Here's what I can recall: in the beginning, there were what were called
'Small Peripheral Controller' (SPC) slots, which took quad-high cards in the
C-F connectors. Older, simpler interfaces (think DL11, RX01/2 controllers,
etc) were quad cards which went in the C-F connectors of an SPC slot. (More
complicated interfaces, like the RK11, RP11, DH11 etc were entire custom
backplanes/system units - 4 slot for the RK11, larger for the DH11, IIRC.)
What is the standard reference for the SPC slot connector signal definitions?
For the Unibus itself there is Appendix B in the back of this manual:

I've been skimming through various other manuals and haven't found a
reference for the SPC slot connector signal definitions yet.
