erasing proms????am I missing something????
It was always my understanding that if a eprom has a window on it and that window is exposed to UV light that it should erase. I tried to erase some eproms with my new eraser (dataeraser2/I checked the light and it does come on) and I dont think that they are erasing. So I would like to know if I could just read the chip and look in the buffer. What should an erased chip list -- all 0's or all F's . Im using the Pocket Programmer if that matters.
One last thing, how lon do you guys usually have to leave your chip in for?
Thanks

I have a eprom that erases to all FF's. Pocket programmer doesn't see it as a erased prom therefore it won't re-program.
Nevermind, I figured out what was wrong.
