I would to make an adapter for my GQ-4X to read/program MX26L3220/6420/12811. I have already figured out the routing to fit the programmer ZIF.
The GQ-4x should be able to handle the correct voltage for the Vcc.

But i wonder what precautions should be done while handling the WE with the Vpp line of the programmer? Also, what would be the correct device model to use for those chips as the basis to create the one of those 3 chips.

Thx
