This was posted on the net a while back. I saved this because I knew I
would need it someday.
------------------------------
Apparently the so called "6502" used in the Atari's is a custom modified
chip, hence its not using the industry type JDEC number. From Mike at Xerox
comes the following:
Atari 6502c #C014806 standard 6502
pin no. function pin no. function
36 READ/WRITE 36 N.C.
35 /HALT 35 N.C.
34 N.C. 34 READ/WRITE
Therefore one could bend up pins 34 and 36 and do a wire connection to swap
these two pins, but that would still leave you without a /HALT command.
(Presumably the halt command is necessary.) I do not know if the 6502c
chip used by Atari is identical between the original 400/800, the intermediate
XL series and the current XE series.
