{ This one quite simply energizes the cassette relay, which }
{ closes the contacts across pins 1 and 3 of the cassette DIN }
{ connector on the original PC. (XT's and AT's do not have }
{ the cassette relay.) The specs allow for 1 amp through the }
{ relay, but having inspected the relay I would play it safe }
{ and attempt no more than half an amp. }
