I agree WAITS gets very little attention, particularly in relation to
the great number of things pioneered at SAIL.

I'm involved making emulators for some of the hardware.  SAIL started
out with a couple PDP-1 timesharing systems with vector displays from
Philco.  But that's almost a pre historical era.

The PDP-6/10 started with another vector system from III.  It could
support up to 12 displays, but only ever had 6.  A raster display system
was added in the early 70s.  It must have been one of the very first
bitmapped display systems.  It came from the Data Disc company and used
disk for storage.  It was dual ported: the computer could write data,
and the displays could read.  64 displays were supported.

The III and DD displays used the SAIL keyboard which introduced the META

The Data Disc displays and SAIL keyboard heavily influenced Tom Knight
at MIT to make a similar system for their AI lab PDP-10 running ITS.
