    From Wikipedia:
    Erasure of the EPROM begins to occur with wavelengths shorter than 400 nm. Exposure time for sunlight of one week or three years for room fluorescent lighting may cause erasure. The recommended erasure procedure is exposure to UV light at 253.7 nm of at least 15 Ws/cm2, usually achieved in 20 to 30 minutes with the lamp at a distance of about 2.5 cm.

      yeah! I read exactly that in the windowed mem datasheet.... only that the units are in angstroms .
      the correct time is 25Wsec/cm2,... so a lamp of 12mW must run for 35 minutes.
      I want to see if a xenon lamp of an old camera do the job....

    the silicon matt is VERY electrostatic. not recommended for electronics. good for soldering anyway

      Sorry, there is no model on this device. I just found it in charity shop, I think it’s used for money testing. Just look for something similar

    This is a not good example , I have 2 of "those" but they are not erasing the chips, so you are lucky
