Sorry, I should have read the March 1987 "Compute!" article on the new
Amiga 2000 more carefully.
It still appears that the 8088, 68000 and 68020 can all run in
parallel. However, communications among them seems to work like this:
For communications between the 8088 and 68000, 128K of dual-ported
memory is used. Of this memory, 64K is available for general data
exchange between the two processors; the rest is for PC video display,
PC I/O registers and general control functions.
I assume that communications between the 80286 and 68000 would work
similarly. The article, however, does not explain how the 68000 and
68020 could communicate with each other (or with the 8086 or 80286),
if both the 68000 and 68020 are running in parallel.
All this is beginning to make me feel that the learning curve for the
Amiga 2000 may be a little steep....
