If anyone's interested, I have a home-built UV EPROM eraser that I can't see ever using again myself. (Everything I do is flash now and I don't see going back to EPROM's.) It was homebuilt from a germicidal lamp and an 8-track storage box and a ballast probably 30 years ago. Of course, there are no safety interlocks etc. Pick-up in/near Washington DC or you can pay for shipping (probably $8 or so.) Tim.
