This is good news, but I wont hold my breath

I too would like an answer to the A1200 question. looking at the photo I think it's safe to say it wont fit in the desktop wedge, but a version for towerised 1200's would be excellent.

Gotta be the grumpy old guy here and say: why PPC? Why an 040??
Not really interested in this development specially since it is for A3000 and A4000, but good luck to Gideon, massive respect to him for 1541U (please get back on that).

Akira, Given the rarity (and cost) of the now rare BPPC and CSPPC's I think it's a pretty obvious choice. It also means more of us can run OS4 from our favourite platforms

Although aiming for the less common model baffles me a little :P

Got to say Kudos on this, I really look forward to reading more about this! It would be awesome if this gives OS4.1 Classic Users the speed needed to get the most out of this OS and dual booting with OS3.x would give an awesome setup

I'd definately pre-order one and would be happy to pay a desposit now if it helped with developement.

I can also offer my services for testing, being an experienced OS4.1 Classic user with multiple A4000 setups (A4000D RevB/A4000D RevD+Mediator4000D and an AT A4000T) I could test accross multiple platforms

Keep us posted!

Steve.

i think ppc would of been the next logical step for the amiga,even if im a 68k kind of person.



on a positive note the 040@33mhz is connected to 128mb of ddr2 memory

has anyone seen os 4.1 on a cpu over 800mhz,this thing will fly

My Micro AmigaOne is 800mhz and it runs OS4.1 very well as seen in my Youtube Vids (search Fitzsteve on Youtube)

And I'm sure it runs ultra smooth on 1ghz+

040 33mhz is a nice enviroment to run OS3.9 with RTG/Sound Card/USB

My A4000D is 040 @40mhz + 128mb DKB3128 + CV64/3D + Toccata and is an awesome setup to use OS3.9 with and one of my favourite Amiga's

Nice effort!

I have some questions:
-The PPC you have chosen uses incompatible FPU. Any plans to change it?
-Will you put 060 as an option? My big box miggies use 060 and my demos require 060.
-If PPC part works correctly and has access to Amiga motherboard why not remove entirely the 040 and use a JIT emulator? That way it would be faster than 060 and design would be easier.

I can't wait until this is released and I plan on getting one, even if I have to sell both my kidneys.

Having said that, though, and after seeing the picture of the board on their website, I have some design concerns related to using this in a stock 3000D, like mine.

Personally, the CPU(s) in it don't bother me. Either an 040 or 060 are going to be huge horsepower upgrades for my machine. (Side note: to use this, do I need to make any mods to the 3000D? I read somewhere about having to make mods to the board for CPU cards to work, or maybe it was CPU cards with SCSI?)

However, here's my concerns:

With the SATA connectors, there shouldn't be an issue because they make right-angle connectors, but I think the DVI connector would be blocked in a 3000D. Furthermore, unless the built-in video also includes a passthrough for native Amiga video, I'd probably opt to stick with my Cybervision 64.

On the site they do mention that the ethernet jack on the card would likely be blocked in a 3000D and have included a pin-header for a breakout cable, however, at the cost of speed. (100mb is still a step-up from the 10mb on my X-Surf, but the full 1Gb would be awesome.) I think they'll need to do something like that for the USB connectors as well.

i would like a new ppc model for the 1200 please with a nice 040 ,and lots of memory

why make 1 for a 3000/4000 without thinking about us poor lonely 1200 users which theres more of.

+1 on the A1200 version, that would be excellent.

(Tried sending this to contact at ultimateppc.nl, but it bounced for the last 3 days)

Hi there! This is Jason McMullan, one of the lead m68k developers for AROS.

I was wondering if you would like AROS support for your RTG, USB, Ethernet, and SATA devices?

Also, is there m68k visible ROM space on the device? If so, I should be able to make ROMable versions of the RTG and SATA device drivers, suitable for both AROS and AmigaOS m68k

I have an A4000 suitable for device testing, if you do not have the time to test code changes sent to you.

The JIT emulators I have used in the past usually take a ~40x performance hit - so on a 1Ghz 'host', you end up with a about 30Mhz-25Mhz of emulated speed.

Often, you will get 'apparently higher' speeds (ie Rosetta on the Mac OSX platform), because the JIT is only recompiling the application - all drawing, disk, os, and input calls are handled by the host OS.

That would not be the case for the system you discuss - it would be emulating the entire system, not just the applications, so the 40x speed hit effects everything.

Find me a m68k JIT for PPC hosts with better performance numbers, and you would then be able to make a good case.

That's really bad performance.

Apple software is overrated.

No problem, that 40x speed hit doesn't affect good JITs.

Trance. Feel free to send me any m68k bruteforce test and I'll execute it.

Example of Lame m68k running on trance powerup (old version) on 603e/200Mhz with no L2 cache and slow edo ram running twice faster than a 68040/40Mhz:
http://www.ppa.pl/forum/amigaos-4.x/...anego-68k-test

Example of Ocean Machine from The Black Lotus running on AGA+JIT on a 603e/240Mhz (no rtg, no ahi, just the ppc writting to custom chip registers and chipram using slow ram)
[ Show youtube player ]

A peg1 running at 600Mhz runs rings around 060s running m68060 code.

And despiting Petunia is slower than Trance it's still faster than 060.

Ppc should be quite good at emulating 68k. We have done such tests. Afair you could compare 604 to 060 clock by clock in running 68k code. What costs much in say uae is custom chip emu. That said im against yet another Hardware tailored version of aros. Its up to the Hardware devs to provide compatibility to existing branch, be it 68k or ppc, Imho. Otherwise wie will get lost in translations..

Really?
So I would like "SN00000004"

I've sent a msg to GideonZ to offer my PPC CPU (IBM).

I guess my views come from just not giving a single toss about OS4 or Power PC in an Amiga.

What I would wish someone would do is an affordable 060 so I can watch those demos...

I think I wasn't clear enough. I am offering help to write m68k drivers for the SATA/Ethernet/USB components, that can work on either AOS 3.x or AROS m68k.

I do not have any time nor intention to support a e500v2 PPC CPU, since that is incompatible will all Amiga PPC OSes. (Due to the crazy SPE FPU unit)
