Posted - 12/08/2018 : 14:28:08 I have the GQ_4x4 and am working with 28C64 8Kx8 EEPROMS. I can program a new Altera chip no problem; but I need to sort out a pile of old used XICOR X28C64 chips that I believe have SW data protection.

How can I implement this in a script to disable it and to allow me to write to the chip? My attempt at a script is below (did not work):
