I would like to build an InfraRed coupler for my apple II. I think it
would be usefull for controling IR devices (TV set, CD player...) or
transfering programs from my HP28s, etc...
The best way to do this would be to use the game I/O, i.e. the output
named AN#0 (or something like that) which can be simply switched, and
the game button #2. But my problem is that I don't know anything about
transistors, IC, or anything else!
Has somebody ever done such an interface, or could someone help me doing
this? I would also need some "soft" help, since I only know High Level
Languages, and they may be too slow for this.

Thank you.
