Thank you for the information. That is what I needed to know. I will get back with you if we decide to update to a newer programmer.

We have a S4 programmer and we would like to program some PLCC chips. We are not familiar with programming these kind of chips and would like to know if it can be done and what we need to purchase and how to program them. The chip is a 29vf040-70-4I-nh. Thanks for any help.
