Oh, I see.  That wasn't obvious to me at all, but I know there are a lot 
of 6502 variants out there.  There's even a chip called a 6504 (6502 with 
some of the address lines missing) that was used as the disk controller in 
Apple Lisa machines.

Will that unit fit the more common Atari 800XL or 130XL?
