68764C

[Terryk]

I think it is the same as the 87S180 or a larger derivative.

A few pins are swapped.

Pins 18 and 19 to 12 (VSS)
Pin 20 of prom to 17 of 2732
pin 21 of prom to 20 of 2732

The other pins match the 2732.

I blew several of these out trying to read them as standard 2732's so be
careful.
