EPROM programmer arrived

The EPROM programmer has arrived as you can see. That's the good news. The bad news is I read both of my Thayer's Quest EPROMs and they had no errors on them. They matched the Thayer's Quest ROM images that everyone has. Oddly enough, they were placed on the board as you see them in the pictures; without proper protection from UV light. So may last hope is to try to erase them and reprogram them and see if that changes anything. I've got a sinking feeling in my stomach that it won't make any difference though.
