speaking of which, does anyone know what the restrictions on vcr video
signals are? besides sync, is there a voltage limit (i suppose there is one
because the line in/out says 1.0v peak-to-peak on everything i have).

me and a friend have wondered how tough it would be to record a stream of
digital pulses on a vcr tape and play them back (i.e. cheap HD backup, speed
doesn't really matter). We tried putting the serial port though an op-amp
and recording it on cassette tape, however we had some trouble reading the
whole text file back reliably. are there any bizarre restrictions on the
inputs to a tape recorder?
