@metalmac

While Efika is only behcmark of how could this nettop perform,
just posted SSolies speech from Cloanto`s vimeo to You Tube

Hope it will expose the news a little bit more, and its great to hear
all those nice promises of AmigaOS 4.2 development (e.g. new printing system)

It seems Hyperion is listening what people say, and hope that with SAM460 and X1000 sales and and nettop sales next year they will have resources to speed development up: AmigaOS 4.2 is wanted as next major update!

Just mentioned the Netbook combined with the words 'Amiga' and 'somewhere 2012' and she didn't even complain. So, I hope rather soon I'll be on the OS4 track as well

i discovered the same when i got back from amiwest. apparently the netbook concept is more agreeable financially and otherwise.

now all i have to do is figure out a way to explain getting the X1000 as well....

I got a more reserved response when I mentioned it... "I see... But you've already got 3 laptops - why do you want another?"

She may have a point

I should get that too, but didn't. And my PC laptop is falling apart so will need replaced at some point. (hinge covers are missing, one of the two battery clips is gone (wonder where that spring went inside...), rubber bumpers around screen are gone, but it still works for now)

Also want either a Transformer2/Prime tablet OR Slider (if slider gets the newer CPU as well it wins) and perhaps a PowerBook. Should fix up my iBook and sell it. (dead LCD backlight)

And if we get a performance AmigaOS laptop, I'll go for that too.

@Daedalus

Now there comes the clever part of the game

The wife was talking about getting an extra laptop for one of the kids 'because he needs it at school'. Well, I'm no fool. So I said: How about getting you a brand new one so he can get yours? No wonder she replied that that was a good idea.

Now comes the clever part. She asked me if I wanted a new laptop as well, as that would be only fair. Ha... chances! There I see a finger...

I said that the boss is supplying me with a brand new luggable workstation but that I would love to have such a nice little Amiga. To my surprise, she agreed!

So... roll out that netbook, take your time guys... glue at least 800 MHz in (if impossible, I'd settle with the 400 MHz as well) and I'll get one.

I only will buy it with 800MHz

@thread

Seems on the netbook front someone got a reply from A-EON and Hyperion:

Quote:
Both A-EON and Steven Solie pointed out that AmigaOS does not need cache coherency so it will perform pretty well on the MPC5121e, a problem heavily noticed with the LimePC running GNU/Linux and during development of the MPC5121-based Efika.

Moreover they pointed out that AmigaOS is meant to run on "vintage" machines as well, with low system requirements, so even a 400Mhz processor is good enough to run AmigaOS pretty well.

Maybe something went lost in translation, but if you click on that link you'll read the exact same thing, I'm surprised too. And also, it seems Hyperion directly will distribute the thingie (I'm pretty sure with AmigaKit's help at this point).

Well, AmigaOS has already been adapted to the A1 which had BROKEN cache coherency, so obviously porting to a CPU where the behaviour is well documented should be a cake in the park

The thing about the MPC5121e and friends is that it has rather a lot of high-speed IO on a slow core. The cache inside the core therefore CANNOT hear all the things happening in the IO blocks, as this would completely KILL any performance.

The memory interface is fast, the IO blocks are fast. The core is slow.

only Amiga makes it possible: cache coherency is just "nice to have"

Oh but it is nice to have. But marking dirty when doing DMA surely isn't the end of the world. Linux supports it just fine, btw.

I watched Steven's speech from a video and he said the price being from three to four hundred dollars and not three to five. Now everybody else is quoting someones misquote everywhere. And availability was the first half of 2012.

Wasn't that also a feature of the earlier 68K Amigas? A 7MHz 68000 sharing the memory bus with 25 DMA channels, each on a 3.5MHz clock.

About cache coherency, I see many assumptions (and some of them coming out from the past), it is not clear for me yet but I recommend to interested people to read chapter 4.4 (Memory and Cache Coherency) of the e300 Reference Manual.
It is very informative about WIMG page attributes and the fact that the e300 core has 2 possible coherency modes (MEI and MESI), ... and much more.

@Tomppeli

It seems that limebook and it's derivates have been sold for about 100...220USD around the world. So I do not see it impossible that it hits in the price range of 300-400USD with AOS4 & 512M RAM.

I have to say I just read that post and I think it is all "lost in translation". I for one cannot understand what is being said in the article and I think I am the one being quoted (in part)

Anyway, I'm just pleased we will hopefully see an entry level Netbook available in the not too distant future.
