8 pin or 16 pin ZIF sockets?  A bipolar 8 pin PROM I'm not familiar with.
However, a possibility might be something like the Xicor X2444 - a 256 bit
serial-access EEPROM, which was contemporary with your box.  Darned useful
little chip too--TTL compatible--can be programmed with a bit of software
driving a parallel port.  I've got a bunch of them in my hellbox and like
to use them where I need a little non-volatile information.
