and also failed until he looked at the schematics
for his unit and
found yet another pin out for what appeared to be a 2716 equivalent.
The PROMs in question are NEC2316 about which information is unobtainium.
I think you're referring to the NEC ?PD2316E, which isn't a PROM. It's a
masked ROM. NEC's masked ROM business came from their acquisition of
Electronic Arrays, and the NEC ?PD2316E was originally the EA8316E, so
you can find data in either an EA databook, or an early NEC databook,
such as the 1982 NEC Catalog.

Does it have an NEC logo? AFAIK, NEC didn't ever use "NEC" as a prefix
for their part numbers, which suggests that either it's a part from
another vendor that happened to use "NEC" as a prefix, or that 2316 was
some sort of date code or lot number.
