COOL! I think its great to know that some of these old ICEs end up in
the hands of collectors who would use it on vintage equipment from the
same era.
If you think about an ICE for a microprocessor, it has to be at
*least* as fast as the uP that it is emulating in order to keep up
with the target system. It also has to have beefier I/O in order to
keep a buffer of bus transactions and so-on. I remember the one we
used for the 6809 looked like some serious iron with multiple cards in
a cage and some serious cooling fans :-).
