Ahhh EPROMs, so much fun to be had with these lil guys. They're everywhere!
It really is a lot of fun to dump old chips and see what they contain. I have a few devices here at the office that I like to update configs on just to hyper-terminal in on and play around with once in a while. EEPROM's are a similar sort of fun, but always feels just that much more nostalgically "legacy."
I've got a USB based EPROM burner which makes easy work of the burning and flashing.
Got my start with this type of thing when I used it to burn EPROM's for my friends and modify their ECU's to accept EPROMS vs the factory read-only chips that came in them.
We'd dump the original EPROM values, adjust things, burn it all back to an EEPROM and pop it in the freshly added ZIF socket. Voila, new fuel/timing maps. :)
