I have to disagree with you there. I have just looked at the documentation for a
couple of the Radio Shack tape recorders commonly used with TRS80s, and
both have automatic gain control on recording.
I recall using a normal casette tape recorder with my Coco back in the
day. I don't recall a gain control, but I do recall setting the volumn
control way up. Never had a problem reading back tapes.
