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.

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.

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

3be45d4383 Moved opr.s to src/other as it is not a proper utility and wasn't in the scans. 2016-03-09 06:48:37 +10:00
Phil Budne
66a8168228 as.s starting to work! Add ops.s 
replaced "sys write; 1; 0; 4" with "sys write; 1: 0; 4"
  In the scan it REALLY looks like three semis, but that makes NO sense!

286acea85b With src/cmd/as.s modified to use als (because a7out is broken) and removing 
the definitions of . and .. from wktopr.s, I can now assemble cat.s with
the PDP-7 as and execute the resulting a.out file!

cfafcad963 a7 is updated with Phil's stdin reading patch. I've written a few more 
utilities and modified the v1 man pages for them. Fixed a typo (missing
line) in src/cmd/as.s.

lcase.b is a filter program that converts upper to lower case, tabs to
spaces, and removes form feed and carriage returns.

714de5a7e1 I've added a single-step mode to tools/a7out and rationalised the debug output. 
Some small changes to src/cmd/cat.s and wktcat.s to reflect the correct number
of arguments to open. Typos fixes to src/cmd/cat.s.

63223cfa7c Now that the PDF files have been transcribed and scanned in, I've moved 
copies of them over into the src/ area so that we can add comments and
make other changes, while keeping the original OCR'd ones intact.
