Thank you for the reply. I am aware that my GQ-2X is discontinued. However, it has been (and still good) for my programmming purposes which oftem done on EPROMS only 27XXXX series.
However, from time to time, I have come across one that I wonder it it is capable of. I am looking for one that can handle the old ones like the ATF22V10 or PAL22V10.
Do you know off hand if the GQ-3X or 4X can handle this...thanks
