The 3.5mm audio jack is 75 years old, but electrically-compatible with a nearly 150-year-old standard.

  Yeah speakers haven’t changed enough to make the 3.5mm connector obsolete.
  • cesarb 11mo ago
    Many new devices use a 2.5mm audio jack instead of the 3.5mm audio jack.
    • naikrovek 11mo ago
      Yes, but that doesn’t obsolete the 3.5mm jack or the 1/4” jack. It’s just a different form factor of the same thing.

  Victorian teletypes can be hooked to a serial port with a trivial adapter, at least enough to use CP/M and most single-case OS'es. Also, some programming languages have a setting to export code compatible with just Baudot characters: http://t3x.org/nmhbasic/index.html http://t3x.org/nmhbasic/index.html So, you could feed it from paper tape and maybe Morse too.

    > Victorian teletypes Wait what? There were devices called teletypes in the Victorian era (ending in 1901)? What were they doing?

      There's a recent steampunky hacked mashup called a Victorian teletype. Of more interest, to myself at least, teleprinters have a long history: * Early developments (1835–1846) * Early teleprinters (1849–1897) ~ https://en.wikipedia.org/wiki/Teleprinter https://en.wikipedia.org/wiki/Teleprinter
