The Gnot had a 68040 (which had an MMU that paged properly) and an INCON interface, which was a kind of Datakit for the home. Twisted pair. Half a megabit if I remember right, but I probably don't.

Two bits per pixel. The "render extension" in X Windows originated there, after an epiphany I had while watching Hoop Dreams. True story.

The MIPS machine you refer to was called a Magnum, made by somebody for Microsoft as a porting engine for Windows to non-Intel.

The sequence is thus Jerq, Blit, DMD-5620. DMD stood for dot-mapped rather than bit-mapped, but I never understood why. It seemed a category error to me.

The first time I saw a terminal of that lineage, it was a gnot (Gnot? GNOT?) running Plan 9; this would likely have been 1993 or 1994; I was in high school and visited a college-student friend of mine who was interning at the labs and Dennis Ritchie had one on his desk. As an aside, he kindly spared me a few minutes; I confess I was too star-struck and embarrassed to ask him to autograph my copy of K&R that I had brought along. Dennis was a kind, humble person and I was always quite struck by that in comparison to some other academic and industry super-stars I've met.

Anyway, my question is what was the evolutionary story of the gnot? I recall being told that it had a 68020, a datakit interface, and some amount of RAM that was small but non-trivial; perhaps 4MB? It seemed clearly evolved from the series of earlier terminals presently under discussion.

And the next step in the evolution was a MIPS-based terminal; I can't recall the name, though.
