Virtually *every* HP21MX, 'E-series' machine will have the FFT microcode
that implements several long integer formats (2 and 3 word).

Subject: HP 1000 double integer instructions info
I'm working on adding double integer (32-bit)
instructions to the HP 1000
simulator under SIMH. The 1000 F-Series computer came standard with these
instructions, and I have documentation on the opcodes used. The E-Series
did not have them, but there was a "specials group" product -- HP number
93585A -- that added firmware support for these instructions. However,
the
opcodes were different from the F-Series opcodes to avoid conflict with
other E-Series microcode options.
Does anyone have information on the opcodes used in the 93585A product?
I have found a reference to a manual, HP number 93585-90007, "93585A
Double
Integer Firmware Installation and Operating Manual," but I cannot locate a
copy.
