 I have VP-280 with latest SQ 4.3.4. FW 12.0.
I can not program any EEPROM 27128. I tested 5 peices but still fail.

This is message:
>>Man.Code:89 Dev. Code:83
>>.Blank Check......
>>Blank Check OK!
>>.Program......
>>Device Address:000000H Device Data:FFH Buffer Address:000000H Buffer Data:F3H
>>Program fail!

System-Test: OK
VPP Vol. Cal (21V) = 20.7V
EEPROM chips are user 1st time, cleared wit UV eraser.
What is the problem?

 You can try using a UV eraser to erase the chip for more than 40 minutes. And add VP280"s power. If it is useless, give up those chips, they are at least 20 years old.
