How long should you erase EPROMs for? "Until they're done", I suppose,
but does it vary from chip to chip? I tend to stick a big mixed batch
of 2764 up to 27c2001 in (zapping samples blown into EPROMs) and bung it
on for half an hour. The timer on my eraser goes up to 60 minutes.

Is there
anything I need to look out for when purchasing an EPROM
eraser? As part of my current project I'm looking to purchase one.
Make sure it has a timer, or rig up an external timer. All to easy to
forget about it and I've found that EPROMs tend not to work any more
after spending several days under the lamp :-)
