 Hi, I have four eproms NMC27CP128Q250.
I tried to write them all with my VP-280 but without success.
I always erase them first (blank check OK) and use the AC adapter.

The error I get is this:
>>.Program......
>>Device Address:000100H　Device Data:E1H　Buffer Address:000100H　Buffer Data:E9H
>>Program fail!
>> 1,03Sec

I appreciate any help, thanks.
