I was working on diagnostics for cars using CAN in 1995.

If you were dealing with CAN back then then you of all people know it wasn't the norm at the time.

  • That was after the first 20 years of automotive computers, though, wasn't it, if only barely?

    WP says, "In the early 1970s, the Japanese electronics industry began producing integrated circuits and microcontrollers used for controlling engines.[6] The Ford EEC (Electronic Engine Control) system, which used the Toshiba TLCS-12 microprocessor, entered mass production in 1975.[7]" Reference [6] says, "First half of 1970s: Japan starts developing ICs for automobiles ahead of the U.S.: Development of ICs for automobiles started with analog ICs for in-car entertainment, and was followed by 4-bit microcontrollers and other digital ICs for use with the wipers, electronic locks, and dashboard, and then by microcontrollers with 8-bit and wider bits for engine control."

    But I don't know any more details. Was Toyota controlling its windshield wipers with a 4004 in 01974? Was Nissan controlling a speedometer with an RCA 1801 in 01973?

    Anyway, if we date it from 01975, then 01995 would be year #21.
