It is PIN to PIN adapter and every pin is OK.First I measure it with multimeter but I believe that it is better to do with H/W Test.

I allready done that, to see does my PLCC32 adapter is ok and YES everything same like I mesuring on ZIF.

I apply switches as selected in Test H/W picture.

DIP switches as H/W picture
When pin 22 is activated pin 31 is 0V

Dip switches as 29F010
When pin22 is activated it is 0 but pin 31 is 4.35V
When pin 31 is activated it is 0 and pin22 is 0 also

In some other post you suggested that voltage on pin 26 A9 should be ~3.7 in my case it is 3.03V.

OK! 1.PLCC chip pins i checked 50 times with multimeter and desolder/solder...they are OK. 2.07F problem was because I try it with DIP28 to PLCC32 3.Resistors I put as sugested to fix HW for new software version http://www.mpu51.com/eprom/image/FixedHW1.PNG 4.pin 22 off=0 on=3,75V pin 31 off=0 on=4,...

Forget to write that I still can not read good ID.I do HW test today once again and all pins are 4.36V exept pin 22 CE# 3.68V.

Here are the pictures shows that it works with empty file

Programming

Verifying

New info: I put 2 resistors 10k on SELIN and AUTO and now I can read,write and verify 29f010 but only if buffer is empty.For example if I press Read in buffer there is 00 00 00... and then i can write and verify that contents of all zeroes, but if I put only 1 (one) byte other than 00 it will not wr...

Hi! I have Willem PCB3 and DIL32 to PLCC32 and DIL28 to PLCC32 adapters that I used before without problems but today I'm trying to write AM29F010B-70JF and having problems. It really drives me crazy... So, problems are I can not read ID there is 07F (chips are new) I can not program them I can read...
