youtube video of a runnning XDS Sigma mainframe with lots of nice peripherals

[Lee Courtney]

Hi Pierre,

Sorry forgot to address this in my original email...

"There's also a Data General minicomputer and Honeywell mainframe equipment.
Can anybody identify the Honeywell stuff? It's Level 6000 style, but
it's strange to me that there seems to be just this one cabinet along the
rest of the XDS equipment. Maybe a Datanet option?"

When Honeywell bought the Sigma mainframe business from Xerox in 1975 it
agreed to continue support and provide upgrades. One of these was
interfacing various peripherals and upgraded memory. The Honeywell box
George had connected to the Sigma-9 was a solid state memory. It was not a
stand-along Honeywell computer, just semiconductor memory rather than core
memory that was originally used on the Sigma-9

Yes, he did have a DG minicomputer in the room also. I never saw it run.
