    Thanks for the reply Dave, I appreciate it. I have read many of your threads/posts and want to thank you for all of your work to help people here. I have read the thread you mentioned and am in the process of picking a EEPROM to use, I found today a few posts on the 3rd Gen Camaro forum where they had used the AT28C64 with similar pin joining on 1,2 and 27,28 as the 27SF512. For whatever reason, my EMP-20 programmer requires a different module than the one for the 27XXX and 28XXX series chips. I think even the 29C040 can be programmed with the same module I have. I could go online and try and find it, but highly unlikely.

    I'll do some more research on the 28C64..they are only $8 so it's not a big deal to try one.

    Cheers
