The MITS cassette wasn't actually that bad. Mine has been spot on since I used an
oscilloscope to calibrate it.
I think the big problem was MITS offered multiple calibration instructions which ranged
from using nothing but a screwdriver and the lights on the front panel to a voltmeter and
if you could afford one, exacting instructions using a dual channel scope. The only
reliable one is the scope.

As I finally complete my Micro-Altair kit from Briel Computers, my

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.
