Does anyone know if the lights for drying UV cure nail polish will work
to erase EPROM chips? I am trying to come up with a low-cost
alternative to buying a commercial EPROM eraser without having to
resort to building one from scratch. Anyone know if these will work?

Thanks!

It just might. The lamp in my eraser is actually a germicidal UV lamp.
Made for killing bacteria. Lord knows where I will find one if it ever
burns out! :)

You can find one at www.topbulb.com

I built my own eraser with a cord, timer, 15" fixture, 15" germicidal bulb,
and a sealed box with door.

Oh, I almost forgot, remember never look at the light or expose your skin to
it.

Despite the fact that I am probably a bigger cheapskate then the rest
of you, I don't remember the "Walling Datarase" EPROM eraser costing
too much. I think it was like $20-25. (but that was probably 10 years
ago)

The truth of the matter is, yes it basically cost the same or more to make
one. I have about $60 in mine, most expensive thing being the Timer. But
hey, I can also erase 50-60 roms at a time. That being the major difference
I guess.

I bought my eraser (and programmer) from these guys:

http://xtronics.com/memory/EPROM.htm

Their eraser will do five devices at a time, has a safety interlock and
adjustable timer and is only $56 bucks. You'd be hard pressed to build
one cheaper unless you just happen to have the right surplus parts
lying around.

Years ago, I use to just set the chips out in the sunlight for a couple
of hours, worked fine for chips in the 70's. Never could understand
home the school could afford a programmer, but not an eraser.
Keep this up and we'll need to start registering C.A.R.G.V.A.C members.

FWIW, I've got a spare, big Spectroline bulk eraser that I'm going to be putting
up for sale soon. It's one of those that handles 100+ at a time - it think it's
a model PC3300 - I'll check later in the day. Anyone interested please drop me
a line with an offer.

There's a 3300 currently on eBay with a $45BIN. I'm not willing to sell mine for
that low...

It's actually a 2200 - little bit smaller, but only about 25% from the looks of it.
