There was also a WD1600 which was neither PDP-11 nor P-Code, and the
original CPU from Alpha Microsystems. I'd have to do some digging to see if that
and the WD1600 were similar.
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.
