PDP 11/05 NC Backplane pins
View of the pin side of the backplanes installed in the 11/05 NC. The bottom backplane is for the CPU/RAM. The top backplane is a DD11-B, used for peripheral devices that have Non Processor (DMA) Grant continuity such as the M7800 serial card. Click image for larger view.

I was hoping that I might be able to run an RK05 drive from this box, but the power connectors are not compatible (although it may be possible to use an adapter).

I don't have direct photos of the PDP 11/05 S power connectors, but I believe this model chassis is RK05-compatible. Here is a photo that shows the back side of the power connector board of the PDP 11/05 S, note there appear to the 6 and 15-pin connector ports.
