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.
