre-date it!). You would need RPCEmu to provide some sort of USB-compatibility-layer, which would let USBJoystick work. Or perhaps with less effort, RPCEmu could emulate the Acorn joystick API using whatever the underlying system (Linux, Windows or macOS) supports.

How to set objasm debug options for the Econet module source

There is a thread over on stardot regarding getting an ADF10 Econet module to work on a UNIPOD, it presents anecdotal evidence that this been done successfully before but evidently lost without trace.

https://www.stardot.org.uk/forums/viewtopic.php?t=29655

I have long wondered about that and in a moment of weakness decided to have a look at it.

SO far I have taken the Econet module source from the IOMD build of RISC OS 5 from my RasPi over to a SA RPC with a unipod, and up to date ROOLDDE, where I can build it out of the RISC OS source tree by dropping its make file into amu.

This results in several targets RMs including Econet, EconetSA & EconetD. The EconetSA module works on anther SA RPC with an Acorn AEH60 Econet module, so that’s a good start at any rate.

In the source I can see quite a lot of extra debugging output, particularly around scanning the podules for the right one, an area that I need to rework first. But running EconetD does not result in any debugging output, and nor actually are any of the strings I can see in this code present in the binary.

I have not used objasm before and never explored this mire of macros.

I can see in code section below what appears to be conditional assembly dependent on ‘DebugFindHardware’

FindPoduleLoop

DECS r3

BMI AddressUnknown

[ DebugFindHardware

BREG r3, “Podule_ReadInfo: R3 = &”

]

Push “r10, r11, r14”

MOV r0, #Podule_ReadInfo_SyncBase + Podule_ReadInfo_ID + Podule_ReadInfo_Type

MOV r1, sp

MOV r2, #3*4

SWI XPodule_ReadInfo

Pull “r10, r11, r14”

[ DebugFindHardware

DREG r10, “Synchronous base address = &”

BREG r11, “ID = &”

DREG r14, “Type = &”

]

BVS FindPoduleLoop

BIC r11, r11, #2_101 ; Knock out FIQ/IRQ request bits

TEQ r11, #SimpleType_Econet:SHL:3

BEQ AddressKnown

TEQ r11, #SimpleType_Extended:SHL:3

TEQEQ r14, #ProdType_Econet

BEQ AddressKnown

B FindPoduleLoop

AddressUnknown

LDR r10, =EconetController ; Default for internal hardware

AddressKnown

[ DebugFindHardware

DREG r10, “Address we are using = &”

]

I can see that ‘DebugFindHardware’ appears to be set in this line but I am not making any sense of it:

DebugFindHardware SETL (:LNOT: ReleaseVersion) :LAND: {FALSE}

The make file does not seem to hint at how debug options are set either.

What am I missing here?

The 'alternative' 6502 mnemonics where letters are added to the standard mnemonic to specify the addressing mode - eg LDAIM 100

This format came about because existing macro assemblers could be easily adapted to support the 6502 processor. MOS, the makers of the 6502, didn't support this format.

My point entirely, we each create our own starting point then reproduce them for other applications.

I assume you are talking about the cast of the handler instance information. Yes, can be challenge, I’ll have a think. Currently in my model the handlers are separate to the objects of classes they would handle, their names are just labels and the event/handler only come together in the switch with the event value, now in an enum.

One of my favourite consoles, the Hudson Soft / NEC PC-Engine! Known as the TurboGrafx-16 in North America where, for some reason, it was re-housed in a large, ugly dark coloured case! Games were sold on slim HuCard cartridges and also CD-ROM, if you purchased the external drive. R-Type was amazing!

I wonder how many people have heard of the Bally Astrocade ( AKA Bally Computer System ). Initially released in 1978. It has a really novel controller and is powered by a Z80 processor. Sadly, it didn't have the success of the Atari VCS/2600. Only 41 cartridge based games exist for it.

Any ARM Debuggers Ported to RO5 ?

Thanks to David Feugey for allowing me to use a sub-domain on his ‘riscos.fr’ website, I am releasing a 32-bit Risc OS 5 version of !ARM_Debug. Anybody interested can now have a ‘play’.

This is 32-bit version of Theo Van Der Boogaert’s original RO4 standalone debugger and works independently of the DDE (or whatever). It does require RISC OS 5 to run though:

https://www.fladda.riscos.fr/

This is a first ‘beta’ release and contains some known bugs and no doubt some unknown bugs. All comments welcome.

I next plan to look at implementing SPSR (SVC and USR) support and possibly some co-processor instruction support (these instructions appear to be used in the RO5 kernel).

USR in RISC OS nemoBasic acts as a string operator modifier, causing the string(s) to be treated as UTF-8 instead of bytes. This even applies to the comparison operators, which deal sensibly with malformed UTF-8 sequences (as you can never trust input).

(example uses EXP to expand C-style strings)

The 2025 London Show is less than 3 weeks away...

News from Archive is that the new issue of Archive (Volume 27 Issue 6) will be dispatched this month (October), after several false starts over the summer, dropping through letterboxes in advance of the London Show to help get the word out.

MakeDraw

MakeDraw has been updated to version 2.84 which increases the maximum number of nested groups to 256 (from 64). It also now ignores draw object types &500, &510, &2020, &2030 and &2032 when a Draw file exported from RiscOSM is the subject of a PROCmdInclude() call. This allows, once again, maps exported from RiscOSM to be included in another Draw file being created.

Updated on my web site, !Store and !PackMan.

communications • Re: the Night Owl BBS *MON*

MultiTask

MultiTask has been updated to version 7.76 and now disassembles a few more Draw file object types. It will also concatenate consecutive PROCmdTextTran items such as individual characters in a Draw file exported from !PDF and group them in a named group object so that they can be used as hot links. Transformed sprite objects are now also saved but without the transformation matrix.

Updated on my web site and on !Store.

Today 3.20 Released

I’m pleased to announce the release of Today version 3.20. The application lists events that have taken place (or will take place) on a given date. It contains a database of historical information, to which additional dates and personal anniversaries can be added.

Originally written by James Miskin, I produced a 32-bit update in 2006. Almost 20 years later, following a question at RISC OS North back in March, I went on a hunt for the source code, dusted it off, and have produced a new version with the following changes:

• The application has been built with a toolchain known to be ARMv7 compatible.
• There is now a Help… entry in the main and iconbar menus.
• The date shown in the scan window is updated when the system clock changes day, so long as the window was previously on the current day.
• The upper bound for the day of the month is correctly set when opening the event window.
• A minimum window size is applied when setting the extent of the scan and search windows, to avoid the search results being hidden.

A copy of version 3.20 can be found on my website, at https://www.stevefryatt.org.uk/risc-os/today. It has also been added — finally — to the PlingStore, and if I’ve managed to find the correct incantations it should also show up in PackMan over the next few days.

Originally released into the Public Domain by James, I have applied version 1.2 of the EUPL to the new release to make its status clear, and the source code can finally be found amongst my other projects on GitHub at https://github.com/steve-fryatt/today

I was just thinking "'Snoino' is an unusual brand name"...

@colinhoad.com

The first line of the blurb and he seems to be suggesting the BBC itself got into a fight with Sinclair in order to launch their own computer literacy project. No mention of Acorn.

ZFP Systems at the London Show

It’s now just three weeks to go until this year’s London Show, which takes place at the Harrow District Masonic Centre on 25th October, and the first announcement from an exhibitor has already landed in the RISCOSitory bunker. In fact, the email arrived before last week’s post about the show, so keen was Paolo Zaino, the exhibitor in question, but I deliberately held it back so that it came after the show preview. Using the name ZFP Systems (the brand under which he originally provided professional services to retail outlets…

Happy 39th Birthday to Galaforce - I'm a bit late. Seems like only yesterday when I was working on this game. Launched in September 1986 for the BBC Micro and Acorn Electron, published by Superior Software. Music and SFX by Martin Galway, our 2nd game together. Addditional artwork by Paul Proctor.

You know, you read stuff like this and wonder how it is that these people ever managed to stand up a company in the first place. Do their brains turn into blue cheese after making a few billion or were they always like this deep down? Just utter, utter bullshit. Laughably so.

@kevedwardsretro.bsky.social

Superior Software placed this advert in several computer magazines in 1987 to find new software to publish. 8-bit home computer software sales were in decline and it was hard to find the right software. Their book 'Success in Software' was a very informative guide for would-be game developers.

Added #JVM Stack Operations mapping to my #UltimaVM (see link). But I am thinking of adding indirect adressing:

PUSH.U64 [r0-r1] Push mem val from addr in r0 to addr in r1 PUSH.F32 [r0] Push val at mem addr in r0

tinyurl.com/JVMToUltimaVM #bytecode #VirtualMachine #Coding #Programming #VM #RISC_OShttps://tinyurl.com/JVMToUltimaVM

RPi 500+

if your audience would find it easier to do something another way, and you actively choose to do something different… then you are failing your audience.

If we take that statement literally then almost everything in RISC OS, old and new, could be seen as “failing” the audience. For example, people have been asking for easier development environments or multi-core support for years, and those needs are still unmet (and after sponsoring 2.5M GBP they still will be unmet apparently!).

That said, I do think Steve has a point.

If someone wanted to organise an online-only event (say a “RISC OS Xmas online show”), I am sure plenty of us could contribute material. The format would mostly be one-way, with prepared videos or live presentations and only limited feedback.

In-person shows, in contrast, work very differently. From my own experience, I get much more direct feedback and can respond to exactly what people are interested in. It also allows for spontaneous conversations that just do not happen online. On Zoom, only one person can really speak at a time, and asking questions in front of a whole audience may not suit everyone.

For example, at the last Bristol show I attended, I was constantly busy with people asking questions, and once the initial “ice” was broken, I had some really valuable and enjoyable conversations. That kind of interaction is very hard to replicate online.

So to me, the two experiences serve different purposes. Online events are valuable, but they cannot replace in-person shows. Even for those of us doing free software rather than running businesses, I think the in-person format offers something unique.

Hence I don’t think the in-person shows are “failing their audience”, I think they are fine and having only two in-person shows per year seems to be a good number given the slow pass in developments that are happening on RISC OS (it’s an old platform and it takes time to build stuff on it). There might be space for an on-line event for who cannot attend the in-person event.

For what concern discussing users issues, I think user-group meetings are still way more valuable (either in person or on-line), given the focus of such meetings.

Live Coding with Gerph, Sunday 28th September at 1pm.

Today’s live coding was very successful.

• GSTrans of variables on set now works, meaning that there’s a distinction between type 0 and type 4 variables.
• EvaluateExpression variables (type 3) are now handled on set.
• Number type variables (type 1) are handled on set.
• A new *-command has been added to allow easier debugging of the variables that have been set.
• Simple tests added to check the type, length and returned values from the SWIs have been added. These are run during the CI.
• Fortify is now present in the build, checking that the memory has all been freed (and the memory leaks have been fixed).
• Release 0.02 has been made and, as usual, the binaries are also in the riscos64-status repository.

Missing bits…

• Deleting variables.
• Updating variables.
• Code variables.
• Macro variables.

CloudFS read error

I can understand the attraction of using pCloud directly from RISC OS. But failing that, if you have a NAS, it may be poossible to get the NAS to connect to pCloud, and then use LanMan98 or NFS to access it from RISC OS until CloudFS is revived.

I actually use this approach anyway now. The reality is this approach also boost performance. I let my Linux box do the sync up in the background, while local share is ultra fast like this and has another advantage, as soon as my ShareFS for Linux is completed and working, I’ll “re-share” my pCloud via ShareFS Server, which means pCLoud for old RISC OS 3 on the Archie as well! ;)

So the RISC OS pCloud client is useful only to who has not a 3rd party Linux box in their network.

We have !Launchpad by years now that fully replace Acorn Apps (even on the old Archimedes) and gives all RO systems same features as macOS and Win 11 Launchpads

A quick video of me unboxing NES Silver Surfer. This is a freebie copy that the team received when the game was launched. It's been sat in a cupboard for over 30 years as I have no way of playing it as it requires an NTSC NES/TV setup. Therefore, it has never been played! Mint condition.

Latest news from R-Comp: WROCC meeting, 1st October

The Wakefield RISC OS Computer Club (WROCC) will be holding their next meeting on Wednesday, 1st October, with Andrew Rawnsley taking centre stage to bring the group up to date with all things R-Comp. Andrew will bring the group up to date with all the latest developments at R-Comp and RCI, and with the London Show (at the time of the meeting) just three and a half weeks away, there’s a chance he may be able to share some details or sneak peaks of new releases for the event.

Norcroft 64

I’ve taken a couple of embedded projects from ARM32 to AArch64. The biggest time sinks weren’t the compiler, but hidden 32-bit assumptions: pointer math in ints, varargs, packed structs, and unions. Rewriting inline asm and aligning to the AAPCS64 calling convention was unavoidable. What helped most was harsh warnings, UBSan/ASan in tests, and swapping types to size_t/uintptr_t early. For legacy apps we used a small thunk layer and kept a 32-bit build running until parity.

8-bit acorn hardware • Re: Reading/Writing from the RTC in the Electron Plus 1 AP6

@colinhoad.com

This is 100% insane. Yes, an employer may stipulate this in your employment contract, but that's because *they* are paying *you* for your time, and so the things you create during your working hours are their IP. The tenant/landlord relationship is in no way comparable!

Live Coding with Gerph, Sunday 21st September at 1pm.

Live coding today was another success…

There’s now a Git repository on GitHub (https://github.com/gerph/riscos-systemvars) stub module for SystemVars, which allows simple strings to be stored in a dictionary and retrieved. There are some simple SWIs implemented that allow the interface to be exercised. The module also has CI to ensure that the build and loading of the module is successful – and there’s a small test to exercise the internals.

As usual, if anyone has any questions, comments or even code suggestions and PRs, please fire them this way.

The Sinclair Oxford 300 was launched in 1975 and boasted scientific functions. As with all Sinclair products it was very competitively priced - this one was £29.99, very cheap when compared with similar HP models. It had tiny 7 segment displays and a plastic lens to make them appear much larger.

RISC OS 64bit work status

Quick status update on the RISC OS 64 progress, since I posted last…

• The links on the repository have been updated with pages for individual modules, listing the features that those modules need to have and their current status.
• I’m happy with my implementation of the Debugger module now, and the live coding for that has finished. It’s not quite as functional as the RISC OS Pyromaniac version / the riscos-disassemble Python package, but it’s working ok for me.
• New `Conversions` module implementation which works.
• Most of the `Convert*` modules have now been built, though not tested in 64bit (they’re not really important at this stage, but it’s good to know they build!
• The `IconBorders` modules all build just fine.
• Problems I had with `RemotePrinterSupport` have now been fixed and it builds in 64bit.
• `ResourceFS` stub module is now complete, and obviously doesn’t do much yet.
• `VideoTTX`, `VideoGuard` and `MimeMap` built for 64bit, although they’re not tested and probably won’t quite do what’s expected.

And internally I’ve been updating my build environment to better handle certain cases that weren’t working previously.

• The RISC OS Build service now has the ability to enable faster builds, using the host version of the tools – see https://asciinema.org/a/741270 for a simple run.
• Improved integration within the SublimeText editor – pressing command-B can now build things with AMU locally and highlight the errors inline in the file, or with the build service.
• Improvements to CMunge for 64bit interfaces that weren’t quite right, and the -zerrors switch, that I had recently broken.

The most recent test run says that most of the modules and tools that are present in the repository at least load correctly:

• https://github.com/gerph/riscos64-status/actions/runs/…

The progress for Phase 1 is looking pretty good now, with many components exceeding the original aims for this phase. Still 17 falling short, but they’re probably going to be reletively easy to get to an appropriate state.

• https://github.com/gerph/riscos64-status/wiki/Progress

And the SystemVars module is one of those modules that I will be moving on to in the Live Coding sessions. I suspect this will be relatively easy to deal with, but there will almost certainly be some special cases to handle.

Anyhow that’s where things are for me. You can always follow the repositories to see what’s being done.

Again, if anyone wants to contribute to these, please speak up.

Developers’ fireside chat – 20th September

The next friendly fireside chat for people interested in RISC OS software development will take place at 7:30pm on Saturday, 20th September. Taking place online via the Zoom video conferencing service, these meetings are intended as an informal way of allowing RISC OS programmers, and anyone interested in the subject, to get together online to discuss relevant matters. These meetings don’t have a set agenda, and topics discussed are based on the questions people might ask or what they’ve been working on and choose to demonstrate. For example, topics covered…

Stations more accessible in TrainTimes 2.07

A new version of TrainTimes has been released. The program is one from the Kevin Wells family of applications that use Wget to request data from a remote application programmer interface (API). In this case, the program can be used to check train timetables, as well as find out useful information about the trains themselves, the stations along their route, and so on. It does so through two different APIs – Real Train Times (from whom, users will need to register for an API key) and National Rail. The update…

50 years ago the first 6501 and 6502 CPUs were made available at the WESCON trade show in San Francisco. However, MOS found out they weren't actually allowed to sell anything on the show floor so set up shop in a nearby hotel. Chuck Peddle led the team that created the 650x family of processors.

Debugger module release

Over the course of the last 19 live coding sessions, I have produced a Debugger module which supports many of the things that we expect on RISC OS. We support…

• *Memory
• *MemoryI
• *MemoryA
• *DumpI
• *InitStore
• *ShowRegs
• *BreakSet (not for RISC OS 64)
• *BreakClr (not for RISC OS 64)
• *BreakList (not for RISC OS 64)
• *Debug (not for RISC OS 64)
• *Continue (not for RISC OS 64)
• SWI Debugger_Disassemble
• SWI Debugger_DisassembleThumb
• SWI Debugger_DisassembleArch (for AArch32 ARM and Thumb, and for AArch64 instructions)
• AArch32 instructions are disassembled (default for regular RISC OS), including the FPA instructions.
• AArch64 instructions are disassembled (default for RISC OS 64)
• The module is built and released automatically through CI on GitHub – https://github.com/gerph/riscos-debugger-c/releases
• There’s a project board to record what needs to be done – https://github.com/users/gerph/projects/1
• The module can be built, and runs on both 32-bit and 64-bit RISC OS.
• The module is tested with test code derived from the RISC OS Pyromaniac test suites – automatically within CI.

The module has been demonstrated and run on RISC OS in RPCEmu with !Zap and works as you might expect.

The module can be obtained from the RISC OS Debugger GitHub site – https://github.com/gerph/riscos-debugger-c/releases

The purpose of the Live Coding sessions was – initially – so that I could get some practice at doing coding in a different environment, and demonstrating how some techniques and skills can be used. I was hoping that it would be an encouragement to others that things which seem complicated are largely just a set of small steps to address a problem.

The Debugger module was intended to be a ‘simple’ example of how porting something useful to RISC OS can be done. It wasn’t quite so simple – there’s been work in shell, in python, in perl, and assembler and converting from C99 to C89. And working with someone else’s code which I didn’t understand at first. I hope that it has given people some encouragement to try doing things they wouldn’t have. I hope that it has also shown that mistakes are many and plentiful – and we roll with them. It’s also shown how bad my typing is!

It’s been very exciting. I’ve laughed a lot. And along the way there’s been a number of people coming into the chat and watching the sessions without knowing anything about RISC OS. People who asked questions – even if they’re not on the topic of the debugger – and have been very friendly. That’s been a nice experience too.

So it’s been quite successful, and has produced a replacement module in C for an existing module. Feel free to raise bugs in GitHub, and PRs will be happily received if they’re incremental and reviewable.

Live Coding with Gerph, Sunday 14th September at 1pm

This was the final session on the Debugger. I’m pretty happy with the disassembler now. This final session updated the CI tests so that they (mostly) pass. There were some failures when it was finally integrated into the CI, which I decided to fix offline – they were caused by the use of a non-deterministic part of the table generation in Python. Now that it’s fixed, I think we’ve got a good version.

The Debugger has been published up on the site in the releases section: https://github.com/gerph/riscos-debugger-c

The 64bit version can be found on the RISC OS 64bit status pages: https://github.com/gerph/riscos64-status

Next week, I’ll be starting on a different project – something short, I hope!

You can assemble 68000 code on a BBC Micro if you have the right software. This cross-assembler was published by Crossware in 1986 IIRC. They sold different versions for various 8 and 16-bit processors. The 68K version was the most exotic. Here's a test process going through lots of combinations.

Opportunity for a re-think?

I suppose I should reply to this thread

My view is that if there is any wider future for “RISC OS”, it’s applying the look and feel to the 64 bit OS and applications that I and millions of others are using on Linux.

A lot of what you desire already exists, or at least a runnable foundation does.

https://www.youtube.com/watch?v=LHsHU-dDwAk

Source code here;
https://home.marutan.net/hg/riscwm

Here are a few pros and cons compared;

Pros

• Already runs on 64bit (arm, x64, powerpc, whatever)
• Runs Linux ¹ apps (technically more easily than ROLF, as it doesn’t require apps to be recompiled/linked against a different graphics stack).
• Runs RISC OS apps, via RPCEmu
• Contributing programmers don’t need to be able to program an OS, this is an application written in (comparatively) high-level C.
• Large chunks of contributions do not require programming at all, it is often theme and config file tweaking.
• Small enough in scope to not take person-decades of effort.
• Does not require anyone to pay for tools to contribute.
• Not asking for 2.5 million.

Cons

• It’ll never be able to exactly make all Linux apps look and behave like RISC OS ones, you can theme, tweak widget libraries, but it will never be 100% perfect.
• It’s far too easy to look at the project and go “but that’s not RISC OS” and ignore it completely.

Is it finished? Nope, but if this is something you actually want to move forward with you should certainly give it a go and see if it’s the start you wanted.

Realistically I do not worry about the ‘future of RISC OS’, there are not enough people left, and everyone has a different idea of what it is. But if you do worry about such things, I would suggest working out how to contribute to your dreams, as we are way past just sitting on the sidelines and hoping the future falls into your lap.

¹ Technically it is not hard-linked to Linux, you could run it on top of one of the BSDs, Solaris, etc, something with XWindows on

ROX-Filer and Android Tablets

I can see that makes sense… the snag is the lack of an equivalent of the ‘welcome guide’. Even the maker’s webpages don’t help much and even use different icons to what I see on a new machine! It’s assumed the owner ‘just knows’.

Yes, I did know that Android has avery different interface because it is used on systems quite unlike a standard desktop machine. But the lack of ad init info has been the problem. Taken me ages to get even the basic functions sorted.

He introduced BBC Micros for admin tasks, later to be replaced by RISC OS machines, and by the mid-1990s…

Many moons ago (21 years, actually), I uploaded a bunch of stuff to http://www.lewisgilbert.co.uk. Having left it there, unloved and abandoned for a while, I’ve now put it on my current site Inglenot
The other site will die soon, so if anyone is still interested or linked to it, please check out the new site.
Also, if anyone can update the credits – comp.sys.acorn.networking is still given in the original – I’d be grateful

Random find on some old development disks. Original artwork used in the Amiga version of Sly Spy : Secret Agent - probably also used on the Atari ST. Arcade conversion to home computers by Software Creations. I believe this artwork was taken from the arcade version and adapted by Andrew Threlfall.

Iris 1.033 released - plus a poll/request for feedback

-marm is the standard gcc flag for compiling the binary as ARM32 (as opposed to thumb, or whatever the toolchain is set to). The binary can be whatever – what the JIT generates doesn’t need to match.

It doesn’t change anything, and this statement is technically true (it would be trivial to support arm32 binary with Thumb2 JIT, and vice versa, if you had both JITs available), but it turns out WebKit didn’t have shims between Thumb and traditional so the -marm or -mthumb2 flag would have actually toggled both the binary and the JIT (pre-2018). I think that explains the confusion about using -marm to use the ARM32 JIT.

That’s possibly the reason the preferred JIT is Thumb (as the binary would have been Thumb), though another could be because condition flags seem barely used in the generated code, meaning it’s a waste of memory (space and bandwidth) (4 bits per 32-bit instruction wasted, so may as well use 16bit thumb). I imagine they’re barely used because it’s a very simple optimiser which works on all supported CPUs (at the time: SH4/MIPS/ARM32/AArch64/x86).

Live Coding with Gerph, Sunday 7th September at 1pm

Yes. Feel free to try it – it’s in the riscos64-status repository.

The CI hasn’t built it properly since I started introducing the tests, but I try to put a version in that repository after it has been updated. https://github.com/gerph/riscos64-status/tree/master/r… has the 32bit RISC OS version.

The 64bit version also works too – you can load that into the RISC OS 64 shell and see it working…

Go to: https://shell.riscos.online/static/term64.html

Then:

*URLCopy https://github.com/gerph/riscos64-status/raw/refs/head… Debugger
*SetType Debugger Module
*RMLoad Debugger

and you can use it as you might expect – as stated breakpoint handling is not defined yet for 64bit.

The demonstration in RPCEmu in episode 11 starts at 2:39:54 so you can see the module being used inside !Zap.

Around here is where I’m loading up RPCEmu to test the module: https://www.youtube.com/live/sb2PBL2QmVA?si=_ezJA1CaCl…

The module is tested on RISC OS Pyromaniac, and I’ve demonstrated it on RISC OS 4. I assume it works on RISC OS 5 – other than the breakpoint handling it’s not doing anything special, and nobody’s reported any issues. Then again, nobody’s actually said they tried it so… meh…

Who remembers when you had to put CDs into a special caddy holder before you could put it into the computer's CD drive? Crazy times!

Jokes apart, nice Andrew! I bet I can train Copilot too with my RAG + Knowledge DB, inthe end it’s OpenAI itself. I’ll check it out, thanks for sharing this.

Looks like to create a custom LLM you need a M365 subscription, we use M365 at work and they have begun building custom LLMs to try and help people at work with troubleshooting.
