I'm trying to find an image of the 2 chips (error and non-error) to see if I have the error version or not.
TCR shows V6927 as being the "normal" chip with description "MARATHON MOE 2000 OLYMPICS" and V6489.e as an error version with the description "MARATHON MOE OLYM. --CURVED".
The chip guide shows V6927, but not the other. I'm not sure what's supposed to be curved on the error chip, but probably the "MARATHON MOE 2000 OLYMPICS", which appears in a flat text on the lower center.
Anyway, if you have an image of the "other" chip, please submit to CG and post it here.
Thanks -- barry
