Old HP scanner

Amphenol has made all sorts of connectors and they don't generally get named
as Amphenol xxxx either - military plugs/sockets are all named by a MIL
standard/spec (or other alpha-numeric designations) and they become that MIL
number/letter name after a while even with the public.

Look at the standard 25 pin "serial" port - named DB-25, serial connector,
others but yet I have non-computer/non-serial equipment that uses it too.
The same goes for Mac SCSI - female db25, same as a PC "parallel" port - and
other items use this too such as the backs of serial modems.

No big deal, connectors are connectors and sometimes you have to either
refer/search/call them as they are used in the general industry to either
get a point across or locate replacements.

What we call DIN connectors are also called microphone connectors by CB, ham
and audio enthusiasts...even power supplies use DIN and mini-DIN.

=> The phone companies used a 50 pin connector that was commonly
=> referred to
=> as a "Telephone connector" for their multi-line phones. Later the same
=> connector was commonly used for SCSI devices so it came to be called a
=> "SCSI connector" but in truth both connectors were made by Amphenol. At

=> manufacturers of printers and they used it for their standard printer
=> connector. FWIW HP developed an instrument control system
=> called "HP-IB"
=> and it used a 26 pin version of the same connector so that one
=> became known
=> as an "HP-IB connector". Other companies utilized the HP-IB concept but
=> called their systems GP-IB so now the 26 pin connector became known as a
=> "GP-IB connector". BUT they're all made by Amphenol!
