It would be good as well to dump the Series III main instruction set ROMs,
assuming they're socketed. Bitsavers has a Series II microcode

Close. Without the microcode, they had no apparent way of even halfway
efficiently implementing a large virtual
Warner asks:
"Why was microcode support required to make APL work? What did it enable
that couldn't be done in other ways?" [On an HP 3000 Series III, for
example]
Back in the mid-1970s, on the HP 3000 Series III, the team implementing
APL\3000 apparently decided they would need to implement
I believe it was a performance issue. The APL was so slow without the
microcode assist that the system was unusable.

"Was Lee Courtney involved with the APL 3000 project?" - unfortunately no I
was not. Just RTE on the 1000 and later MPE on PA-RISC. All I know is that
there was microcode support required to run APL on Series II/III
micro-architecture machines. That microcode was not moved to later
