I am trying to program a 2764A chip but am failing. Here is the exact text of the error:

===========================================

==========================================================================

Identical error occurred using devices '2674' and '2764A(12.7V VPP)'.

Exact text on the chip is as follows:

LD2764A-20
U3160150S
PGM @ 21V
<copyright> i '88

I have tried plugging a 9V power supply into the programmer, but I get the same results.

Any idea what I can do to get this to work?

If you are sure your chip is a good chip. Then you can send your chip with the programmer back to MCUmall for checking. MCUmall will make it work. It is free of course.
