No, the TG68 does not support 68020 opcode. It has some 68020 features like the 32 bits address bus and pack/unpack instructions but it has not a 32 bits data bus and does not support new address modes.

That's not true. The newest TG68 core already supports all 020+ address modes and some 020+ specific instructions. It's still a work in progress and in the future it will be fully compatible with the 020 instruction set.


That's good news!
Is it the Mikej's project (the 68k pipelined implementation)?
So now your version supports the full extension word format. Is it compatible with one byte aligned data?
Have you added a 68020's style cache to save some bus cycles?

And thank you for your contribution on the Minimig ( soon we shall call it fatmig :-) ).
