Other 6809 Computers
There were other 6809-based single board computers that appeared around the time
I was finishing the design of the ST-2900.
Some were quite large and included video circuitry and other features. But the
Peripheral Technology PT-69, which was only 50% larger than my CPU board, was
probably the main competition for the ST-2900.
6809 Single Board Computers that could run FLEX and/or OS-9:
If you have information on any other 6809-based computer that included at least 48KB
RAM, one or more serial and parallel ports, and a floppy disk controller, on only 1 or 2
boards (that did not require a backplane/motherboard), and that was available before
September 1984, please let me know, so I can add it to this
page.
Other interesting 6809 CPU boards and computers in the past:
