Warren Toomey 00c2de0292 I bit the bullet and implemented "." in the filesystem. I've changed the proto 
file to put the binaries in system. I added a few more checks to fsck, and I fixed
a few bugs in src/other/wktls.s.

Warren Toomey cbdcf268f7 More kernel notes. 2016-03-14 19:53:00 +10:00
Warren Toomey 9da0484a39 I've got init past the link, but it then dies on the open("sh") immediately 
after that. Yes, dd has to be i-num 4. I've modified mkfs7 and the proto
file to allow this to occur. I've also make link counts negative.

Warren Toomey 8b421eb27b I've commited a change to as7 to use the C pre-processor. Not sure if it's 
to everybody's taste.

Warren Toomey 947d44a681 I've used Phil's instructions to set up a build area with a Makefile.

 2016-03-10 17:02:46 +10:00

Warren Toomey d1b995e771 I've written more of mkfs7 but not tested it yet. 2016-03-10 12:46:00 +10:00

Warren Toomey 6ecf5da1a3 Updated README.md 2016-03-10 10:22:40 +10:00
Warren Toomey 2880d1b2e4 I've made a start on a mkfs tool for PDP-7 Unix. So far I have the routines 
to build the filesystem, but they are not tested. I need to add code to
parse the "proto" file, whose syntax is based on the 6th Edition proto file.
I also need to dump out the filesystem image.

Warren Toomey c65a5587fb Comments to kernel files by Phil. 2016-03-09 06:45:44 +10:00
Warren Toomey 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!
 2016-03-08 20:05:14 +10:00
Warren Toomey 77505026ae I made my own opr.s with definitions for . and .. and now the native 
PDP-7 as can assemble cat.s. I haven't checked the output yet.
 2016-03-08 19:03:28 +10:00
Warren Toomey 10a0983cc4 as.s typo. 2016-03-08 18:47:14 +10:00

Warren Toomey 5877df91e8 Finally, date works, and I've also written a decimal conversion routine 
in sys/other.

Warren Toomey cfafcad963 a7 is updated with Phil's stdin reading patch. I've written a few more

line) in src/cmd/as.s.
 2016-03-07 16:17:57 +10:00
Warren Toomey 42636a83e3 Added ls.1 manual. 2016-03-07 06:26:15 +10:00

Warren Toomey 10befe6cc4 Warren's ls now has -l argument which prints out lines in long format! 2016-03-04 21:56:46 +10:00
Warren Toomey c8ac75f371 Added a dprintf which I forgot. 2016-03-04 15:37:04 +10:00
Warren Toomey 6f3008e8bd I've gobe for my own mul algorithm for now, and it seems to work for small 
positive integers, but it probably needs fixing.
 2016-03-04 15:29:37 +10:00
Warren Toomey 807fb56d35 I've added the idiv and mul instructions which are needed by the original PDP-7. 
However, these are completely untested at the present!
 2016-03-04 15:15:57 +10:00
Warren Toomey 575163a35a I wrote a test for the octal conversion routine, and I updated ds.s 
with the comments that I wrote for the octal conversion.
 2016-03-04 14:34:25 +10:00
Warren Toomey 5b9ecc343d I didn't mean to check the stuff in bin! 2016-03-04 14:17:42 +10:00
Warren Toomey e928dbf7b6 Added the bin directory for assembled programs. 2016-03-04 13:41:16 +10:00
Warren Toomey 218e060a55 I've added the seek() system call to a7out. I've also added some heuristic code 
to detect if file output is "binary" or ASCII and to write the file correctly.
Mind you, the heuristic can fail :-( The original cp can now copy ASCII and
binary files.
 2016-03-04 13:39:38 +10:00
Warren Toomey 154039a9ee Merge remote-tracking branch 'origin/master' 2016-03-04 13:05:04 +10:00
Warren Toomey 451a58fc58 I've added code to detect binary PDP-7 files to a7out. This is needed 
for doing the seek() and tell() syscalls which are next to do.

Warren Toomey d3f6924a9c I fixed a few typos in ds.s and I made a pretend llss instruction in a7out. 2016-03-03 19:46:34 +10:00
Warren Toomey d33ce4c69f Based on the details of the directory structure that Phil found, I've 
modified the a7out and the wktls.s program to reflect this.
 2016-03-03 16:35:05 +10:00
Warren Toomey 336e0c1118 Updated the top-level README with current details. 2016-03-03 15:38:02 +10:00
