Ah, yes, incompetence explains it. I'd never seen twinax connectors in use, but there's a twinax antenna connector on the back of my 1955 R-390 receiver that fits an IBM connector.
Twin BNC has one each male and female pin with a split level insulator that exposes the male pin (hope this gets through your spam checker).

Actually, that's not the case. "Twinax" was the shielded twisted pair 5250 terminal bus for Series/3 (System 34, 36 & 38) "MiniMainFrames" from IBM. The original IBM connector was more or less N-style. Shielded twisted pair as a concept has been known for a lot longer however the oldest use I know off was for microphones in the pre WWII time frame. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 [EMAIL PROTECTED] | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence. _______________________________________________ time-nuts mailing list [email protected] https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
