I was looking at that option, but I still have repressed memories from
the last one I designed :P

Getting the PCB layout onto two layers was hell.

If I did it again, I'd use a CPLD and an FTDI FT240X USB interface, but
most CPLDs are 3.3V -- which leaves level translation to a 5V host.

That might well be the path I take -- a custom-designed EPROM emulator
for the Datatrak unit, to plug into the front-panel EPROM board socket.
I was just hoping to be a little lazy and save some effort :)
