It should work. The left display should be segments 1-16 and the right display should be segments 17-32. The strobes are shared between the displays.

Sorry. You're right. I have experience with the double display but not the separate L/R displays. The schematic wiring shows that the L display only looks at segments 1-16 coming in on the ribbon cable and the R display only looks at segments 17-24 on the additional connector as well as segments 25-32 on the ribbon cable.

If you have another System 11B (double alphanumeric) display you can connect that to the CPU board and see if it works.
