Based on the available schematics, the 661 appears to have been designed in 1961.  During what years was it manufactured?  Why is it that the 661 has a dedicated high-speed coaxial interface between the sampling unit and the timing unit and later 560-series sampling systems (3S2, 3T77A, etc.) are able to simply use the regular plug-in connector and mainframe wiring harness for routing trigger and timing signals between the two units?

Some 661s have a multipin connector on the rear panel, perhaps to allow the 661 to be interfaced to low speed data acquisition equipment
or a computer.
