Dunfield 6809 Portable © 1983 Dunfield.
Homebuilt computer made around the 6809.
In 1983, Mr. Dunfield designed a little 6809 based computer system, including the hardware and all softwares. The operating system was called CUBIX. This system was designed to give high functionality with minimal hardware. It itself occupies the better part of an 8K ROM, and provides a nice file system, a command line shell (including a good selection of build in commands and script/batch files), and over 100 system calls/services.
