Sorry, going back to your earlier message I see that. I think I skimmed
over it first time and thought of the mini rather than the microproc.
You say the 9440 doesn't have M/D, the book does explicitly indicate
they are present for the 9440 .. the book is in error?
Looking through the Osborne book (Introduction to
Microcomputers -
Some Real Products / 1976), here's another to add to the list: the
MicroNova/9440 microprocessor ca 1977 had built-in 16-bit multiply and
divide instructions.
Can anyone comment on how much use or production the MicroNova or
Fairchild 9440 chips actually saw?
I mentioned the MicroNova. If you weren't DoD-related, you could forget
getting the 9440, 9445,
9450...CPUs. Fairchild wouldn't give you the time of day on those.
Same for the I2L versions of the TI 9900.
