I always wondered if an original 1987 Archi could have been coaxed into running something like Doom.
If that had been available back then would it have changed the popularity of the system.
Mind you, I always wonder what would have happened if they had open sourced their OS back then and provided the source with a monthly subscription update service.

Indeed, being able to run 3D-ish games cleanly would have been a significant advantage for the Acorn over its home-computer competitors. (I think the 3DO platform was also built on an ARM architecture, and was ultimately far more successful in the gaming domain) > Mind you, I always wonder what would have happened if they had open sourced their OS back then The OS still isn't open source even today, long after becoming commercially irrelevant. Quite sad.
- m0xte 7y agoErr yeah it is open source https://gitlab.riscosopen.org/RiscOS https://gitlab.riscosopen.org/RiscOS
- zozbot234 7y agoAIUI, this is a clone of some sort of the original RISC OS (the version that shipped with Acorn machines). It does feature some real improvements, such as being 32-bit clean which is needed for modern ARM hardware (the Acorn Archimedes had a 26-bit address space).
- m0xte 7y agoIt’s a derivative of the original code. Much like the BSD derivatives of the original 4.4BSD source. I think there were some licensing issues originally.
- pmyteh 7y agoIt's not a clone as much as a later version. After the demise of Acorn Computers development of RISC OS continued, but split (somewhat acrimoniously) between two different companies, both producing different versions from diverging descendants of the original source tree. The RISC OS Open code is RISC OS 5, one of those two descendants. It's based on the original Acorn code, though obviously much improved over the last Acorn version. The most significant change is, as you say, that it uses the standard ARM 32 bit addressing mode, rather than the original 26 bit mode (support for which was removed from ARM chips in the mid 90s). Consequently it has been made to run on Raspberry Pi and various other modern SBCs.
- jacquesm 7y agoDo you know who ended up with the rights to BBC Basic?
- pmyteh 7y agoThere's BBC Basic in RISC OS Open; you can configure a Pi to start up at the Basic prompt like an old BBC if you like. It's not the only implementation, though: the language had also been cloned as Brandy Basic (GPL) and also reimplemented in various commercial versions, notably BBC Basic for Windows. In times past there was also a compiled version (ABC) for RISC OS, though I don't know if it's still functional.
- mavhc 7y agoBBC Micro can run Doom too https://www.youtube.com/watch?v=V6HQrXCRZsw https://www.youtube.com/watch?v=V6HQrXCRZsw Just add a Tube co processor and replace the graphics hardware https://github.com/hoglet67/PiTubeDirect/wiki https://github.com/hoglet67/PiTubeDirect/wiki https://stardot.org.uk/forums/viewtopic.php?t=13632 https://stardot.org.uk/forums/viewtopic.php?t=13632

- Lio 7y agoAs I understood it the R-Comp port of Doom required > ARM 3 processor not the original ARM 2 as released in ‘87.
- alexisread 7y agoThe link here is for an arm250 (12mhz) same as the original '87 arch bar the 50% extra speed. I think it's running on a VGA monitor so it'd run faster on a TV. https://youtu.be/jXo6BtmuZkc https://youtu.be/jXo6BtmuZkc
