Yup, the system building blocks were single-sided

DEC's PDP-1, funky light brown paint and all, is presumably some
contemporary innovation in packaging or fab process?
Actually, the DEC system
modules used in the PDP-1 through the PDP-6
(I think?) were sort of a bad design. Expensive connectors, restricted
airflow, and towards the end they grew too large and unwieldy. The
Flip Chip was a huge improvement.
