Which brings me to the reason I don't play with the Mac enough to know this: the mouse port is dead. The mouse pointer will move horizontally, but not vertically. At least, I _think_ it's the port and not the mouse. I don't have any mouse-aware software for my //c, but reading PDL(0) and PDL(1) got reactions at appropriate times. So I know that the mouse's innards are working. I'm just not sure I'd be looking at the correct pins. My Mac 512K has these yellow melted-looking packs soldered to the motherboard inside each port. I think they're labeled "FILTER" or something? I was wondering if these things are there to protect the machine's electronics, and if it was one of these things that blew. Are they just miniature fuses? And if so, can I just bypass the one at the appropriate pin to get my Mac working again? I'm just guessing.
