I want to use a Commodore 64 to turn an AC device on and off.
It seems like this is a simple task, that could be accomplished
with off-the-shelf hardware.  My problem is that I know next to
nothing about Commodores and the peripherals available for them.
From reading the manual it seems like I could connect the user port
to a CIA chip, which would then control a relay.  If at all possible,
I would much rather go out and buy something that is already designed.
Does anybody know where I can find this sort of hardware, and an
approximate cost?
