That's interesting - if a strobe tube (like used in a camera flash can 
actually erase the older EPROMs...I'll have to test that out today. I 
have these pistols and rifles that use focused strobe tubes to 
illuminate CDS cells on their targets for a large scale shooting gallery 
I own on a local midway (Pacific National Exhibition - Vancouver, BC). 
So it is an easy thing to fire up - so to speak!
