<<Kurt>> <Mark> <<...Folks seem to think that seeing the UV light instantly fries your eyeballs. If so, then we'd be blind on the first sunny day. I'll just erase EPROMs this way till I need glasses...>> <...it takes a couple of weeks to clear out an EPROM in sunlight. With my G15t8 bulb it takes 3 minutes, at the surface of the bulb. Thats a factor of 6000 to 1... These suckers are not to be taken lightly.> My understanding is that UV damage to eyes is long term and cumulative. Kurt is right; it won't instantly "fry (his) eyeballs". However, Mark's point is that each erasing exposes you to weeks of sunlight-equivalent UV. Did you know that people (farmers, fishermen, etc.) who spend much of their time in sunlight have a much higher rate of cataract-induced blindness? Let's see if Kurt still erases EPROMS this way after his first cataract operation at age 45! :::::: Software Productivity Technologies --- Smalltalk Project :::::: :::::: Jan Steinman N7JDB Box 500, MS 50-470 (w)503/627-5881 :::::: :::::: jans@tekcrl.TEK.COM Beaverton, OR 97077 (h)503/657-7703 ::::::
