Now that was fast

This is not completely uninteresting. Cool that MorphOS runs on it already. Increadible job by Frank as always.

Anyone knows if the T2081 variant will be actually be realized? And the price of it? I might actually be a little interested in that.

Anyway, it's cool to see how this board has progressed. And that there is no pre-sale going on with coupons or empty promises or such. This is exactly how things *should be done*; the devs creates a product and when it's ready it's being put on the market.

Look at that never ending story about that laptop motherboard. The entire idea with that seems to be raising money without making any products. The only things delivered are new excuses and new fund raising goals. Like so many things in the Amiga history. And the Tabor is the biggest joke.

But these guys just develops and delivers. Well, not to end-users yet, but at least the thing seems to work and MorphOS is up and running! Only remaining issue is the economy thing...

It should just be cases of soldering a T2081 to the board instead of the T1042. No idea about the board in general, the T2081NSN8TTB is the least expensive 1.8Ghz part at just over $200, so it should be about a $100 difference between the two variants.

Yes I understand that the possibility exists, at least in theory. But it seems that none of the prototypes has this CPU yet though, so it still hasn’t been tested in practice? And maybe I’m marked by passed experiences but haven’t we read so many times about specs of upcoming projects where it says “up to” this and that performance, clock speed etc, only to fall short in the end, only offering a less exciting option for economical reasons or whatever?

But the point is that all PPC options that still exists are rather weak by todays standards, as we notice in CPU intensive applications like web browsing, so there is absolutely no reason to choose anything less than the most powerful option. We will need the highest possible clockspeed, we will need Altivec. So in this case, anything less than the 1.8GHz T2081 would be uninteresting IMHO…

I not sure about every detail, but from what I have gathered the made just 5 (or only a few more) boards in one run and they all have the smallest SoC option (I'd guess it's the only one that could be bought at non insane prices in such low volumes),

So the question is what will they do the next run which kinda needs to be done "soon"?
Just make enough to fill in the minimum order for one the 2 bigger SoC?
Give all them that small SoC again?

Sales will be an issue as these board would appear well before any public MorphOS (let alone OS4) release, but economics of scale is needed anyways. And someone has to somehow finance the production run.

So, sales "only" to people like myself who could expect a beta ISO within a reasonable timeframe and the die hards not bothered with year(s) long wait time.

Today probably no one knows it for sure. Maybe authors, maybe not You have to wait a little - knowing how to wait pays off in our world.

Developers selected T1042 like main CPU for Mirari, so it is expectable that developement is done with this CPU. It's reasonable to expect other versions when the T1042 works...

I agree with you in this point.
Fortunatelly for us, this is quotation from NXP pages:
Code:
So, chance is big. And even if the author didn't make the T2081 version, we can replace the CPU ourselves.

Of course, that's too high a level for me. The most I can do is soldering of on/off switch . But there's a perfect little company here in Prague that can do that kind of thing for a very little price.
More complicated can be change of frequency.

But comments about CPU swap was moreless a joke, simply let's wait for developers. I believe that a powerful version will be.

Actually, the smallest pin-compatible one would have been the dual-core T1022.

Also firmware changes are probably necessary.

I can't help to think it's cool that they are using MorphOS for testing this.

Wonder if there is any room to overclock the T2081 beyond 1.8GHz? Probably not a lot though, since 1.8GHz is quite high already to begin with...

Maybe someone could run a Browser Benchmark on that machine to test how fast this Mirari is compared to the G4 and G5. And some other Benchmarks as well.

Quote:

I'm afraid there's only one Mirari board running MorphOS ATM. And probably Frank is too busy working on the port to do heavy benchmarking on this machine.

Nevertheless - he did a quick dhrystone benchmark and Mirari (at 1,6 GHz) scored 2436 DMIPS (vs 2056 for a 1,67 GHz PowerBook G4). For comparison - G5 is above 3000 (even about 3500 DMIPS for a 2,5 GHz version). I guess the results for a 1,8 GHz (or slightly overclocked - maybe to 2,0 GHz?) T2081 model can be really close to G5 level performance at fraction of its power consumption level.

certainly the graphic card could be better on this computer

Quote:

In some cases Mirari with T2081 can be even faster than Powermac G5 Quad - in dual-threaded mode on all four cores, for tasks without AltiVec

In any case, Mirari project is very promising.

We're still talking about running MorphOS, aren't we? ;-)
As far as I understand, the 3500 DMIPS figure is for one single G5 core.

> for tasks without AltiVec ;-)

Why? T2081's e6500 core does have AltiVec.

@Andreas_Wolf
>We're still talking about running MorphOS, aren't we?

Yes, MorphOS. I believe that MorphOS 4.0 will have MP support

>> for tasks without AltiVec
>Why? T2081's e6500 core does have AltiVec.

e6500 core has some resources ( units ) doubled - for two threads. But AltiVec is only one per core, so AltiVec computations are not faster with two threads.

Yes, indeed. Thanks for clarification.

A second batch of 10 boards (or more) is planned after they have evaluated the functionality of the first batch. Hopefully they will make some of these with the T2081 CPU. Also, price is not yet decided.

https://www.amiga-news.de/de/news/comments/329419.html

I hope they will sell a Morph version of the board, meaning no ”brand taxes” for useless Amiga trade marks, and no mandatory price addition for OS4 that MorphOS users won’t be needing anyway…

This has accurately been described from the start as a "community project". You will -not- find any posting from any of the 4 team members indicating even the slightest desire for "Amiga" branding.

You worry too much (evil grin)

Well one can desire or not desire a lot of things, might no 100% overlap with reality.

Sure hiding parts of the OS4 costs inside that HW price tag is a d### move, but that wouldn't be a 1st in any way.

So as long as the pricing isn't firmly announced I stay calm and cautious.

@takemehomegrandma:
as a reminder, a quote from the Mirari project website:
Quote:
At least the pursuit of a good price is there. What reality will allow, we shall see.
Anyway, I'm interested in Mirari even if it only runs Linux. And with MorphOS it will be absolutely great.
