Does anyone have a RiscPC? If so, could you download archive.debian.org/debian/dists... onto a RiscPC, unpack it, and use it to boot Linux? On my machine it hangs starting init and I don't know if it's a hardware issue or a software issue.

The BBC Micro is 44 years old today, Happy Birthday! However, many customers had to wait until early 1982 for delivery of theirs due to limited supply availability before Christmas. During its lifespan just over 1.5 million were sold - exact figures are not known. I still have my original one.

Interesting watch for #RISC_OS users from @adriansdigitalbasement.com about a month ago, where he tries out an A420/1 that was sent to him & learns a fair bit about Acorn history along the way. There's a follow-up video, but I'll save that for another day. youtu.be/zvv06jKcMtE?...

A reminder that this kicks off *tomorrow* at 9am! #AdventOfBeeb youtu.be/RHdgIHr78RM

The closest to that in the states is to have a Raspberry Pi 400 or lower running RISC-OS (The OS of the Archimedes). Funny thing is that RISC-OS is still developed to this day by the @riscosopen.bsky.social project, and as of now the greatest development priority is getting it to be fully 64-bit.

Would love to own an Acorn some day #acorn

November 2025 News Summary www.iconbar.com/articles/Nov... Some things we noticed this month. What did you see?

Drag'n'Drop 15i1 edition reviewed www.iconbar.com/articles/Dra... The latest edition of Drag'n'Drop magazine was released at the recent London Show and should be with subscribers now. Congratulations on reaching Volume 15!

I do enjoy these videos. By this point, the BBC Micro magazines were publishing games listings that were matching commercial quality, a trend that would reach it's peak by the end of the decade. youtu.be/HD556JxYTkk?...

Coding a Fortran program on RISC OS www.iconbar.com/articles/Cod... If you were wondering what to do with that new Fortran Compiler in the latest DDE, Sprow has a very timely article for you...

A huge shout-out to everyone who made it. The next "Coding on RISC OS" fireside chat is pencilled in for 10th January 2026. 🚀🕹️🛸 #Code4fun #ARM #RaspberryPi #OpenSource #RISCOS #Zoom #Meetup

Live Coding with Gerph on Sunday www.iconbar.com/articles/Liv... If you were intrigued by Gerph's Monday ROUGOL presentation, or just want to improve your coding skills, then you are in luck!

Excellent video from @bigcar2.bsky.social about the Atom youtu.be/UvNi0vkZQo0?...

Fireside developer chat on saturday night www.iconbar.com/articles/Fir... It definitely feels like the bleak mid-winter. So why not have a cosy Saturday night in? Throw another log on the fire and join some very informal and friendly chat with other RISC OS developers online.

Fortran 77 is here, just a couple of years behind schedule! www.riscosopen.org/news/article...

A creditable showing for the BBC Micro against various souped-up Apple IIs, but no Second Processor versions which (by the end of 1984) included 65C02, Z-80B, 6809 and 68000 options. All would have been faster yet. Later there'd be 65C102, 80186, 80286, 32016 and of course ARM.

A massive shout-out to everyone who made it. The next meet-up is pencilled in for the 22nd November. #Code4Fun #RISCOS #ARM #Retro #AcornComputers

The 1987 Pre-Release 3D Lander Demo running on an Acorn Archimedes (Yes, 1987 ARM Power!)

Indeed, new stories always emerge at occasions like this. I was lucky enough to see a similar gathering last year when Steve Furber retired from Manchester University.

Moving back to Linux RPCEmu on my Mac www.iconbar.com/articles/Mov... I'm a big fan of RPCEmu which provides an excellent RISC OS environment on my Mac when I'm travelling. In this post I'm going to explore why I have switched back to the Linux version and cover some of the issues I encountered.

Okudagrams are old-hat, so of course must be supported in RISC OS.

I've just uploaded an update to my RISC OS !RMA utility, primarily to fix RO3 compatibility (thanks to Phil Pemberton for the report) but I noticed I hadn't released the previous version that featured an important upgrade - the ability to explore ANY Heaped Dynamic Area. So, a useful update:

BBC Basic is not Perl, but nemoBasic’s long strings and DIV$ operator do make it good at consuming and parsing text files. I’ve just added a long-planned feature: “StrongTabs” seps mode – which isn’t limited to tab characters or one-character separators, but consumes multiple separators as one...

ROOL adds Fortran support in latest DDE update www.iconbar.com/articles/ROO... ROOL clearly have big plans for the RISC OS DDE

BBC Basic is available for multiple platforms and processors, but there’s one keyword (well, two) that’s definitely not portable – CALL. I decided to address that (ha!) in nemoBasic:
