Very cool, always nice to see OpenBSD growing into more platforms. Anyone have any successes with this platform to report to us?

computers are designet for stability and numbercrunching, the System 300 alone has 1xM88100
CPU, 4xM88200MMU and a CP (M68020) for each I/O board.

Perdon me, but numbercrunching @ 25Mhz, I don't buy it. Today's desktop is clocked @ 3Ghz, now that's what I call a numbercruncher.

Hz doesn't say hell of a lot, and just comparing 25 mHz ...
By Anonymous Coward () on
They're just nice SBCs, very interesting systems with one of the sleekest RISC CPUs (88100/110).
More lame info, though somewhat incomplete:
www.doorslam.net/m88k .
As said before, these systems are available from time to time on Ebay, esp. MVME197LE, and sometimes even for free at your local dumpster.

What I'd like to know, if that do ppl really use it, if yes, what for? it's 25Mhz, is there any possible commercial use or it's just for fun?

You could say the same thing about VAX, m68K, et al.

And it would still be relevant: is there any practical, _real_ (non-just-for-fun) use for this system?

firewall
mail server
nfs boot server
log server
etc etc etc.
I don't have those excotic platforms :( but I do use a 25 Mhz machine as bridge

I'm not absolutely sure it'll handle the load...

So wtf does 25 mHz say. Hmm, let's see. Amiga, x86, Mac... etc. etc. and you compare those all regarding the _mHz_? LMFAO only hardware noobs do that.
OTOH i don't think such a bridge would receive much load.
By Anonymous Coward () on
Just remember to put in enuf RAM for all the state tables.
And besides that, if I find an ancient 386 in the basement I will try to setup that as bridging firewall. That way I can use my 25 Mhz pc as DNS server of spamassassin box.

That said, I think most users would probably get more day to day benefits from the upcoming AMD64 (x86-64) support - which will likely entail migration to a newer version of gcc & adding propolice along with that as well. Some architectures are kept around mostly I think for developer bemusement, and there's really nothing at all wrong with that.

Reason would dictate that after the fall release of the consumer versions, more developers will be able to get their hands on gear and native porting efforts might get some more widespread support. Whether that pans out is largely up to the developers; though I'd wager that donations of appropriate hardware would help things along. :)

We need a newer gcc for that first. We cannot drop 2.95.3 entirely due to the older platforms that are really badly supported in gcc3, so there will be both versions in the tree as it looks like.
getting gcc3 into shape (propolice beeing the main point) is one of the major tasks for 3.4-current.

one can use low spec machines such as this as xterminals, NIS servers, NTP servers, backup servers (provided sufficient disk space), teminals (top, log tail, + user shell)

What are the advantages of a Model-T over a 2003 Ferrari or Rolls Royce?
An embedded processor like the later Motorola '000 chips is nothing like a Model T Ford. If we have to use the abysmal car analogies, then the Motorola 88k is more like a Ford Ka or Honda Civic. Perfect for what they are designed for (low power consumption, high reliabilty, modest price).
Yes, a Ferrari is like a 3Ghz Pentium PC - innefficient design, high power consumption, unreliable with a low mean time between failure. Might have nice case though if you into penis extensions.

modest price/low power consumption in our days - maybe, i.e. compared to state of the art CPUs with a clock frequency almost 10x as high.
in their days (around 1990) i don't think they really had a modest price or a low power consumption in any case.
really weird comparison you made.

how you come to the conclusion 88k chips are embedded processors?
Because I was generalising about the Motorola m[68]8k processors. They may have been desktop and server processors once upon a time, but Motorola have shifted far more for use in the embedded market. It's just a shame that the m88k was pulled in favour of the m68k for embedded stuff.
in their days (around 1990)
I'm pretty sure they were still shipping them in the mid-nineties for use on all-in-one boards.

Nevertheless, additional ports are always healthy for an OS.

Why does this port exist? This port exists because it can. People in the past (Nivas Madhur, Dale Rahn and Steve Murphree, Jr.) just _cared_ enough about this hardware to work on an OpenBSD port to this architecture. Of course it serves no mirific feature. It's just _hack value_.
What did this port bring to OpenBSD? Well, I can not answer for the other persons involved, but this brought me a hell lot of knowledge about gcc internals, which will be (and has been) handy to help diagnose compiler problems or devise workarounds or fixes. And an ever-improving knowledge of the kernel code.
Why are people staring at the mention of 25MHz? I honestly don't know. My main mvme88k development machine runs at 33MHz... (-:
What can be done with such a slow machine? Lots of things. Lots. Network status test. Local name server. Small file server. Mail server. Whatever. Although the speed of the average hardware has grown uncanny over the last few years, old machines can still catch up with reasonable tasks as long as they run a lightweight operating system, such as OpenBSD.
What where these machines used for? Anything. Although their VME background makes them preferred for real-time systems and robotics, they ran SysV/m88k by default, and are general-purpose Unix systems. While I got all my mvme88k boards from Germany or Netherlands, I am aware of people using such boards in Russia and USA, for instance.
How stable is that snapshot? Pretty bad, I'll confess. This first snapshot was a proof of concept, mainly to prove that all this gcc work was paying off. It has two evil killer bugs I won't mention here (because the I know the few mvme88k users around here and we have been in touch about this) which prevents this snapshot form being used for any serious work. As I write this, I just commited a workaround for one of them, and I hope to fix the remaining one soon. But this does not matter anyway - see "hack value" above...

two Dolphins. The System100 was actually running Oracle for m88k at a townhall here in Norway. Even with it's 16MB of Ram it managed to serve the entire
comunity. It was given to me after I replaced it with a Compaq server, that in fact caused woe and
despair due to the fact that it was SLOWER in handling requests than the m88k! We had Oracle come in and tune the database, and also some technicians
from Compaq to check the new server. At the time, one of my trainees took over the project and seemed
to solve the problem (faulty harware, wrong clock settings from the factory, other stuff I no longer recall). This is the only Compaq server I ever worked on, so I do not claim much knowledge about them, but I DO know, they missed the m88k after I took it with me. Another thing worth mentioning is that both my models have a default of no less than 3 inet interfaces, mainly because the data was meant to travel on a protected and secure channel
(welfare offices, social security, medical senters, government plans..). About OpenBSD, my interest in running OpenBSD on these machines is the opportunity of running a modern OS with all the benefits that includes on an anicent dinosaur..
Pretty neat if you ask me :-)
Just my 2c.. /Luke
