      You are correct, the Studio II used a TA10171V1 video chip. This was the preliminary part number. It is the same as the CDP1861. 

      The numbering was also used for both of the CDP1801 chips. They were:

      TA6889 - CDP1801CUD

      TA6890 - CDP1801CRD

      I used the CDP1861 chip because I happen to have a couple on hand.

      I have also made a CDP1861 replacement. You can see it here:


      If you have other questions, feel free to ask.
