I have a TI-86 which I accelerated by removing the C13. I didn't replace it with anything, and it works just fine. However, because most games run far too fast now, I'd like to make the speed adjustable. I'd like to use a variable capacitor of some type. Does anyone know what type of variable capacitor I should use and where I can get one? I think Boris Lutz's page used to have information about this, but it seems to be down.
