I thought so. Wasn't for sure what the numerclature precisely. I knew it was
a derivitive of the 6502. Even if its made by Commodore/MOS it is derived.
Well quite identical. Just take the last 4 address pins a break them on a
6502  and you got a 6507. Just at less then $2 a chip why the hell didn't
Atari stuck a full 6502.
