Hello, I have the same problem. I have tested more han 10 MC6821P chips and Autofind fails and Test fails by the TL866+.You can see here my 3 pictures attached.
Is there any specific setting to apply or something ?

Thank you for your reply. But then why is it in the TL866II_List.txt ?

Sorry.Because T48 and T866II is not a VCC on PIN20 , so it only Tested on T56.
and it is a bug we will fix it.

I see. So it will be working with v12.06 ?

papi

Hi, Mr. Admin, I have tried to test the MC6821 with the v12.12 since you said you would fix the bug but it is still not recognised by the TL866II Plus. Do you still think you can fix this bug or TL866II will never be able to recognise this chip ?

it has been explained:
   T48 and T866II is not a VCC on PIN20 , so it only Tested on T56.

papi

Thank you for your reply. So what did you mean on 15 July by : "it is a bug we will fix it." ?

Also, I understand support for TL866II will remain for only approx. 3 more years, but what about support for T56 ? Will it still go on along with T48 after 3 years ?

Hardware replacement is a normal for electronic products.   
T48 and T56 are two products with more differences.


(TL866-3G)T48  hardware will be the last version of the low-cost programmer(I think).
T56 hardware and software will be updated in the future.

papi

Thank you for your reply.
And which bug did you mean on 15 July by : "it is a bug we will fix it." ? A bug in the TL866II or in the XGPro software ?

papi

Please don't forget to reply to my question above : which bug did you mean on 15 July by : "it is a bug we will fix it." ? A bug in the TL866II or in the XGPro software ?...

No note, only T56 support.
In the logic test, there is no classification of programmer models for supported chips

   Dear Admin,                     In cases like this, it seems a hardware limitation from TL866II and T48.
Can you, please, if possible, give an idea, draw a secure board pcb with maybe external power,
and post an article about it, and how to solve it safely? ( like you have done here T48 Adapter DIY (T48编程器自制适配器) - 编程器使用与软件下载 - XGecu Programmer Forums - Powered by Discuz!  with other adapters).

With the T48 population growing , and a big population TL866II already in place for years, your expertise
and knowledge, and happy customers, a path to success!


I know, time isn't never enough.
