It seems to match fairly well with the module layout for the standard
(non-double-buffered) RK11-C at
http://gunkies.org/wiki/RK11-C_disk_controller
(slot 1 on the right)

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.
