New port of ITS RP06 filesystem image for KLH10 PDP-10 emulator

	New port containing an ITS RP06 filesystem image for KLH10
	PDP-10 emulator.  Now's your chance to see firsthand what
	was happening at MIT in the 60s through the early 90s.  Run
	the original versions of Emacs on TECO and Maclisp, etc.

+Consider adding firewall protection for the KLH-10 emulator before
+ever running it.  See @PREFIX@/share/doc/its/pubits/adm directory for
+samples.
+
+To setup the emulator you must run the its-user-install(1) command.
+It takes no arguments.  It is best to run it as a regular (non-root)
+user.  Once that has been done to start ITS run the its(1) command.
+It also takes no arguments.
+
+The first time the ITS boots it will not know the time of day.  ITS
+will display this message:
+
+The time could not be set because:
+No host responded.
+It will be necessary for someone to set the time
+manually by logging in and running :PDSET.
+
+Tell ITS to activate the apex procedure, DDT, by typing a Ctrl-Z.
+When you type that you will see:
+
+KN ITS.1647. DDT.1545.
+TTY 0
+You're all alone, Fair share = 0%
+
+(ITS does not know the date, so messages cannot be reviewed right now.)
+
+Then run PDSET by typing (colon and all)
+
+:pdset
+
+ITS will suggest that you log in but you don't have to.
+
+(Please Log In)
+___002 PDSET  IOTLSR  
+
+Now enter the time and save it.  First the century:
+
+20C
+
+Next the YYMMDD:
+
+020219D
+
+Then the HHMMSS (try to time it so you have some lead time because it
+will become active when you save it.)
+
+235115T
+
+Now save the time:
+
+!.
+
+Now exit PDSET
+
+X
+
+You will have no feedback from the exit operation except that new
+commands will be echoed in lower case.  Now bring down ITS so you can
+start it without being root:
+
+:lock
+(Please Log In)
+ LOCK.154  
+_
+
+the _ is a prompt, do not type it.  Type
+
+5down
+
+LOCK is very picky about typos so be careful.  It does not need the
+Enter key so don't use it.

+DO YOU REALLY WANT THE SYSTEM TO GO DOWN?

+$ 
+
+ITS uses DEL for erasing characters.  ITS defaults to dumb hardcopy
+terminal settings.  This is a pain so you want to configure ITS to
+use something nicer.  ITS knows about VT52.  If you are using xterm
+from XFree86 you can get into VT52 mode by running a script like this:
+
+#! /bin/sh
+
+awk 'END {printf "%c[?2l", 27}' </dev/null
+
+From ITS run
+:tctyp vt52
+
+On your VT52 mode terminal emulator.
+
+An alternative is that you can use vt100 mode via the CRTSTY program
+which is a bit like window(1) in that you end up on something like a
+pty but only one full screen window is available and it does terminal
+emulation on it.  You will be automatically logged in a second time on
+the same terminal as a crufty side-effect.
+
+:crtsty vt100 speed 9600
+
+Run :info and look at the introductory information about the
+filesystem.  I did not find that it covers directory operations very
+well so here is what I have found out.  ITS does have a process tree
+(try the PEEK command) but does not have a directory tree.  There is a
+Master File Directory MFD (try DSKUSE * or DIRED and then MFD.  Use
+"Q" to quit after either of those.) and User File Directories UFDs one
+level deep only.  The only way to remove a directory is to delete its
+contents and run the salvager. The salvager is the ITS equivalent of
+fsck and will automatically be run at boot time.  To create a new
+directory provide certain options to the open UUO (ITS equivalent of
+system call; try the DOC UUO command.)  Since the PRINT command calls
+the open UUO you can create a directory using print:
+
+:print ..new. (udir) dirnam;
+
+Where dirnam; is the name of the directory to be created.  Directory
+names are limited to six characters.
+
+Missing from this ITS distribution is the INQUIR database.  It
+contains user information.  There were too many personal details in it
+and no one has been able to scrub it so it was left out.  This means
+you cannot have a complete user account yet.  The best you can do is
+to pick a user name and make yourself a directory with that name and
+put a login script in it.  In this example the user "user" is created:
+
+:login user
+:print ..new. (udir) user;
+:emacs login user
+[add startup code like ":tctyp vt52" and ^X^S to save ^X^C to exit]
+
+You log out with <ALTMODE><ALTMODE>u which is [Esc][Esc]u and
+represented in the documentation as $$u
+
+The ITS equivalent of $PATH is implemented by scanning all
+directories for files for files with TS as the first name and
+the second name set to the command you issued.  By convention
+most commands are in the SYS; SYS1; ... SYSN; directories.
+ITS supports symlinks via the LINK command and TS name is often
+a symlink.
+
+ITS equivalent of job control works by typing ^Z to interrupt the
+current program.  To get back to the DDT prompt "*" use $^K
+
+Don't like DDT as the shell?  Try MONMOD to use monitor mode where the
+colon is printed for you.  DDTMOD gets you back.  Or try SHELL to
+bring up a UNIX-like shell.
+
+Zork was developed in MDL (muddle) on an ITS system but apparently it
+suffered from being too popular.  Try the ZORK command to see what
+happened.  A scrap of MDL source code is left (:find @muddle) but I
+don't know how to MIDAS it.

+This is an image of a PI (Public ITS) filesystem that can be booted on
+the KLH10 PDP-10 emulator.
+
+The emulator image is about 45MB compressed and 170MB uncompressed.
+The installation needs to have a minimum of 45MB in ports/disfiles
+plus 45MB in the installation directory which defaults to
+/usr/local/share/klh10-ks-its.  That's about 90MB total but "make
+distclean" will delete 45MB leaving you with only 45MB.  After "make
+install" you must run the "its-user-install" script as a regular user
+to install an uncompressed 170MB RP06 filesystem image and setup
+emulator support files.  Additional 170MB RP06 filesystem images
+may also be installed.
+
+For more information about ITS see WWW: http://www.its.os.org/
