I was out today and found an interesting looking box

Controls. It looks like a BiPolar PROM programmer. It has two 8 pin ZIP
sockets marked Read and two others marked Program along with several LED
diplays (TIL 311s! :-) and a lot of switches and pushbuttons on it.
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.
