I barely understood this post :)
So you owned a computer called a Sigma 6.
Xerox got into the computer business by buying SDS, which i’m not familiar with and Honeywell took over Xerox.
I’m 51. I didn’t get involved in computers really until I was in my mid 20s. Perhas SDS was a little earlier or you just know a lot more about computer companies than me.
I’m going with that answer :)
I looked up Sigma 6 and did not find anything.
I’m not even sure what Honeywell’s main business is.
I did graphics and presentations creation for investment banks for 20 years. Not too much on the tech side of things
Back in the day, the main players outside of IBM were known as the BUNCH; Burroughs, Univac, NCR, Control Data, and Honeywell.
FWIW: https://en.wikipedia.org/wiki/SDS_Sigma_series
The school added a Harris Slash 7 (24 bit specialty computer with “Unix” installed for gp computing).
My senior year, they were bringing online a DECSYSTEM-20 to replace the “Honeywell”.
Naturally, my first job out of school was programming on an 8085.
