Hello,

I'm trying to program some TI TMS 27C010A-12 eproms with my new GQ-4X. Choose the right device from the list. Blank check is OK, writing seems OK but verification failed (gives me a different adress line each time i try a click the verify button).

Any hint of what could be wrong?

EDIT: I've tried to write 3 TMS 27C010A using the programmer with my labtop, all 3 failed. Then i tried 2 using my desktop computer and it worked!

It seems the problem is related to your laptop power. Try to use original USB cable, OR a power adapter on laptop.

Check all pin contacting too.
