That brings back memories [ :-(  :-) ].

In the "earlier days" we used to program eproms and use them 
with the window uncovered. I guess many of us have found out 
that this is a bad idea. Like Bob's memories, they used to 
misbehave when exposed to light, and quite reasonably so. 
Fluorescents were worse than incandescents. Not erasure but 
just the odd unexpected program malfunction. Bright lamp up 
close = gross malfunction. The stickers aren't just labels 
;-).
