Not the FIS, but the LSI-11 chipset itself, either
four or five
chips. It's the WD Pascal MicroEngine chipset, with its microcode
rewritten to execute the PDP-11 instruction set.
Um.
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.
