ISTR there was some Commodore diagnostic software that you could
transfer that way, and we certainly used the same technique to transfer
diagnostics from a BBC Micro with a disk drive to cassette-based
machines we were testing or repairing. That would be around 1982-85.
We put resistors in the cables to get the levels right.
