I’m wanting to get into the game of Visualizing vintage operating systems like Xenix and System IV,V and VI. I’m not really interested in the retro hardware. I’m instead Moore interested in the software side of vintage computing.
I’ wouldn’t shy away from playing around with variants of DOS such as IBM PCDOS MS DOS and others.

There’s a blogger named Jason Stevens (a.k.a. “neozeed”) who has
a Web site: https://virtuallyfun.com/
. . .that has a lot of articles going back to the middle of 2007
that may be of interest to you.
Of course, there are many specialty emulators and their associated
communities – Hercules for IBM 370 and its succesors;
SimH for DEC computers primarily, but there are others as
well, some of them forks (like Multics); Qemu for more
modern architectures like Sun Sparc (Solaris), IBM Power (AIX),
HP PA-RISC (HP/UX), and even RISC-V; MESS/MAME (primarily games,
but some “serious” machines from the early micro era).
