The TRS-80 used two formats! THe base 4K with 4K basic was a slower
format than the 12K basic machine.
The MM100 was a modem (bell 103 compatable).
The pocket computer was again different I forget the format.
COCOs I think were not all the same.
Lots of ground to cover.

It sounds like he is contemplating a
battery-powered tape drive
emulator that plugs on the outside of the machine for users to use
without opening their boxes. It would then be portable to other
machines. Sounds like a great idea.
This year's CocoFEST is open to all TRS-80
models, not just the Coco,
and I noticed that many of the models have a similar cassette port
connector (I think they have variations on the format), and so I
thought of a neat project that might be of interest to all of the
participants of the show.
As you note, picking off 5V from inside, while
entirely possible, is
far from optimal, and a uC is the intended recipient. Besides, as
Tony implies, I should know this stuff, but I have indeed managed to
move along in my efforts for so many years without needing to use a
comparator :-)
