Re: Remote triggering an Apple II



What purpose does the resistor serve? I know I've shorted those switch and +5V pins with a wire for testing and I seem to remember it worked fine without damaging anything that I noticed (this was on a II+).

You can do it without the battery, since +5 is available on the

If you're triggering more than one Apple, you only need to connect
to the +5 of one of them, and will only need one 220 ohm resistor.
In other words, just run the "PB0" and "Gnd" lines to the other
computers.
