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

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.
