Well, I'm guessing that he's using one of them thar 17C756, or maybe not. I can't tell.

And I'm also guessing that he's using a bunch of switches, maybe even, dare I say, a telephone keypad, probably without any pullup or pulldown resistors (although there are ways around that). Again, I can't tell.

And I'm betting that the search function hasn't been used much, 'cause there's a lot of info out there on connecting 2 PICs together and using a matrix style keypad. I'm at a loss...

Oh, and I've got this car, it's making this noise. Can you help?

Back at ya...
