I just got a Batronix eprommer last week. I assembled it and run the hardware test and everything is successfull. But when I try to burn a 29c256 chip, it programs it and verifies it, then says "reprogramming sectors xxx" and it will loop this until I hit abort. I know I have all of the hardware settings correct. The jumpers are correct.
Also when I try to read from my stock chip, I get a different reading everytime I hit READ. I emailed the people at Batronix but they take forever to answer.

Has anyone had problems like this?

Thanks ahead, and sorry for the long post.
