Good work!

No voltage during erasing, just plenty of UV light.  A blacklight isn't
much more effective than just daylight for erasing EPROMS.  Basically
anything that won't do real damage to your eyes also won't erase
EPROMS.  Digikey has the DATARASE II with timer for $50.  Get the one
with the timer, because if you forget and leave your chip under UV for
days you'll shorten it's life.
