So I picked up a used PPC6800 today and found out that when I type, on almost every key press like 2-4 letters are entered... (which makes using the keyboard almost obsolete) Is this a common problem anyone's ever heard of? Solutions? Thanks

I sprayed mine with a good contact cleaner. It used to be available at Radio Shack, called Caig Pro Gold.

DON'T used any simple solvent which can damage the plastic.

I will give it a try. Thanks for the suggestion
