What I'd like to see is a community effort to make a new OS that does what
needs to be done without worrying about being compatible with something that
currently exists.... Sure, it may not have a lot of software available...

It was thus said that the Great Eric Dittman once stated:
Well, AmigaDOS has processes, threads, semaphores, message ports,
messages, preemptive multitasking, multiple file systems and long file names
(on such filesystems that support that). It's not multi-user so it lacks
file permissions but it's a single user OS anyway. What else do you need?
-spc (AmigaDOS was one of the more fun OSes to program for ... )
Two examples of the results of that... AmigaDOS,
BeOS. There are others.
AmigaDOS is different, but I don't know if it has all the features
I'd like. As far as I know, BeOS tries to be somewhat Unix compatible.

Every native filesystem has got at least thirty character filenames. More
modern ones have bigger limits. Still, thirty characters is long to most, at
least until you start playing with MP3 files. =)
BTW, if you really want some multiuser stuff, there was a mufs update on
Aminet as late as yesterday. =)

It should be pointed out that AmigaDOS is just the DOS of AmigaOS. As we
established several months ago, AmigaDOS is very much a clone of the Tripos
system. And it was programmed in BCPL. Unlike the rest of the OS, which is
M68k assembler and C. Which caters for some funny acrobatics when the DOS
expects BCPL structures and the OS (as well as the programmer) would like C
structures. Originally, there was another DOS called CAOS under development.
It was more UNIX-like and more compatible with the OS, but since the
development dragged on, a quick port of Tripos was brought in as a
replacement. Frankly, I think it's for the better. As a non-programmer end-
user, it's really comfortable.
Here's a URL: http://www.thule.no/haynie/caos.html
All this elaboration was just to ask: Was it really so fun programming for?

Amiga: (noun) The most technologically advanced computer that hardly anyone
cares about.
Use in sentence: "I wanted to buy an Amiga for its low price and great color
graphics, but everyone else seems to be using IBMs or Macintoshes. So, to
remain compatible with the rest of the world, I spent three times as much on a
Macintosh and got only half the graphics capability of an Amiga."

Well, we once wanted memory protection, but seeing that all
the above was based heavily on the fact that any process could poke
into any other memory, it was tough. :-)

AmigaOS is a zero-copy system, which makes it quite fast. Inter-process
communications are simply done by passing pointers instead of copying the
required data. Efficient but hardly secure. =)

Personally I'd say that BeOS tried to be a
combination of AmigaOS and UNIX.
Note, I said tried, because they're either dead or dying, and AmigaOS is
more alive than they are.
BeOS, as well as the Be hardware, are both pretty cool. I
don't think the OS ever got outside the realm of just being for
tinkerers though since it had few real applications. I never did
have any luck installing it on real Pentium machines at home though
and unfortunately it's not supported as of yet by Virtual PC.
