Yep, it's entirely possible, especially if the label on the EPROM fell 
off, that the chips could have bit-rotted.  It takes 10-15 years if the 
chip is properly covered (the actual bit rot itself only takes a couple of 
months as the chip erases itself), but if uncovered in direct sunlight, an 
EPROM can erase in mere weeks.  Nothing wrong with the chip, it's just 
erased.

OTOH, I have no idea why I wasn't able to get my SCSI card working when I 
was first *trying* to get it working, even after burning the Rev C EPROM.  
But when I found the Transwarp, I plugged the SCSI card in (with the same 
hard drive) and had no problems.  Maybe it was the RAM board, or maybe it 
was just the SCSI cable.
