Hi There, i am new here, i recently bought the GQ-4X true usb universal programmer, i was able to programmers 93C56B and 93C66B for my office needs, however i could not erase and reprogram P87C51RB+4A all i could do is read the contents..

also it seems the GQ-4x has no support for PIC16C72A, when i select the PIC16C73A on the device, the software hangs and freeze, i need to unplug the GQ-4X from the usb port in order to restart the software..

i am using windows xp with sp3...

There is a software bug on PIC16C73A.

You need to change the devices.txt file, remove the line for PIC16C73A, and add following lines into devices.txt file:

Name="PIC16C72A",ID="XXXX",Class="PIC16F872",Category="MCU",MFG="Microchip",CodeSize="4096",EepromSize="0",Package="DIP28",Speed="5",BEGPRG_COMMAND="8",ENDPRG_COMMAND="E",BEGERASECHIP_COMMAND="",PRG_MODE="0",Platform="GQ-4X";
Name="PIC16C73A",ID="XXXX",Class="PIC16F872",Category="MCU",MFG="Microchip",CodeSize="4096",EepromSize="0",Package="DIP28",Speed="5",BEGPRG_COMMAND="8",ENDPRG_COMMAND="E",BEGERASECHIP_COMMAND="",PRG_MODE="0",Platform="GQ-4X";
