#RISC_OS question: Which versions of RISC OS do you use? Twitter Polls are for single answer, so can you please post your list of releases here below as a comment? We all use multiple versions, and this question is to ensure we are supporting all the most used releases, thx!
🚀 #Hacktoberfest2025 is here! Join the #RISC_OS Community on #GitHub, contribute, earn prizes & badges, and help push RISC OS development forward. Start here 👉 github.com/RISC-OS-Commun… Or check this one: github.com/pzaino/risc-os… ☕️ Have fun & happy hacking! 😍
Only 20 days to the #RISC_OS London Show! And Next @RISCOSitory post about it: riscository.com/2025/zfp-syste…
#RISC_OS London Show is in just under 4 weeks away and here is some useful info from @RISCOSitory : riscository.com/2025/london-sh…
#MyXAnniversary was on the 12th of September, but had a lot of work lately. Anyway, hopefully X will get in a better shape one day, meanwhile lots of things are going on for #RISC_OS and I'll see you all at the London Show the Saturday 25th October 2025! 😃

A note on my #UltimaVM for #RISC_OS users: when coding on Ultima, we don't care about RO multistasking, we just code like on Windows/Linux/macOS. If we want to run an Ultima App in the desktop we just use the `--mt` option in the command line👇

Website is finally live! riscoscommunity.org Works with all #RISC_OS browsers down to !Browse (yep you've heard it!) and expect a bunch of really cool services coming up in the next few months, enjoy! 😎 #riscos #browsing

On Sat 26 April, legends #SophieWilson, #SteveFurber, #ArthurNorman and others will be joining us to celebrate 40 years of the ARM1 chip. Without them, you wouldn't be reading this on your phone right now 🤯 Book here ow.ly/SKJh50VCV2x #ARM #ComputingHistory


This project will finally help sharing files between #RISC_OS and modern platforms in a very easy way and with a robust and reliable new ShareFS Server which can also work across multiple subnets. The Server will also be secured.
#RISC_OS 📢 New updates for both the 2 RO AIs, lots of improvements for both! Thanks a lot to all the people helping with this project! It's great to see the community coming together😀 Details on ROOL's forum: RO: riscosopen.org/forum/forums/1… BBC BASIC: riscosopen.org/forum/forums/1…
INCOMING! Archive 27:4 is out this week coming, and its 52 pages are packed to the gills with RISC OS and Acorn awesomeness. Archive is the magazine for RISC OS users with readers in 18 countries. Don't miss out, subscribe! #opensource #riscos #raspberrypi archivemag.co.uk
#RISC_OS #ChatGPT Daily #SWI #OS_CLI (&05): Executes a supervisor command string pointed to by R0, null, linefeed, or return terminated. The command is processed as if typed in at the CLI. R0 is preserved. Command is limited to 256 bytes. Not re-entrant; interrupts are enabled
#RISC_OS #ChatGPT Daily #SWI OS_ReadC (&04) Reads a character from the current input stream. On exit, R0 holds the ASCII code (C flag = 0) or an error code (C flag = 1, &1B indicates Escape). The input stream can be changed with OS_Byte 2. Not re-entrant; interrupts are enabled
We have now passed MORE than 200 users for the #RISC_OS #AI User Guide on #ChatGPT !!!! 🎉🎉🎉 chatgpt.com/g/g-cDuJaLfS4-… #riscos #LLMs

#RISC_OS #ChatGPT Daily #SWI #OS_NewLine (&03): Outputs a line feed (ASCII 10) followed by a carriage return (ASCII 13) to the current output streams. This SWI is used to move the cursor to the start of a new line. Interrupts are enabled, and it is not re-entrant. #riscos
#RISC_OS #ChatGPT Daily #SWI OS_Write0 (&02): Outputs a null-terminated string from the address in R0. If WrchV is intercepted, it calls OS_WriteC; otherwise, it calls the VDU driver (faster). On exit, R0 points to the byte after the null terminator. IRQs are enabled. #riscos
