Since the 6522 was made by multiple vendors (Rockwell, MOS, Synertek, UMC...), I would think that it's a "safer" chip to use. The 6526, while millions were made, was strictly a Commodore/MOS product, right? While I'm on the subject of 40-pin 6502-family ICs, while fixing up amn AIM-65 this weekend and going through my bins of parts, I ran across both 6522 chips and 6522A chips. Are there any substantial differences? Current drive on the output ports? Anything? -ethan ===== Visit "The Seventh Continent" http://penguincentral.com/penguincentral.html __________________________________________________ Do You Yahoo!? Yahoo!
