Hi,
I have a Dragon's Lair PCB that I erased all the eproms on and I am trying to burn them with a GQ-4X programmer. They all erased properly but they will not burn. There is no AM2764DC in the list of devices in the programmer software, but it has AM2764A which seems the same from what I could tell.
It gets to 2% and says it failed, but it does not change any bytes... the eprom is still blank. I erased the eproms with a Logical Devices T8Z for 15 mins.
I don't have an external power supply but I ran the voltage test in the program and it said all the voltages were working.
Any help would be appreciated.
