Yes, me in example :-). I wonder wether you could give them to dmr to be
placed just at the side of the v7 docs, or wether you could put it
into the archive?

 > First README:
 > 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.
