These seem to all date from the '80s or later. Quite a few earlier systems are available to run under simulation -- including historically interesting ones for the PDP-10, PDP-8, and other DEC hardware. Here's a starter list, from the SIMH project: http://simh.trailing-edge.com/software.html http://simh.trailing-edge.com/software.html

I’m big into retrocomputing, particularly retro telecom and odd enterprise/business systems. (Have me an SGI and DEC Alpha right now, and hope to get a VAX machine and many other things in the future). One particularly interesting system to me is the HP 3000[0] 2100and 1000 series[1] of real time computers (which had a number of generations and name changes, and ofc as it’s an HP machine, now lends its name to printer). I plan on buying one, though it’s rather expensive as most of the machines I have left on my list are, so in the meantime I figured I play with a SIMH emulator. These things ran a fun little OS called RTE or real time executive and man, I’ve never had such a hard time understanding an OS. I’ve only played with it briefly and am not very familiar, documentation is archived, but a bit hard to follow for me sometimes. As far as I know, it dates back to the 60s/70s with it being updated through the series computers all the way through to the 90s. I’m not a huge *nix fan in a greater world of operating systems, but I gained a newfound respect for UNIX and it’s descendants after using this operating system from around the same time. Though perhaps the real time nature of the system adds to the foreign feeling. I’ve got a screen grab showing me following a basic tutorial, running some program, and then using it to list process and a few other things regarding storage I don’t understand yet: https://imgur.com/a/iqYQdQ8 https://imgur.com/a/iqYQdQ8 [0]https://en.m.wikipedia.org/wiki/HP_3000 https://en.m.wikipedia.org/wiki/HP_3000 [1]https://en.m.wikipedia.org/wiki/HP_2100 https://en.m.wikipedia.org/wiki/HP_2100

  The HP3000 platform family (classic and later RISC) is very different architecturally from the HP2100/1000 family and runs a totally different, much more friendly OS.

    Ah, for some reason I thought it ran RTE as well. I think maybe because the 3000 and 2100/1000 both had SPL compilers and I’ve never seen that on any other arch.

  I spent five years living in the HP 3000 world around the year 2000. I feel some nostalgia for the operating system[0] I am aware of one software package for the 3000 (Qedit) which was updated as recently as 2019[1].
