 As mentioned in another post, BBN supplied the cable and specified the signals, but it was up to each Host to supply its own connector.

 Stephane,

See http://www.bitsavers.org/pdf/bbn/imp/BBN1822_Jan1976.pdf , particularly
section 4 and Appendices B-D for a complete description.

I've also been searching for an image of the actual connector, but have
been unable to find it.

Cheers,
Andy
