Intersil EPROM

What is the end result ? Is it to fix the equipment or to program those
parts ? What is the source for the EPROM data ?

If  it is to fix the equipment, I would suggest using a 27C16 and make the
necessary pin adjustments in a homemade carrier ( two 24 pin sockets plugged
into each other with the necessary pinout adjustments, i.e. unnecessary
address pins tied to ground, etc... ). Looks like a standard JEDEC pinout.

Best regards, Steven
