According to the Wikipedia entry, Cannon Electric Company introduced the now-familiar D-Sub (D-subminiature) connector format in 1952. This advertisement in a 1954 issue of Radio & Television News magazine is the first one I recall seeing. D-Sub connectors were a really big deal back in the 1980s when personal computers (PCs) first appeared. CRT monitors used them, printers used them, scanners used them, network interfaces used them, mice and keyboards used them (those that didn't use PS/2 connectors, which were an invention of IBM for their Personal System 2 computers). Nowadays the USB (Universal Serial Bus) and HDMI (High-Definition Multimedia Interface ) connectors have replaced most D-Subs in the computer cable realm. Of course with everything going wireless, connectors and cables of all sorts are rapidly disappearing except those used for charging - and wireless charging stations are obsoleting them as well. The Cannon Type U round DIN types bore a resemblance to PS/2, or maybe vise-versa.

    Kirt Blattenberger,


RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
