I just gave away my Sanyo Betacord VT-9100A. This was a Betamax format beast from 1979. It had piano keys and 2 knobs for channel selection (VHF & UHF). This was Sanyo's 2nd generation machine where they added the capability of setting it to record a program - 1 program, no more then 24 hours in advance, and the timer only turned the recorder on. It did not stop at the end of the program, only when the tape ran out.
I actually donated it to Big Brothers / Big Sisters, and I felt sorry for the driver who had to pick it up. It weighed about 50 pounds.
