A 21st Century recreation of the Sphere-1 CPU/2 Module
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 organised under an umbrella organisation of Sphere
-Computer.
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.

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.
