Some 661s have a 41 pin [[Bendix connector]] on the rear panel, perhaps to allow the 661 to be interfaced to low speed data acquisition equipment or a computer. This is essentially a pass-through from J2 & J3, the secondary multi-pin connectors on the vertical & horizontal plug-ins. These connectors carry switch position information (number, magnitude & units) and clock & gate pulses. Not all plug-ins had this 2nd connector; the [[5T1A]] does, while the [[5T3]] does not. | Some 661s have a 41 pin [[Bendix connector]] on the rear panel, perhaps to allow the 661 to be interfaced to low speed data acquisition equipment or a computer.
