Having recently acquired a Performa 6360 (which I intend to (ahem) "pimp out", yo,) I attempted to use the included modem and MegaPhone software to call someone. And so I did.
The Microphone port doesn't work. Now I knew that Apple Plaintalk mics were different, but this wasn't a problem with any of my previous Powerbooks (145, 170). I spent over three hours tonight trying to rewire the mic to make it work, because it seems the common ground and the "positive" input (should that be negative?) are in the wrong places.
