"Attached is a picture captioned "Circuits designed by Maurice Gribble for
the Argus 400, 1966 Wythenshawe" from the book "Ferranti - A History" by
John F Wilson.
However the contruction is typical of early 400/500 machines - typically expensive that is! The Micronor II cans are soldered to mulilayer PCBs which in turn are wire wrapped to a multilayer backplane and the backplanes interconnected via a flexible interconnect at what is actually the front of the assembly when it is plugged in to its rack. The large multiway connectors in the foreground are the interface connections that carry a standardised bus to the peripherals and I/O equipment of which huge amounts could be connected to an Argus in process control and military simulation applications."
