Re: WTB Williams Special Chips

Hey Paul,
I checked with Bob, but he came up empty. The Classic Williams special
chip is a SC1 and carries a different part number. It does have the same
pinout though. I wonder if it's the same chip, maybe running at a higher
speed. Does anyone know if these are truly special, or just specially
numbered off the shelf chips?
