As I finally complete my Micro-Altair kit from Briel Computers, my
thoughts turn to the question of how I can get an audio tape interface
working on this machine.
I understand that the MITS tape controller is essentially a serial port
with a simple modem bolted on the rear.
Yes, exactly - but IIRC it was TTL level. And didn't work all that
well. It wasn't too long before I acquired a Processor Technology CUTS
tape interface, which worked only slightly better. At one point I
re-purposed said MITS tape interface serial port (removing the tape
interface portion) and used it to connect to my Atari 800 serial port,
providing printer and disk services to the Atari.
