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. ** DON'T LOOK AT THE LIGHT FROM THIS RIG! ** (Obligatory warning). Regards, D.M.

It only does one or two eproms at once, but that's enough for my small needs. Stuart Allman Studio Sound Design spam_OUTstudioTakeThisOuThalcyon.com

Thanks 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).
