I don't know any Unix examples, but DTSS (Dartmouth Time Sharing
System) "communication files" were used for the purpose. For a fuller

So it was with communication files, which allowed IO system calls to
be handled in userland. Unfortunately, communication files were
complicated and turned out to be an evolutionary dead end. They had
had no ancestral connection to successors like pipes and Plan 9.
Equally unfortunately, 9P, the very foundation of Plan 9, seems to
have met the same fate.

Not at all. :-) Windows Subsystem for Linux uses 9P to share files
between the linux and windows environments on the same box:

$ ps -ef
UID        PID  PPID  C STIME TTY          TIME CMD
root         1     0  0 Jan30 ?        00:00:00 /init

The u-root cpu command uses 9p, and Eric Van Hensbergen recently submitted
changes to Linux kernel 9p that boost throughput 10x. We continue to look
at ways to make it faster.

9p lives on in several corners of the world :-)

Interesting. This is now being discussed on the Multicians list (which
had a DTSS emulator! Done for use by SIPB). Warren Montgomery
discussed communication files under DTSS for precisely this kind of
thing; apparently he had a chess program he may have run under them.
Barry Margolin responded that he wrote a multiuser chat program using
them on the DTSS system at Grumman.

Margolin suggests a modern Unix-ish analogue may be pseudo-ttys, which
came up here earlier (I responded pointing to your wonderful note
linked above).

I wonder if there was an analogy to multiplexed files, which I admit
to knowing very little about. A cursory glance at mpx(2) on 7th
Edition at least suggests some surface similarities.

Another corner where I keep spotting 9P is on small embedded devices
which lack physical controls but want to give a rich interface to the
outside world without going the web-server route.

9P is also used inside QEMU, the machine emulator and ‘virtualiser’.

The machine of the DSSR/RTS group at MIT-LCS, Steve Ward's group (an -11/70
running roughly PWB1) had an implementation of a form of Perquackey:

  https://en.wikipedia.org/wiki/Perquackey

that was a multi-player game; I'm pretty sure there was a process per player,
and they communicated, I'm pretty sure, through pipes, not files - there was
certainly no IPC in that system.

IIIRC, the way it worked was that there was a parent process, and it spawned
a child process for each terminal that was playing, and the children could
all communicate through pipes. (They had to communicate because in that
version, all the players shared a single set of dice, and once one person had
played a word, the other players couldn't play that word. So speed was
important in playing; people got really addicted to it.)

Alas, although their machine was very similar to CSR's (although ours was an
-11/45 with an Able ENABLE and a lot of memory, making it a lot more like a
/70), and we shared most code between the machines, and I have a full dump of
the CSR machine, we apparently didn't have any of the games on the CSR
machine, so I can't look at the source to confirm exactly how it worked.

Hunt was the one that I thought of immediately. We used to play that
on Suns and VAXen and it could be lively.

There were a number of such games, as Clem mentioned; others I
remember were xtrek, hearts, and various Chess and Go servers.

In the annals of UNIX gaming, have there ever been notable games that have operated as multiple processes, perhaps using formal IPC or even just pipes or shared files for communication between separate processes (games with networking notwithstanding)?

Reason I ask is I've been thinking about the feasibility of such an architecture, what with perhaps a "system server" process that reads various IPC for messages from a "game" process and then internally translates those into X11 calls, OpenGL, etc. Could even be multiple servers for different concerns (display, audio, input, networking obviously).

This would be similar to a multi-threaded engine except that we're using system processes and IPC rather than threads and synchronization primitives (on some implementations, these may converge pretty heavily). An added benefit I could see would be having the one server running with the ability to arbitrate multiple games through the same pipelines. Think something like SDL but running as a server taking IPC calls to do things instead of just a library being called in the same process space. This is probably a bit more Plan 9-ish that UNIX-ish, but would be an interesting use of the system architecture.

A compelling argument for not doing things this way would be platform lock-in, as sure other operating systems would probably provide similar enough process and IPC mechanisms to achieve the same end result, but no such thing would exist on the preponderance of embedded platforms running no OS, such as cartridge-based consoles. Still, I could see such an architecture begetting clean separation of system interfacing from game logic which would then lend itself well to library-ization of the system server part in embedded cases where it has to be directly entered rather than IPC'd to from yonder process. There is then of course the performance hit of communicating between the different components via IPC rather than it all being self-contained, but as we all know, an increase in maintainability and code clarity sometimes makes a little performance and/or size hit worth it.

Anyone know of anyone doing this back before id, Unreal, and Unity cornered the game engine market?

My uncle, Richard Zopf, did extensive exploration of Mammoth Cave with Will
Crowther.  My understanding is that Colossal Cave was truly impressive in
its ability to replicate the real situations that the cavers faced,
especially given the limitations of the storage and processing abilities of
the machines at the time.  To my mind this stands well apart from the more
rudimentary early computer games which were very math/logic driven vs. the

Rich,

When you mentioned empire and Peter Langston, I was confused, but then 
realized there were probably two empires. My dad introduced me to the 
other empire (Walter Bright's) way, way back when (Original version was 
on PDP-10). It's probably my favorite text game of all time.

The c version vms-empire still builds and runs today (on my mac), these 
days it's all fancy ascii, back in the day it was pure text, IIRC:
-------------
Choose a difficulty level where 0 is easy and 99 is hard: 99

Your city is at 1797




EMPIRE, Version 5.00 site Amdahl 1-Apr-1988
Detailed directions are in EMPIRE.DOC
Cannot open saved game: No such file or directory
-------------
++.  16
+O.     R
+..  18
-------------

Bright's touchy cuz folks are always taking credit for work he initially 
did - independently of Langston, one must note :), but the story of its 
development is interesting, nonetheless:

What about Peter Langston's empire? It was distributed as object code, but

its world by having meteors smash into it to distribute the trace and heavy

"there is no way of saying 'a person can have access to a data base only
when it is accessed through a particular program'. This is, of course, a
difference between Multics and the University of Cambridge system."

The Cambridge machine was Titan.  Describes more of the history.

Best TUHS mail ever. I never knew that setuid was for moo. What other

[Douglas McIlroy]

Moo (later marketed as Master Mind) was an import from Cambridge. A
moo leader board sprang up. Maintenance of a file that had to be
written on behalf of any user posed a conundrum--how could you protect
it against false updates? Dennis's novel solution to this and related
problems was setuid, which garnered the only Unix patent.

Wumpus was my preschool kids' introduction to computing. They learned
the tricks of shooting crooked arrows faster than I learned that the
cave is always the same, with random room numbers. Only years later
did I discover by reading the code that the shape is a dodecahedron.
That fact would have helped note-taking a lot.

Wumpus predates Unix.  It was a basic game on the GE635 when I first saw it
in the mid 1960s along with a horse racing game a blackjack game.  I ran
them on the ASR 33 in my Dads office it’s what got be interested in
computers actually

Many games were on different systems and reimplemented.  david Ahl
eventually published a book called 101 basic computer games which was a
collection that he brought together from a number of systems.

HP2000, TSS/8, DTSS and GCOS as well as TOPS and later RSTS all had games
as well as Unix.

As for Moonlander, my friend the late Jack Burness wrote it as a contractor
for DEC as a demo for the GT40 and was also not of Unix origin.  Originally
it was DOS11 later RT11.   It’s an amazing piece of code - check out his 16
bit cordic integer trig routines.   He sat in the MIT library for a weekend
figuring out how to write them.  Hand simulating everything.  Went back to
Maynard and typed up his routines.   Very impressive

Rogue was Unix however but that was BSD.
