Sphere Corporation

An organisation to rebuild the Sphere-1 computer

Sphere-1 Corporation

A 21st Century recreation of the Sphere-1 CPU/2 Module

About The Project

My journey into the Sphere started in March 2023, when I came across the interesting computer "Sphere 1" produced and marketed from Bountiful, Utah, beginning around 1975.

I found this reference on a Hackaday page, which led me to Ben Zotto's fantastic resource "http://sphere.computer”

With an interest in retro computing, but a very elementary electronics knowledge, I decided that I had to build one, as no-one had attempted to re-create one from scratch since the original build days.

The main issue is that the documentation is sparse, with the computers even sparser!

This is the story of how I got on, my trials and tribulations and (hopefully) in time, the results of my labours.

This initiative is organised as a series of git repositories, along with an umbrella project which should be your starting point.

Contributing

Contributions are what make the open source community such an amazing place to learn, inspire, and create. Any contributions you make are greatly appreciated.

If you have a suggestion or a resource that would help me, or perhaps you see something I've got wrong, please create an Issue.

Acknowledgments

I have to give my heartfelt thanks to Ben Zotto, who has been a sounding board for me throughout this project, answering my emails, and checking his Sphere-1 CPU/2 board to answer questions, and offering thoughts as to why things “were like they were” ! Without him, I would never have got as far as I have.
