Here's a quick guide to upgrading your TL866 programmer from the CS version to the A version. This operation enables use of the ICSP port (which is easily soldered in).   TL866a.zip   1: Install the Programmer's software in C:\MiniPro (I used the current version included in the .zip). 2: Plug in Programmer (hope you chose to install the USB driver in the above step). 3: Run Programmer Software and look at the very bottom line. It should show your version TL866CS. 4: Exit back to Desktop.
