It sounds like he is contemplating a battery-powered tape drive

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 :-)
