4827(128G) EPROM Substitute? Can't seem to program them with the GQ-4X Burner
I've tried using the 482764 chip setting (both have the same specs), writing at the slowest speed, with the supplemental power supply attached.
Maybe it's just not possible. Is there an acceptable substitute for this EPROM?
