Happy Holidays,
So this happened: I forgot to Erase the EEPROM, which clearly is my fault, but it was late and I was tired.
Just trying to see if I can recover this EEprom at all or if I am better getting a couple of new ones from eBay?

This doesn't seem to be one-time-programmable. Have you tried flashing it on Linux instead of OS X ? Are you doing ISP (In system programming, i.e. with a test clip like SOIC8 or SOIC16) ? At the moment it's unclear to me why your erase operation is failing...
