Interesting. It looks to have about half of the modules my old RK8
controller had, I wonder how they managed to shrink it down for a pdp11.
Was the data-break interface for the 8 that complicated?

It seems to match fairly well with the module layout for the standard
(non-double-buffered) RK11-C at

I can't recall mine to a high amount of detail, but that looks about right.
The ribbon cables are a bit out of place... perhaps they were just
stuffed into empty slots to keep them from being damaged.
