Zenith Z-19 Terminal

    Newer Older

    The Zenith Z-19 serial terminal is equivalent to the Heathkit H-19 terminal. This is a dumb terminal. It has no local processing functions. It communicates with a minicomputer or mainframe over an RS-232 serial interface. For remote operation, this was often used with a modem. This is late 1970s, early 1980s technology. The monochrome green screen is standard 24 lines x 80 columns, text only, upper/lower case.

    Nearby is the TECO editor reference card, and a PDP-8/i reference card.

    The classic source code on screen is from www.pdp12.org/ (no affiliation).

    This was around $600 new. When I bought this, the serial port didn't work. When I called Zenith, they said I was entitled to on-site support! They sent someone out from the nearest office, about 60 miles away. He found that the baud-rate oscillator was running at the wrong speed. The motherboard was replaced, and it was good to go.

      I would like to use this photo on my website, but am not certain the type of attribution necessary or if I would simply be able to purchase it. Please email me as soon as you're able mommi_dearest@hotmail.com. Thanks! (I'm an old "framer" btw)

      Juliauna, this photo is on Creative Commons license, which means it is available for you to use. On-Line, the best attribution is a link back to this Flickr page. "Photo by Jamie Cox" would be good attribution-link text. Thanks and enjoy!

      I remember these well; although it's been a long time since I've seen one.
      Nice shot and story.
