IGS? Two colors? Don't recognize that.
There's the 6000 console
(DD60), very expensive, requiring a dedicated processor to feed it,
and limited to uppercase text only plus very small amounts of
graphics (a dot at a time, 3 microseconds per dot).
IGS (Interactive Graphics System) was the generic term for the
Digigraphic 200-series stuff. The consoles came in various flavors, but
the best ones were the big, flat-surface jobs.
The display processor with these things was pretty large; someone once
told me that it resembled a 1700 more than anything.
A lot of fun to fool with.
