Solar UV radiation w/o intensification has been shown not to erase most
eproms.
Intensifying it w/o doing something about the IR and visible will
probably melt the device, so you get complicated enough to make it not
interesting to do so.
I do have a question. I have a deuterium source with quite a kick.
Anyone have a guess what a deuterium lamp full spectrum would take to do
an eeprom? I would not put hours on my good source to do routine
erasures, but in a pinch it should be more than enough to do the
erasure. I don't have a programmer to check erase state with right now
to answer the question and am asking more to get a pointer to the spec
as to what it takes to erase than anything else.

Also have a mercury source:

but running it scares me.

. There are a hundred Chinese vendors selling the same thing. I just grabbed
one at random.
Call me old fashioned, unknowledgable and noob; I am, in fact, all
of
them. But couldn't you just put those things in the sun?
Which was always the 'scare' when you saw a 'stickered' EPROM and the
sticker fell off, with sunlight coming in strong and heavy ;)
