A bit late to post this on Iconbar! So the #RISC_OS Advent 2024 goes on socials! Happy Holidays, all! Here's a sneak peek at the progress on UltimaVM, a fast bytecode interpreter and unified API for RISC OS 26, 32, and future 64bit, as well as other OSes and architectures!#riscos

Turns out it wasn't too late to post it on iconbar.com, Mark is always ready, impressive effort to help #RISC_OS!😂So here it is the update on the progresses: iconbar.com/articles/RISC_…

🚀 News! The #RISC_OS AI User Guide just got a new update: 🎉 🖱️ Better guidance on mouse use in RISC OS 📜 Expanded comparisons of RO 3.1x, 3.60, 3.70, & 5 Big thanks for your feedback and patience! 🙌 🎄 Happy Holidays! chatgpt.com/g/g-cDuJaLfS4-… #ChatGPT #AI #riscos #Acorn

#RISC_OS #ChatGPT Daily #SWI OS_WriteC (&00): Outputs a single character (ASCII code in R0) to the current output stream. If the stream is a terminal, the character appears on-screen. Invalid codes are ignored. Preserves registers (except R0). Use for direct character output.

#RISC_OS #ChatGPT Daily #SWI OS_WriteS (&01): Outputs a null-terminated string directly following the SWI in memory to the current output stream. The return address is modified to skip the string. Not re-entrant; interrupts are enabled. Use for efficient embedded string output.

#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

#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

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_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

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 📢 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…

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.

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

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

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👇
