I corresponded with an individual who purchased a Moog Modular reissue. He sent me some photographs from the Moog Sequencer Complement B which I found interesting to see how they handled the design. Here is the front of the sequencer cabinet which is true to form.

Here is the rear of the sequencer cabinet which is also true to form.

The cabinet wiring is similar although the barrier strips have been upgraded. Even the labels on the modules are true to form.
From the photo of the main PCB, the 960 architecture is the same but the RTL components have been upgraded to 4000 series CMOS operating on +5V from an on-board regulator. This PCB has been completely redesigned with all circuitry on a two sided silkscreened board.
From the photo of the PCB, the 962 design took a different approach. It appears they kept the original PCB layout and circuitry but designed adapter daughter boards to replace the RTL with 4000 series CMOS.
For comparison, here is the original PCB layout of the same area.
