which I had to do anyway
Yes and no, MSD for example keep a database with S/N and calibrations, but what’s to say the EPROM has not been reprogrammed in the past?
Unless you can read it (and even then you would have to understand mapping) you simply don’t know 100%.
For this reason, I would never buy (nor trust) a second hand EPROM, despite what it may claim to be, it’s simply not worth the risk.
