Tom has managed some very impressive results with Arculator and RPCEmu in a very short amount of time. It's very nice of him to place it under the GPL (as you mention in your blog post) [1] > I've > done a rudimentary port of the code to Linux as well as a load of code > clean ups, and had a working version - although that's now been broken > by more recent changes which seem to have revealed some bugs in the > cross platform graphics library he's using, Allegro.

The RISC OS driver is GPL and therefore redistributable and there's code in QEMU (under GPL) that emulates the chip on it. The only thing I'm not sure of is whether the card itself is 3.1 compatible as it's quite modern, 2000 ish. Links from Matthew.
