I've got a couple of ISA boards here with ARM1 processors on; one has Acorn
Podule bus hardware fitted so that in theory it can interact with
Acorn-specific expansion cards.
I'm jumping in here mid-thread though so have lost some of the context - I
can't think of a scenario where you plugged an entire machine (implying things
like keyboard and video interfaces too) into an AT, but there were certainly
all sorts of cards of the "CPU/memory/ROM/ISA interface" around onto which
code could be offloaded.
I suppose the question is: "when is a coprocessor card not a computer"? :-)
