If you still have that, could you please check that again? I have a C64 
where the stamp on the chip is '6526', it is seen as '6526A' by the 
software (means new behaviour). But when you take a closer look you  see 
a single 'A' faintly stamped onto the chip about more than a cm away 
from the rest. A photograph is available.

So far I haven't seen a 6526 made after the end of 1986 that wasn't also 
stamped 'A' or 'B'.
