I have the programmer GQ4X. and the rev. 1.4. and the software rev. 6.38.
I cant erase it I have the adpater HO1591, ADP-030 and HO3902 to PLCC. I tried several new chips and nothing changes.
I try to write to it and also I cant. Any ideas what I need or what I can do?. As I need to wirte a bin to it.
I get the following messages.
Function not supported or chip cannot be erased.
Error of written Address 0x00000000,buffer= 0x02 device= 0xFF.

New chips are blank, you can verify this with Blank Check.
