Demonstration of a Sphere microcomputer from 1975

Demonstration of the setup and built-in functions of a a Sphere computer from 1975. This was a modular, very early microcomputer from Salt Lake City. It was based on the Motorola 6800 microprocessor. In this video we look at the most basic configuration, just a CPU and CRT board, and we connect them up without the standard case, directly on the desk. Then we try out at Sphere's Program Development System (PDS) firmware, with its editor and mini-assembler. The Sphere computers were sometimes referred to collectively as the "Sphere 1" computer. Watch my presentation at the Computer History Museum in 2022 about the history of Sphere computers, the company, and the community:    • VCF West: Sphere 1: The First Modern Micro...   Info on Sphere and this project, including documents, images and software information. https://sphere.computer (Sign up there for email updates on the book, etc!)
