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.

Never attribute to malice what can adequately be explained by incompetence.
