 Hi

My VP-280 can"t program AMD 27C100 chips, I have 6 chips, from 3 different sources, all pass the blank test, then instantly fail the write test

>>.Program......
>>Device Address:000000H　Device Data:FFH　Buffer Address:000000H　Buffer Data:F3H
>>Program fail!
>> 1.95Sec
----------------------------!

BUT after this fail the chip passes the blank test again.

I am running Ver.: 4.2.0(23/10/2009) software.

Can you help?

Thanks

David

 I don"t think so, I have source chips locally, and bought 2 from the US, every single one has the same issue, highly unlikely to be the chips.

Anything I can try, altering the algorithm parameters?
