[inforoots] CDC operating system for CDC 6000 series systems

[Brian Knittel]

We used a homegrown OS called "BKY" at Lawrence Berkeley Laboratory 
on a CDC machine that was retired in the mid 80's. I THINK it was a 
6600. Maybe it was a 7600. But, hmm, I thought LBL had the 6600, and 
Livermore had the 7600. It's irritating that I can't remember these 
details now.  

I do remember that the day after it was decomissioned, I saw its two-
round-screen operator's console and other cabinets sitting outside in 
the rain in the lab's salvage yard. I remember feeling shocked that 
it was being treated with such disrespect, after all the work that 
machine had done to advance particle physics.

Down the hill, the UC Berkeley campus had a CDC 6400 that was running 
either BKY or SCOPE. Which OS used the 6-7-8-9 card as an end-of-job 
marker? BKY or SCOPE or both?
