The paper by Melinda Varian sounds interesting.

Here is the quote from her very interesting paper ( I strongly recommend to read at least the beginning of this 73 pages paper -- it provides new insights into how two most interesting operating system Unix and VM/CMS were influenced by Corbato's CTTS and MIT Multix project)
As of 2021-03, the link http://pucc.princeton.edu/~melinda/ is stale, but I found the paper (167 pages)
VM AND THE VM COMMUNITY: Past, Present, and Future by Melinda Varian, April, 1991
on http://www.leeandmelindavarian.com/Melinda/neuvm.pdf

This repository contains a port of the "Ritchie C compiler" to the TI990 series processors, in particular the 9995 and 99105 chips. The port is currently fairly complete; only floating point operations remain unported. Other tool chain components (assembler, linker, etc.) are also provided.

The long term goal is to run ancient unix on these chips. As a first stepping stone on that journey, a port of the original 1983 version of the Xinu system has already been completed. The source for that is also in this repository.

but the articles about Turing look interesting too.

Settings for emerge, smerge sounds interesting too.

The blog has a number of interesting articles, which I only have browsed so far.
