Perhaps you're talking about 3000-series
peripherals. ?IIRC, the 6000-
series channels used bundles of coax that were terminated in taper
pins. ?No connectors per se. ?The 3000-series cables were twisted-
pair with real connectors. ?6000-series hardware used 3000-series
unit-record peripherals via a 6681/84 channel converter.
I could be remembering wrongly.
I am thinking about the Cyber 170 channel cables.
