In the "old" days, such as the
1970's, pretty much any
DEC-manufactured peripheral was supplied as a bunch of cards
that plugged into a specific backplane section, generally 9
slots, I think. A couple double-wide slots were for the
Unibus in and out connectors.
There were plenty of 9-slot system unit peripherals,
but there were
also 4-slot system unit peripherals in the early days.
