I am trying to burn some eproms which require 12.5v +-.5v. I have the Willem USB gq-2x. Do I need an adapter as well? The eproms do not work in the device they are in. I'm assuming a USB port is 5V so I need an AC adapter to write them. Correct? I see people talking about changing voltage settings. I don't see any way to do that on the screen. Does my programmer not support it? Or will it support it with the ac adapter? Or am I just not looking in the right place?

You do not need AC adapter. The USB GQ-2X has on board DC-DC voltage step up circuit. It will adjust the voltage to 12.5V.

If your chip is listed in the supported list, then it should be working.
