Looking at this schematic, I see no way that this could possibly work.
The capacitor thing seems like a big joke, along with everything else.
I'd say that the best way to make a IR link would be to have a powered
device that uses transistors or logic ICs of some sort. When I've
connected a plain old green LED to the receive or xmit and ground on my
82, the cursor freezes. When I take a voltage measurement with my
voltmeter, no freeze. It seems like the high current draw is the
culprit for locking up. The IR link seems very possible, more so than
rt-link, which also seems possible. Any info on what the data lines on
the TI calcs would help me.
