I understand that "ARM BASIC V" was embedded in the Archimedes in ROM. If an ARM processor still supports the original 32-bit instruction set, then (I understand) that this version should run on it, to the point of this being an important compatibility test for alternate implementations of the instruction set. Here is some discussion on ARM BASIC V: https://forums.raspberrypi.com/viewtopic.php?t=61365 https://forums.raspberrypi.com/viewtopic.php?t=61365 This basic version would have been embedded in the original "Arthur OS" that shipped on the Archimedes, and later versions of (modern) RISC OS. https://en.wikipedia.org/wiki/RISC_OS https://en.wikipedia.org/wiki/RISC_OS
