What ever happened to Tandem and NonStop OS 2067

I remember taking a DCL clbutt back in the late 80s, early 90s. Did DEC teach Unix, too?

The only DEC system I ever saw that didn't run a DEC OS was two PDPs in OS clbutt! The point was to learn how to write your own OS. I still want to see figures that claim 80% of VAX owners didn't use VMS.

My point is that DEC DIDN'T want you to write your own, they wanted you to use their OS. Wasn't there some sort of wavier you had to sign stating that you were on your own if you didn't use a DEC-supplied OS?

Tight coupled HW and SW. DEC may have been looser than IBM, but by the time DEC went under they were not as loosely coupled as the rest of the market. Who was making a living as a third party OS writer writing DEC system OS code? DEC's whole "open" push with OSF-1 was too little too late. And THAT is what I have been saying from the start of this thread.

If DEC was as open as you claim, then why even claim to be "open" with the Alpha in the first place? Why not claim to CONTINUE being open?
