ERROR READING AND WRITING M27C1001 AND AM28F010

tl866 plus problem reading and writing memories M27C1001 AND AM28F010. You can only read and write on the old minipro in version 6.71. The old version 6.85 also read wrong The only thing that read and write correctly on the minipro tl866 was version 6.71.

How to solve this problem? I can't use an old version of software because when I running the 6.71 version of software they show error message like this. The current application software verion is too old  and not available. Please download the new  application software.
I'm using TL866A programmer.

Test made with 3 different adapters. Everyone has the same error. I don't think it's the adapter. It is softwere. I have the old minipro in version 6.71 and read on the 3 adapters 100%. However, if I use version 6.85 in the old one, it also gives an error. it only works 100% in version 6.71.

it maybe bad PLCC32 adapter.
DIP32 is same as PLCC32
I tested a DIP32 is normal. 20 05 is a device ID, may be your PIN A9 connect with VPP.note:
the adatper:   PLCC32 to DIP32   not PLCC32 to DIP28

    Then you can see about this on the tl866 plus, sorry for the translation.

Blank chip on the tl866. Example M27C1001 everything appears 20 05. FF FF should appear.

Discover the translation above, I bought the tll 866 plus. However, he is not reading correctly and does not write the above chips correctly. I also have the old minipro tl866 version 6.71 and read these memories perfectly.
