What's the difference between the Rockwell and GTE CPUs ?

It's strange that the TransWarp (with the  Rockwell 65c02) can run P8
2.0.3 yet the ][+ with a R65c02 replacement won't.  I've noticed some
conflicting reports about which 65c02's will and won't work with P8
2.0.3 on a ][+.  There may be a timing issue with the R65c02 that is
addressed properly by the TransWarp card.

Have you tried running any other 65c02 variants in the ][+ ?
