Absurdly Obtuse skrev: The 68060 has lost some instructions present in the 68040, so theuy aren't all that similar. You'd have to add an emulation library for the lost instructions, and perhaps a compiler back-end if you want to compile programs to run as fast as possible. OTOH, this may be adapted from GNU sources. Then there's the matter of 68060 running at different voltages, but that's no software matter. But if we ignore the fact that designing a 68060 isn't something you usually do in wire-wrap, a lot of software will crash due to unimplemented instructions. -- En ligne avec Thor 2.6a.
