I don't guarantee the following, but you might find it interesting.

It has been noted by some people that the 65C02 has problems working in
the Apple II+.  Bill O'Ryan (local to Madison,WI) noticed, for example,
that a BNE across a page boundard on his GTE chip would branch 1 byte
too short.  He figured that the data was not coming in from RAM fast
enough so he implemented the following change which seemed to fix his
problem.
Replace the two chips (74LS257's) at locations B6 & B7 with the faster
74F257's.
This is all I know about it.  If you have problems with the 65C02 you
might try it out.  Let me know if it corrects your problems.
