The 172PNN21022 adapter is no longer required because the newer Unity Momentum processors (171CBUxxxxx) have most of their functions already embedded in the CPU.
However, the 172PNN21022 might still be available through the Service Sales group. The Service Sales group handles the inventory leftover, refurbished units and third party acquisitions.
