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.

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.
To use this version: cd build; make alt; make altrun

I've split the cmd and others Makefile rules out to individual utility rules,
...
so that we don't keep building binaries for sources that have not changed.

I changed the Makefiles so that I could make run without rebuilding
...
everything. This is mainly because I often boot the system several times
in a row when debugging, and I didn't want to have to build everything
just to reboot the system :-)
