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 Wind= ows originated there, after an epiphany I had while watching Hoop Dreams. T= rue story.

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

The sequ= ence 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 sup= er-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-t= rivial; perhaps 4MB? It seemed clearly evolved=C2=A0from the series of earl= ier terminals presently under discussion.

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

=C2=A0 =C2=A0 =C2=A0 =C2=A0 - Dan = C.
