it certainly doesn't use any 68020-only commands, the 68040 supports all of them except for a few extremely exotic like 'callm' and less widespread FPU functions. The 68060 has a few commands that must be emulated in SW but those are still pretty exotic for QDOS programs, like 32x32->64 multiply, movep, cas2 and a few similar. Richard
