Anyone know of a source of an inexpensive Eprom eraser. $50 is the best
price I saw. Its almost the same price as the programmer. Thanks

I made my own using a Phillips PL9W miniature fluorescent lamp
adapter plus a PL-S 9W TUV germicidal lamp, both obtained from
a lighting shop. Total cost was about $40 Canadian. The whole
thing is mounted inside a cardboard box. I  also use a mechanical
egg timer -- 15 mins seems to be about right, with the lamp
resting right on the erasing window. There's room for about 7
EEPROM-sized devices at once.

Digikey's ER2-ND is 39.95. No timer. The ad says it will erase most
EPROMS in 3 minutes. Does a PIC take longer than most eproms?
Anyone else have a better deal?

I found mine in Digikey for $35.00.  I think it's called the datarase II, or
something like that.  It's the best deal I found in my search.  It only does
one or two eproms at once, but that's enough for my small needs.

Many years ago, I had discovered that Ozone producing bulbs (used in some
clothe dryers) worked well at earasing EPROMS.  These 4 watt bulbs need a
ballast but I have been operaring them successfully with a normal 40 watt
bulb in series.  The one I have were make by Sylvania and General Electric.
Erasing time is about 30 minutes.
Eye protection is very important but can easily be accomplished according to
the instruction on the Sylvania bulb which states:"Protect eyes,ordinary
glass is sufficient protection".
I now have them in a small wooden box with a piece of glass on top (as a
door) that opens up to let me introduce the EPROM.  I remember paying about
8 or 9 dollars for the bulbs and never had to replace them.

Hi,

I'm also using the DATARASE II erase to erase 16C74. My eraser has a
timer for up to 5 minutes. I can erase up to 4 16C74 at one time but I
need to start it twice, othewise the fuses are not blank.

I've had a great many opportunities to test the erase times of th 16C73
with the timerless Datarase II, and after many trials and a moderate
amount of error I've settled on 8 minutes as a "never (yet) fails" erase
time.  If I had a built-in 5 minute timer I suspect I'd have ended up
exactly where you are (at 10 minutes).
