OK, gentlemen, you've got some good ideas about using the MDL 100/102 for link
to PC and controlling a relay, _BUT_
.
#1, the printer port is OUT only and wouldn't accept any UART data coming in,
better to use the system buss.
.
#2, you also have a relay built into the MDL 100/102 on the CASSETTE port.
This can be controlled with MOTOR ON or MOTOR OFF from the basic program. (yes,
there's surely some CALL ##### to do the same thing.  Just use some light relay
or OPTO-ISOLATOR (4n28) to give yourself a DC amplifier and make the external
relay easily changeable, have an LED to tell when it's on, and hefty enough to
do your job.
. Anyh good info here?  You're welcome,
