Very old, but precious UNIX documentation from the 1970`s. These would be very interesting reading for someone interested in UNIX.
1972 UNIX programming manual.
https://www.tuhs.org//Archive/Distributions/Research/1972_stuff/unix_2nd_edition_manual.pdf.
Tmg compiler-writing language manual.
https://www.tuhs.org//Archive/Distributions/Research/1972_stuff/tmg.pdf.
UNIX Programmers manual November 1971.
https://www.tuhs.org//Archive/Distributions/Research/Dennis_v1/UNIX_ProgrammersManual_Nov71.pdf.
UNIX Kernel Subroutine Descriptions March 1972.
Intro on how manual pages are laid out in UNIX. 1971.
https://www.tuhs.org//Archive/Distributions/Research/Dennis_v1/manintro.pdf.
Setting Up Unix – Seventh Edition. Setup documentation for installing UNIX.
https://www.tuhs.org//Archive/Distributions/Research/Documentation/v7_setup.html.
What is UNIX? This documentation explains what UNIX really is and what it can do for you.
https://www.tuhs.org//Archive/Distributions/Research/McIlroy_v0/UnixEditionZero.pdf.
PDP-7 and PDP-9 to data-phone interface explained.
https://www.tuhs.org//Archive/Distributions/Research/McIlroy_v0/02-hw.pdf.
Version 7 kernel source code. This would be fascinating for a UNIX researcher.
https://www.tuhs.org//Archive/Distributions/Research/Nijmegen_v7/.
All of this documentation is well worth downloading and reading for any UNIX researcher, who is interested in very old UNIX code and functionality. This is from a time when real men used time sharing systems and serial terminals. Not the fancy 1080p screens, Nvidia cards and terabyte HDD storage we have today.
There is also a very old 70`s copy of the UNIX cp utility as source code.
https://www.tuhs.org/Archive/Distributions/Research/1972_stuff/oldcp.c.
But I could not get this to compile on a modern Linux.

So better to install an old UNIX and compile it on there instead.
