EPROM Erasers?

IIRC, it was about 4 days. At one time, clothes (tumble) dryers used to have a lamp called an "ozone lamp". It had a normal medium screw base and IIRC, some made a simple EEPROM eraser from one by installing it in a socket inside of a large soup tin/can. It apparently worked pretty well. In short, anything that provides *short wave* UV will work. So- called "black lights" and tanning lamps aren't much good in that department. But you can easily build your own, given the proper lamp.
