[TUHS] Re: Earliest UNIX Workstations?

As a result of the recent discussion on this list I’m trying to understand the timeline of graphical computing on Unix, first of all in my preferred time slot ’75 -’85. When it comes to Bell Labs I’m aware of the following: - around 1975 the Labs worked on the Glance-G vector graphics terminal. This was TSS-516 based with no Unix overlap I think. - around the same time the Labs seem to have used the 1973 Dec VT11 vector graphics terminal; at least the surviving LSX Unix source has a driver for it - in 1976 there was the Terak 8510; this ran primarily USCD pascal, but it also ran LSX and/or MX (but maybe only much later) - then it seems to jump 1981 and to the Blit. - in 1984 there was MGR that was done at Bellcore Outside of the labs (but on Unix), I have: - I am not sure what graphics software ran on the SUN-1, but it must have been something - Clem just mentioned the 1981 Tektronix Magnolia system - Wikipedia says that X1 was 1984 and X11 was 1987; I’m not sure when it became Unix centered - Sun’s NeWS arrived only in 1989, I think? Outside of Unix, in the microcomputer world there was a lot of cheap(er) graphics hardware. Lot’s of stuff at 256 x 192 resolution, but up to 512 x 512 at the higher end. John Walker writes that the breakout product for Autodesk was Interact (the precursor to AutoCAD). Initially developed for S-100 bus systems it quickly moved to the PC. There was a lot of demand for CAD at a 5K price point that did not exist at a 50K price point.
