94fd5d49e0 I've restructured the alternative version of PDP-7 Unix so that the source code is now in src/alt. All the files in src/sys and src/cmd are only annotated versions of the files in scans/. The build/Makefile has been updated so that it can build the original PDP-7 Unix or the alternative version. Phil has fixed the Graphics-2 code, so that there is no need to have any #ifdef code in the original kernel. Warren Toomey 2016-03-21 16:01:36 +10:00
f63ad33d10 This is the beginnings of a alternative version of the PDP-7 Unix system which corresponds to a later development point, around mid-1971, where the system had lost the "dd" directory and gained . and .. entries. This is close to the system as described in http://www.tuhs.org/Archive/PDP-11/Distributions/research/McIlroy_v0/UnixEditionZero.txt except there are no pathnames.
