It is assumed the reader is already somewhat familiar with contemporary Unix-like systems.//Note to SDF MetaARPA members: I am not an expert on any of the historical systems and it's unlikely I'll be able to investigate all of them in sufficient depth, so feel free to check out this document and enhance it with your own insights and discoveries, or features or tricks I have missed. — papa//==== Notation ====
  | "command" | Command name or other fixed syntax;enter as-is. |
  | //place-holder// | Place-holder for user-supplied value. |
  | [//item//] | //item// is optional. |
  | //item// … | //item// may be repreated one or more times. |===== UNICS (Version Zero) =====Release: Summer 1969\\  Platform: PDP-7The operating system hacked together so Ken Thompson could play //Space Travel// after Bell Labs withdrew from the Multics Project. The new operating system was named as a parody of “Multics”.This version of the operating system has a file system, a shell, a text editor, an assembler, and very little else.
  * **commands available**: as, bc, cat, chdir, chmod, chown, chrm, cp, date, ln, ls, mv, stat //ken writes//
       here is sme stuff..
       adm and apr submit jobs to the central
       batch processing machine (ge-635 gcos)
       i only remember a command to submit a print
       job. the pdp-7 had no printer. actually, there
       was a newer print job that got the printing
       done by rejecting the batch job for some
       trivial syntax error. printing would cost.
       job rejection was free.
       sys save generated a core file that,
       when executed, would continue after the
       sys save. it was used for breakpointing
       long jobs and for jobs that had a lot of
       initialization so they would start up faster.
       a note; this unix did not have a hierarchial
       file system. there were only a fixed number
       of directories. each was linked to by the
       directory directory dd. to get to another
       directory, you did
       chdir dd
       chdir dir
       but the chdir command would take
       multiple arguments so the above is
       chdir dd dir
       if you ever unlinked your link to dd,
       you would be cut off.
       later dd became .. meaning up. one could
       not reference a file in another directory
       directly. thus you had to link to it by a local
       name and then reference through the local
       name. this
       link; sys; x; y
       made a local link y to the file x in directory
       sys referenced off of dd. does that clear
       up some of the naming confusion.
       i will work on some of the other stuff you
       mention. some of it sends gravity waves
       through the cobwebs, but nothing specific.

  Logging on to the "ken" or "dmr" account - password is the same as the username=== Notes on the TELETYPE === Yeah, remember you're on an ASR33 Teletype - you can only go forward!\\ //(Special thanks to Dan Cross and Mary Ann Horton for discovering and demonstrating these at UNIX50)//
  * @ = kill's the current line
  * # = erase character
  * } = intr (equiv to ^C)
  * ^D = EOT (used to close a file) === Notes on the Commands ===
  * //bc// - not the calculator, but the B compiler.
  * //ls// - supports the -l option which displays inum, type[dls]/umode/omode, nlink, uid, size and name - //warren toomey//
  * [[https://sdf.org/tutorials/man/unixv0|Manual Pages for UNIX Version 0 for the PDP-7]] (//special thanks to wkt and tuhs//) There is no concept of filesystem paths or '..' in Unics 0. It is also important to note that 'dd' is a Multicism and stands for\\  the "Directory Directory". This concept will become '/' or 'root' in Version 1 UNIX. The shell searches two locations: 'system' and '.'\\  However, '.' must be linked with the following command:
  * //ln dd userdirectory .// - links 'userdirectory' in the 'directory directory' to '.' aka the current directory.
  * //ln dd dd udd// - creates a new link named 'udd' to 'directory directory directory directory' in the current directory. (You'll need to do this for the next example)=== A **Hello, World!** written in B for Unics Version 0 ===
  * login as //dmr//, //dmr//
  * //ln dd dmr .//Now you can type //ls// and see the contents of the directory
  * The file //hello.b// contains:
    @ cat hello.b
    main $(
     write('He');
     write('ll');
     write('o,');
     write(' W');
     write('or');
     write('ld');
     write(!*n');
    $)
  * //bc hello.b hello.s// # bc will compile hello.b and produce hello.s
  * //as ops.s bl.s hello.s bi.s// # as will assemble hello.s along with the standard libraries and produce an a.out
    @ a.out
    Hello, World!
  === Notes on using 'as' under Unics Version 0 ===
  * //ops.s, bl.s and bi.s// Opcodes and System Calls - must be included in any assembly For the UNIX 50th on 10-Jul-2019 SDF held a **//B Language//** challenge on the DEC PDP-7 running UNIX Version 0 under simh.\\  A herd of hackers gave it a go over the course of 2 hours and in the end there were 4 that put in best efforts:
  * Karl Koscher (@supersat) - WINNER
  * Dan Cross - Runner UP
  * Mary Ann Horton - Valiant Effort
  * Seth Morabito (@twylo) - Flailing Attempt (awarded with a '?') Karl's effort implements a somewhat ROT1 and was the only working example of TTY IO. The code follows:**fdip.b**
    main $(
     auto c;
     while (1) $(
       c = read();
       write(c + 1);
       flush();
     $)
