I have a GQ-3X programmer and a "EPROM 16 BIT DIP 40" adapter. I am trying to read some 27C400 eproms or even 256/512kbyte mask roms, but I can't get it working. All I get is FFs in the output, infact you get FFs even if you don't have the adapter plugged and try to read without any chip in the ZIF socket. I am attaching a picture of the adapter.

The programmer reads/writes just fine ICs that fit without an adapter. Thanks in advance for any info/help! [:D] [/quote]    Insert an Image File Check here to include your profile signature.
