I was wondering if anyone has used an FPGA or similar programmable device as
a replacement for the unobtainable lower-case 2513 character generator in
the ADM-3A terminal. I am trying to avoid fabricating an adapter board to
use a 27xx EPROM since the pinouts are quite different.
Since the only unusual pin on the 2513 is the GND on 10 (and 12 is not used)
I would like to just be able to jumper the board pin 12 to ground and plug
in a 24 pin device with programmable I/O pins to match the 2513 address
lines and data outputs. Does anyone know which device would be the most
suitable?
thanks
