I've got two EPROM burners. The Watford mk2 is 21V only (so 27128's), 
whereas the other (can't remember the brand) will do 12.5V and 21V. 
The latter was a bit annoying - the cable had been crimped on upside down.

That said, I've not managed to use either to write an EPROM - maybe 
my EPROMs are knackered (not beyond the bounds of possibility, 
they're old). Is there a "maximum" UV exposure time for them before 
they totally screw up?
