Don't know if this is "classic" enough, but it might interest some people... https://www.riscosopen.org/news/articles/2012/10/26/risc-os-pi-released-ris… There is a final, complete, stable version of Acorn's classic Archimedes OS now for the Raspberry Pi, making the RPi the cheapest Acorn-compatible there's ever been by a long way. It's based on ROOL's RISC OS 5.19, the latest version of the shared-source fork of RO, based off Pace's version. (That's Pace the satellite-TV/set-top-box/modem company.) RISC OS Ltd is still developing its closed proprietary version based off Acorn's unfinished betas of what was to become RISC OS 4 and still claims that Pace/Castle's version is unauthorised and not legitimately licenced. However, nobody much cares any more. ROL hasn't released a new version in several years and doesn't support modern and recent ARM hardware such as the Iyonix, BeagleBoard, PandaBoard and now Raspberry Pi - it basically just sells (quite expensive) updates of RISC OS 4 for classic Acorn hardware and directly hardware-compatible machines. It rebadged the latest update after 4.39 "RISC OS SIX" just to leapfrog Pace and ROOL's developments of RISC OS 5. -- Liam Proven ?
