My old Rockwell data book says that EPROM's can be erased by exposing to
UV light for 20 minutes. It does not say whether to use long or short
wavelength UV. UV lights are available at novelty and science supply
outlets, it does not have to be a dedicated EPROM eraser.
If you use one of these other UV lights, be sure to shield your eyes from
direct exposure to the UV light. Overexposure to UV light has been
implicated in glaucoma.
