rewritten to execute the PDP-11 instruction set.
At the time that the WD Pascal MicroEngine came out, I was informed
(by someone who would have known) that *it* was a re-use of the LSI-11
chip set using new microcode. That was 30+ years ago, so I have no
way to back it up now, but I'm going to challenge you to provide the
evidence that WD came first.
I have no such evidence, but I regard it as fairly common knowledge.
It was explained to me by a DECcie when I was a kid in the early
1980s. How authoritative is the "person who would have known"? The guy
who explained it to me could very well have been mistaken.
