It doesnt seem to erase my EPROMS but is the same kind used in that BYTE article. Could it be that programming an EPROM several times require longer erasure times???? or do I have the wrong UV tube? In any case, the idea of UV light, +25v besides blown eproms and melted power supplies is making me go toward the new EEPROM (Seeq and Xicor +5v EEPROM) -- does anyone know how to order these things from the distributors, often rude and only cater to orders of 10000's ?? thank very much -Ed -------
