The TMS9914 is a GPIB controller. So you've got a Z80, GPIB controller, 8
16 pin sockets that are likely 16k x 1 dynamic RAMs, 28 pin EPROM socket
(likely a 27C256), a CTC (Counter Timer Chip), and the 8255 gives 24 bits of
I/O. What it goes in, I have no idea, but I'd hazard a piece of test
equipment, since GPIB is most commonly found there (note the word "commonly"
for the pedants).
