I had an Imsai system and had just gotten a board to carry eproms, and brought one in to put some patterns in it till I got a programmer. We had a lot of mag tapes, and in our area (programmers cube farm) there was a utility area with paper punches, binding supplies, and a demagnetizer a safe distance from anyone's tapes. We paused during a chat among about half a dozen and I was off to one side near the demagnetizer.  With my eprom in a carrier. While the discussion on some random topic proceeded, I idly put the prom on the demagenetizer and proceeded to "degauss" it.  Someone noticed me doing that, and to my amusement, for a bit people were seriously asking about erasing the part with that.  Couldn't maintain laughing long enough to get to far, but was still hilarious. about 78 maybe? thanks Jim
