I can tell you that !PC 3.06 or earlier do not work with RISC OS
6. I downloaded the source for it that Aleph One kindly made
open source and fixed it in version 3.08 of !PC. That was
supplied on the last RISC OS 6 CD. !PC was well written and used
the documented APIs but RISC OS ltd changed these in RISC OS 6
breaking !PC in various ways. (IIRC it was things like no longer
being able to find the physical address of the video memory
which !PC needs for good technical reasons plus OS_Memory in
RISC OS 6 is broken.) It works fine with a StrongARM processor.
IIRC it worked with RISC OS 4 as well but I think you needed !PC
3.06. There are references to the PC podule in the !PC source so
it might still work with that. Theoretically it might be
possible to get the PC podule working in an Iyonix by just
recompiling !PC as 32 bit. There is one tiny assembler module
and the rest is in C so it should be trivial to do this, but I
do not think we are in "killer app" territory here!
