Belive me Spectre660 have more experience than you with linux PPC and PowerPc ...

@Everblue

they might not have an "intention" but if they ocassionally do a 50 units run and the other board will be 10 times more in one run as apparently announced, what will effectively be the outcome? any thoughts? ;)

I have asked ACube on their Facebook page about the Sam460CR and they told me they have no intention of stopping its production.

Are we sure ACube are involved with A1222?

In this case you need that the kernel supports the 64-bit wide registers of the e500v2, which requires some work.

This also slows down the task switching and the interrupts handling (at least), in general (so not only for the "SPE application").

Only slowdowns, but they can run without any other problem, since the FPU (and "string" instructions) emulation is totally transparent to the existing software.

Welcome!

right (post #466 here):

Emulation of FPU instructions will be handled transparently without significant impact on performance. So no need to either recompile the OS (the kernel is obviously always specific for a certain CPU) or any applications.

you dont even need to speak it out yourself. people will read from your lips, whatever they wish for, and fill in the blanks as facts. and then all is fine again (post #468):

Speculation on my part .

Oh, I appreciate your candor.
In some cases it would be preferable.
And using the non-standard fpu incorporated into the e500v2 ought to be a better solution for software that needs an fpu than emulating the standard unit.

At this point, I'm reserving further judgement.
A-eon invested the funds and the time creating this board, its going to happen.
So, if its price is right and its performance is a least on par with the Samantha, then it was a good investment.

And nothing precludes A-eon from further introductions.
After all, the e5500 core I would appear to be so fond of is a dead end.
So while I would have preferred a T10XX solution, neither that core or the e500 will be developed further.
Only the e6500 core is shown in current roadmaps of future introductions.

We have the X5000, and hopefully one day we may even see an e6500 cored cpu in its successor.

In any case, PPCs ought to be viable for at least 5-10 years, and I'm extremely fond of this ISA...so, OK.

@Zylesea

'No need to' is not the same as 'cannot benefit from'.

There is no need to compile altivec binaries for example.

According to HyperionMP your speculation is wrong

The "no problem os4 already woks on the board" did not come from Hyperion Management or AmigaOS developers .

It may have been assumed by those saying this because AmigaOS developers have had boards for several months.

@wawa

So, if/ when this is sorted out and its on par with Sam 460 at 500 £. This is going to be a bargain in OS4 terms ?

@eder

in software you can also test parts of it, f.e. you can define test cases that run against routines to see if there are problems. As I understand it not yet integrated in AmigaOS because AmigaOS is still not running on the hardware.

How can something be slow, yet not tested

Just wanted to give you guys my opinion. BTW I have been a loyal Amiga follower for many many years buying my first machine way way back in the 80's programmed in C, Assembler and for a time I pushed my Miggy to the extreme with the likes of Lightwave & Imagine etc. I have followed the community here for many years and also at amiga.org as well as aros-exec. I don't have an Amiga right now, not including UAE, and that's simply because because the hardware is so expensive.

Lots of people complain about the cost of Amiga hardware and I would love to be able to afford a brand new "NG" motherboard (I say NG but isn't the reality that PPC hardware for Amiga is "current generation") and the reality is it is out of most peoples reach. This hardware is perfect for me and I have no doubt many others. It gives me a base platform to work from at a respectable cost and gives me an entry point onto a system that I really want to use. Am I concerned about MIPS, MOPS and GHz - no as long as the system can run the software better than an upgraded A4000 which it could.

I don't expect lots of bang for very little bucks. An entry level machine just to bring me back into the fold and I have no doubt it will bring other users back to Amiga too. Would that not make business sense. Would that not bring other ex Amigans back to the scene. It's hypothetical right now - but this board would get my money from my pocket and back into supporting Trevor and future Amiga projects.

I run my own business - if I had an entry level machine to evaluate then Amiga could reach and support my business also and what I mean by that is potential sales increase from a simple underpowered board to sales of 5 or 6 X5000's.

Only Beta-Testers will be able to buy the Tabor until AmigaOS 4.x is working to an acceptable standard. Just like the X5000 not being available until that standard is reached.

Assuming people buy Tabor and there is only the slow FPU emulation and the fast one needs a long time or is not possible at all whyever (not uncommon in complex software) or is not compatible enough customers will be very disappointed and another round of Hyperion bashing. I like Cyborgs style, honest explanations. The others should take over that style too. Just my 2 cents.
