I've been looking at picking up a programmer for a little project, but I'm a little overwhelmed by the choices, and lingo. I was hoping that I could share some information and people more knowledgeable than myself could tell me if I'm on the right track, or off my rocker.
I recently picked up a Coleco ADAM vintage computer. I'm having trouble getting the unit to work, and I'd like to try checking / replacing a number of the 2764 ROM chips on one of the boards. I was thinking that in order to do this I would need to pickup a programmer (I was eying up the Willem True USB), a couple of 2764 chips (eeprom? eprom?) and the code from the ROM chips (obtained from a Coleco ADAM emulator). Then I should be able to send the known good code down to a chip, and do a chip replacement on the board to ensure that I have good ROMs. Am I on the right track? Is this a reasonable thing to do? Will the Willem True USB suit my needs? Do I need any adapters?
I'd greatly appreciate any input.

Yes, you are on the right track. The True USB Willem supports 2764 EPROM. You just need to load the code and write to a blank 2764 EPROM.
Also, I am sure you need a UV eraser to erase the EPROM. See:
