Summary
DescriptionZenith Z-19 Terminal.jpg |
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 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. |
