I can elaborate a little. The 68010 can be directly plugged into the 68000
socket on your Amiga. All the Amiga system software is compatible, especially
the 1.1 release (which was carefully screened for any 010/020 problems). The
68020 can't just be plugged in. However, Computer System Associates in San
Diego (619/566-3911) makes a 68020/68881 board for 68000 development systems.
The board plugs into the 68000 socket. Vic Wintriss, president of CSA, bought
an Amiga and plugged his board in. It worked perfectly, and he got some
tremendous improvements in performance. I think it's another example of just
how *right* the Amiga was designed. ..bfw..
