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.
