[comp.arch] Zilog Z80,000

I just wondered if there had been anything about this project lately?
I had heard reports that Zilog was working on it many years ago but
never saw any ads by Zilog announcing its availability. Does anyone
know the reason for the delay?

What I heard somewhere: (possibly just rumor):
The 80K was to be a hardwired-logic (as vs. microcoded) 32-bit
microprocessor. They had it up to the silicon stage when the chief
designer left to go to another company. They found bugs in the initial
test run (not unusual -- just ask Intel about the 80386!).  But they
could never find the bugs, and, in fact, had difficulty simply
understanding some of the things that the long-departed designer had
done. According to rumor, they eventually had to scrap the whole
project and start over from scratch again, whereupon Zilog's financial
problems precluded any swift redesign....
