My system is a Southwest Tech 6800 with 36k of memory, dual mini floppies, a Hazeltine 1500 video terminal, and a Trendata1000 Selectric terminal. The small box on the disk drive is my low cost modem.
This photo is from the Northwest Computer News, July 1978.
The Trendata 1000 was an IBM Selectric terminal based on the IBM 2741. These could be used for creating Texas Air National Guard memos.
Here is another photo from 1981.
