VP998 and AT93C56A Reply

Hello

I try to programm a AT93C56A

I used the small ISP adapter supplied with the programmer. I connected each wire to the pins of the eeprom support, following the instructions. (isp drawing)
The programmer writes that writing is ok, but when I try to read. the eeprom to check by opening the buffer, the file is blank.
I tested several new eeproms and always the same observation.

Where is my mistake?

For the ISP configuration, I think I will resolder the eeprom on the motherboard and use the Pomona SOIC-CLIP model 5252, powering the motherboard.

I think these microcircuits are better to read and write directly in the connector DIP
