Ken,

Modules were common in those days. Often 2 printed circuits at a distance of a 1/4 Watt resistor with the components in between.
A good example are the CDC computers from that time. A lot of documentation can be found about the CDC 6600 (cordwood modules)

The book by J.E. Thornton's "Design of a Computer: The Control Data 6600" can be found on the Internet.

Your contraption is also from CDC.

Fran Blanche has something like that too.
