I'm hoping hooking up with Apollo doesn't derail it.
 
From Apollo-core.com "Fully User-Code Compatible with MC68000"
 
Sounds good, but hidden behind that lies the answer to "so what is it incompatible with?"

Maybe there will be some coldfire instructions also but in month or two we will know where we stand.

I'd rather have full 68060 compatibility (supervisor/user/mmu/fpu) even if that is less efficient. I'm assuming this isn't going to be open source so that someone else could adapt it to fit this requirement?

There are no user level ISA changes to the 68060 from the 68020 that a compiler would use or target except an FPU ISA which the 68020 did not have. In other words, the 68060 ISA=68020 ISA for almost all purposes.

68060 has a few less instructions than the 68020, so to be 100% compatible it shouldn't have them either.
 
FPU & MMU are also required for 100% compatibility. I don't believe gunnar is going to take over the soft core market, which is what he intends to do. What he's created doesn't really fit the requirement of getting us all access to 68060 accelerators either.
