I saw this article - good grief, was it really that long ago?!?! :o

In addition to this there were several articles in Byte Magazine (and probably others, too) about how to build an EPROM eraser. One of them was actually called the Coffee Can Eraser (Byte, Jan 1977, pg 91.)

Ironically, a coworker told me about this today. I think I am going to buy one, add an Arduino and screen, keypad and relay and make my own EPROM Eraser.

Those Byte articles all mentioned the damage that UV can do to eyes. Make sure to protect yourself. (I know that you know this, but this is in case anyone else reads this without your knowledge.)
