Why are you so cruel!?!? I've been looking for a PERQ but never found
one at least here in Italy. They seem to be a UL almost like Lisp
Machines of Xerox D-machines. I would trade my 11/40 and my VAX FT 3000
for one of these!

Writing micorcode isn't a job for the faint of heart. At university we
built an 8080 using 2901 bit slices and it was quite a task but sure
was the fastest CP/M machine I've ever used; F80 was lightning fast
compared to another Z80A CP/M box.
