- UNIX V6 on the Supnik simulator:
- --------------------------------
- This directory contains tape files for the Supnik simulator and
- accompaning README files, which I produced when preparing an OS
- course at the Berufsakademie. Further it contains C-sources of two
- commands (enblock.c/deblock.c). These commands prepare a tapefile for the
- simulator (enblock) and produce a plain file from a simulator
- tapefile (deblock).
-
- The Supnik simulator can be obtained from:
- ftp://minnie.cs.adfa.edu.au/pub/PDP-11/Sims/Supnik_2.3/sources/
- I used the sim_2.3d.tar.gz tar ball.
-
- This directory contains a *.README and *.enb files with the following
- basenames:
-
- ctable: A bug in the input table for the C-compiler code generator is fixed.
- ctime: Some y2k related changes to V6.
- dcheck: Bug fix and enhancement of dcheck.
- dist: The V6 distribution tape: dist.README explains how to install
- and setup UNIX-V6 with the simulator. The file dist.enb is missing
- for copyright and space reasons, you have to prepare it yourself.
- (see enb.README).
- dotdot: Kernel enhancement: If in a root directoy of a mounted filesystem,
- let ".." mean the parent of the mount point, not the root directory.
- enb: Conventions and usage of .enb files. Explains how to
- prepare tape files for the Supnik simulator and tells you
- how to prepare the V6 distribution tape.
- ludiv: Derivation of a double word unsigned division algorithm, which is used
- in ctime. (no corresponding .enb)
- man: The man command, which was missing from the distribution, and some
- changes to make V6-nroff output readable on an xterm.
-
- So enb.README and dist.README are the next files you should read.
-
- If you have questions or find bugs or whatever, mail to
- helbig@informatik.ba-stuttgart.de
-
- Last but not least I thankfully acknowledge the work of the people
- who talked SCO into offering the ancient-UNIX source license, who collected
- the old distribution tapes and run the PUPS Archive. And of course I thank
- Bob Supnik for this great simulator!
-
- Have fun,
- Wolfgang
