<DIV><FONT color=#000000 size=2>Against better advice, I purchased a pocket
programmer. It works fine so far with some 150ns 27c128's I used. I purchased
some 120ns chips of the same type, and received what appears to be 70ns. They
are by Cypress Semiconductor. Anyhow, they don't check out on a blank-check,
even after erasure for over 1 hour. The 150ns variety (different mfr. - AM..).
The zero check yields 'found 00, looking for FF'. The program verify also does
not check out. Haven't tried to see if programmed chips work yet. Anyone else
see this? Suggestions, other than 'we told you so..'? What, do I need slower
chips?</FONT></DIV>
