[Simh] Fwd: V6 on PDP-11 and 4.0BSD on Vax - automated installs now available

[Tom Perrine]

I had a few goals for this: get v6 running, learn about SIMH, learn about
GCP and set it up so that anyone could use it easily, no matter what OS
they use for their "home" system.

I think that I got 3.5 of the 4 - basically if you are running Windows,
you'd need to spin up a Linux host, either in a VM or in the cloud or even
as a Raspberry Pi. Other than that, I achieved the goals of V6, SIMH and
GCP.

I'm not a container person (yet), I'm rather old school, as my first UNIX
was PWB. I'm interested in containers, so I might revisit this, or I might
try to get 4.2BSD running in a container.

These are all steps towards the actual end goal, which is running the A1
candidate security kernels KSOS-11 and KSOS-32. Those are projects that I
worked on and I have access to the source code. But they aren't self
hosted, needing PWB and 4.2BSD for the system generation using custom
Modula and Modula-2 compilers.

Thanks for the Docker suggestion. It's a way that I hadn't considered, and
it would have some advantages over what I've done so far. Honestly, getting
the proper commands injected into SIMH and into the running UNIX systems
was the hardest part.  There are some good cookbooks out there that I
essentially automated.

Cheers,
