After all, the good ol' IBM PC used an 8051 to scan 102 keys, didn't it!?

I believe that's true. I believe that Intel still has an 8052 derivative on their website designed especially for keyboards. I think it's the 8052KB (original!), or something like that.

On the other hand, does it scan a 102-key keyboard or does it scan 102 keys? That'd be an expensive keyboard if it up and rolled over after 102 keystrokes. :)
