Notes:

This circuit module is called ‘Filter Band Pass Amplifier’ and is used in the Azimuth Amplifier and Computer box in the BAC1-11 flight control system. The module was produced in SA-245-A1,-A2, -A3, -EA1 and -EA3 configurations.

These circuit modules from the VC-10 computer are typical of construction techniques of the early 1960’s to early 1970’s. The technique of building up electronic and electro-mechanical units in plug-in card modules was a feature of the Bendix PB-20 system Autopilot upon which the Elliott system was based. A number of these cards and modules are common to a range of boxes. However Elliotts also designed many of their own cards and overall the Autopilot has some 25 different types.
