I've tried 10 different EPROMs (M27C322) and 5 different filed, every single one had a write fail. I'm at my wits end trying to figure out why. Using adapter for the 42 pins

Brand new programmer/adapter. Installed software/USB drivers. Windows 7. Start up, put in adapter, put in EPROM, blank check, all good.

Chose file, click write, get to 50%ish and write fail.

Disabled Data execution prevention for it. Tried writing at lower speeds. Still failing.

EDIT: now they write 100% but fail at verify at 50%, where it used to write fail...


Any help would be VERY well appreciated.

If it fails on exact 50% address 200000, then it must be address jumper not set on 27C322 position.

Check jumper J1.
