I just got the Hardware Reference Manual on ebay for the CDC Grid
Display Subsystem (Publication No. PD82134500 September, 1969, PD-1-0).
This doesn't appear to be on bitsavers; I'm not sure but I haven't
stumbled across it in the pdf/cdc folder.  The manual is a photocopy
of an original and will be scanned for bitsavers.

GRID stands for Graphical Interactive Display, making "Grid Display
Subsystem" contain a redundant "Display" when expanded.  This looks like
an interesting system with a builtin console and enclosure containing
all the graphics processing hardware.

Has anyone used one?  Anyone got any photos?  The manual just has
diagrams.

Included with the manual was:

- a short whitepaper on the "GRID Operating System (GOS)",
    marked "Robert Gammill 9/11/70", 13 pgs.

- "GRID* USER MANUAL", John Walker, David Robertson, Robert Gammill,
    National Center for Atmospheric Research, Boulder, Colorado 80302,
    December 1971, 36 pgs.
