Unfortunately I don't have any knowledge of the differences between
various brands of 65C02s

The TransWarp fixes a few things in the II+, perhaps that's one of them.

I did but that was some time ago and I don't recall which 65C02s I tried.
Basically I tried 65C02s till I found one that worked which was the Rockwell
but when I found it wouldn't run P8 2.0.3, I tried another which happened
to be the GTE. Since it worked I never went any further. It wasn't too
important since I almost always use the TransWarp.
