Warren Toomey from The Unix Heritage Society (TUHS) posts: http://minnie.tuhs.org/pipermail/tuhs/2016-February/006622.h... With the link: http://www.tuhs.org/Archive/PDP-11/Distributions/research/Mc... From the Readme: The structure of the kernel source code is very similar to that of the 1st Edition Unix scan at
http://www.tuhs.org/Archive/PDP-11/Distributions/research/Dennis_v1/PreliminaryUnixImplementationDocument_Jun72.pdf
Here is what I can glean from the files:
01-s1.pdf contains the kernel source divided into sections S1 to S9
02-hw.pdf has hardware details of the PDP-7
03-scope.pdf has information about the PDP-7 scope
04-cas.pdf seems to be a user-mode program that uses the PDP-7 scope
05-1-4.pdf user-mode programs: adm, ald, apr, as
06-5-12.pdf user-mode programs: bl, bc, bi, cat, check, chown, chmod, cp, chrm
07-13-19.pdf user-mode programs: db, dmabs, ds, dsksav, dskres, dskio, dsw, init
08-rest.pdf user-mode programs: ed. Also at the beginning some B code (?)
