Hello All,
By definition can UV EPROMs (i.e. those with a window) only be erased by UV light? I have a cheapo G540 USB programmer and it has an "erase" function which I believe seems to run on an EPROM and completes OK. But reading the chip shows the old content. I have a UV eraser that is not easily accessible at the moment and was trying to get around having to dig it out. Assuming UV light is it, are the old stories about sunlight true? Can I just leave the chip out for a few hours in CA sun and have it be erased? Just wondering...
