I believe the silicon is the same, just some of the pads are not bonded out to the IC package pins. Does anyone know what they do with the interrupt inputs? I assume that they wouldn't make an extra step to explicitly disable them, so they must be safely disabled by default on the 6502. -Chris On Mon, 16 Dec 2002, Matthias Hartl wrote: > Hello, > > Can anyone tell the difference between a 6507 and a 6502 apart from the missing pins?
