I have several SET 15 eproms - they have different checksum - some work - some don't  -  is there any info on the eprom that can be read that indicates what the chip is - that is - set 15 or the checksum itself?    the eproms all have hand written tags.  I have several with check sum 8cc1 - yet one seems to work - the other I get a 62 0 error (it verifies okay on my burner).   Problem was would do the set yet the bv would not accept (light up) - tried several set chips - then the bv would work.   I would think if a chip is corrupted - the chip would not work at all.

The only thing I can think of is perhaps the "bad" chip is on a chip that is too slow to work correctly with the machine?  Is the "bad" chip a different speed chip?

a set 15 burned to a 27c512 chip should give you a checksum of 002F8CC3
 A set 90 is a better choice for the newer chips.

all the eproms are IT c512s  i have cksum of 8252  8c81 9cc5  and 8cc3  - again all the eproms have non-std tags so I am not sure if they are in fact set15 or some other set chip .

27c512s come in different speeds.  I don't know how to determine speed if it's not printed on the chip, though.

Chip speed will not change the checksum. Chip type will though..  IE. 27-512 / 27c512/ 27sf512 ect,,ect

Barry  I have some Info on 3 different Set 15s , two have the check sum 8CC3 and one has check sum 8252.  If you want, or need a set 90 I think I have a extra one I can give you.

Exactly my point.  If he has, for the sake of simplicity, two chips of the same size with the same checksum, but one of them works and the other doesn't, it could be a speed issue.

I only had 1 that would not work - and it had the 8cc3 chksum - the others "WORKED"?  -  my question was did I have other than set15 or ?  since I was using a standard eprom.
