Construction

The Central Processing Unit (CPU) is housed into a rack mount frame containing a Backplane (back) to which several boards attach and a Console Assembly (front) composed by panel-mount buttons and switches plus four "floating" boards that provide Lamps buffering, Switch debouncing and Console functionality.

All CPU interconnections are made throughout the Backplane. Absolutely no cable is attached to any of the CPU boards that plug to the Backplane.
