<DIV><BR></DIV>
<DIV><FONT face=Arial size=2>Anyone know how to distinguish the different GM
PROMs after the silver sticker has been removed from the chip (and the chip
has been erased)? I can usually do a silicon signature check on the chip
itself to tell what kind of chip it is but that doesn't help much (narrows it
down to a couple of years at best). We have dozens of chips that don't have a
sticker on them anymore so I don't know what they are.</FONT></DIV>
