I have one of those. So I would assume that if there were some differences that can be found by software, it would be widely known since the 80s. So far my impression was that all NMOS-6502 behave the same, including the ones from UMC (I have a 1581 with a UM6502A somewhere). The differences started with the CMOS variants.
