It in the intel data book page 3-32 (1988 volume2
peripheral with black cover).
I have that datasheet but the scanner is down.
You're not thinking of the 82078 are you? 64 pin, but very different
chip, both in pinout and command set. If you've got a part number,
I'll go digging for it, but AFAIK, the NEC part was a special for
Apple--I've never seen it anywhere else.
