@Derringer

Under os4 there is a jit 68k compiler
No such thing in EUAE; that's why it's slow.

This report reminds me about some the reasons I bought the AmigaOne in the first place five years ago! I see this is first message, so welcome!

Thanks for the replies, i hope the review was helpful

@fishy_fis: The custom chips "accesible" under os4. You have all the AGA screen modes, you can use paula to produce sound, etc. Even you have chip ram. (Of course hard coded games mostly use this memory.) 68k cpu switched off, but you have a 68020 emulated cpu at once.
Theoretically you can run all of the old games, apps. Of course most of them do something nasty trick, so most of them activate the grim reaper. There will be a lot of game, apps which is run ok at os4. I use a samsung 19" lcd tv, so if i want to use a game wich uses aga, i need only press one button at my remote controller to do this.
I will check my old game collection in the near future. Remember os4 classic is out only a few weeks, so i think the solutions of running some old games will increase in the near future. On os3.9 some games need only a little setting, cache deactivating or else to run. If you read whdload comments, you can see this.

@Cobra: Yeah i know it is hard task to play smooth dvd on classic. Maybe under 256Mb, or combined with a tuner card . (most of them includes a hw dedoder for this)
Or separetly the sound decoded by mp3@64 and the movie by regular way. Or a gfx card to do this. The recent pci-ex card can offload blue-ray decoding from the cpu, and earlier modells do this with dvd. Don't know if the Voodoo have this feature.

@Hammer: Ok, You don't need 8800GT for Aero. But wait the arrival of sp1..
And under "power station" I don't argue about the watts they need. I wantet to tell that you need a very good and up to date hardware to run at acceptable speed. Compared to xp, under the same hw vista is slow, while xp is flying.

@hatschi

I am too waiting for blizzard SCSI support before purchasing it !

not a big deal anyway because I have my A1XE, it would just be so nice to have the same system on my A1 and on my A1200PPC !

@ Derringer : good and well written review, thx !

@Derringer

I have read the review and I think where nice, I hope the classic will get more drivers, so the systems become more useful, for every one.

hemm... that reminds me about elbox.

Vista SP1 beta doesn't need Geforce 8800GT.

@Hammer

I think he meant that Vista is horribly slow
..and I completely agree with him!

@Richi
It's God damn slow because it is for "no brain" users. They can't work on hi speeds!

@Derringer
Nice points of view. In most of it you are surely right and I agree with you. The problem is the hardware and not the software itself. On my mA1 the OS4 is the fastest OS I ever used. I really miss the

* OpenGL implementation and better use of the graphics card capabilities
* WarpOS support for HereticII and a few great Madwizards demos

HW decoder is the only way DVDs could be played at full speed/full resolution. For example AFAIK even the Radeon 7000 on the uA1 supports IDCT/motion vector decoding which is about 80% of the entire MPEG decoding process.

(In the same time my pc can download with 450-500 kbyte/sec.)

I usually (depending on source of course) have a "cruise speed" of about 10MB/s when downloading. Just wanted to let you know!

Thanks for a good report of your experiences!

@COBRA

Is the hardware decoding of the Radeon 7000 supported on OS4?

@COBRA

I searched after some voodoo related faq, now find this:

http://www.3dfxzone.it/dir/3dfx/voodoo3/faq/2k3k.htm#q7

Don't now how far the os4 can use voodoo features. But if its full, it can be offload cpu greatly.

And i remember there were great fight between the gfx card manufacturers to which one is the best dvd playback card in the late '90 and the begiining of the 2000 years

@Derringer

Thanks for your review.

I have some question as I have some strange effects here with OS4.

Did you use the Elbox drivers for Voodoo / LAN and the Mediator or did you use the OS4 drivers ?
I was a bit confused because when I tried to use the Realtec 8029 PCI LAN device it is not stable with the buggy OS4 driver.

You wrote about "a voodoo corruption in Os4".
Yes there is one or more problems.

I tested the Voodoo 3000,4500 and 5500 PCI with the mediator in my A4000T.
The Voodoo 3000 runs good (screen modes generated with tooltypes in the monitor icon)
The Voodoo 4500 and 5500 run with very bad image quality. Screen modes generated with tooltypes through the monitor icon result in poor image quality and flickering.
It is possible to solve that problem with a more complex Picasso96 configuration using tooltype "Settingsfile=sys:/devs....your P96 settingfile" .

I personaly have some other problems with my config and I think it has to do with the Voodoo/Mediator too.

As the Realtec PCI did not run with the OS4 driver & Mediator I decided to buy a X-Surf cc3 Zorro LAN card.

The card works perfekt with my config and a Cybervision PPC.
If I use /boot OS4 with Voodoo card the system has some realy strange behaviors.

It works in the very first Zorroslot (the one near the Videoslot).
Using the second Zorroslot OS4 comes up with the WB, but doing some clicks will freeze the system (X-Surf LAN driver is not installed yet).
Using the fourth Zorroslot with the X-Surf OS4 will boot but there ist only a black (Voodoo) screen.

I did these tests at 1600x1200 and 1920x1200 resolution, decreasing the Voodo resolution will result in some more stability and no black screen (Zorroslot 4).

If I use the Cybervison I have no problems, but the cybervison is realy slow at 1600x1200.

I have an A4000T CSPPC, 128MB , Medator + Voodoo + X-surf
I tested three diverent Voodoos (3000,4500,5500) I tried different mediator setting for "Winsize" and "Swap Config" and also tried a new install of OS4.

Is there an adressing problem (crashes/black screens) with Voodoo cards especialy at high resolutions (more RAM needed) with OS4 when other hardware/resources are used ?

@Richi

AFAIK there is no driver for OS4, which would utilize the hardware video decoding capability of Radeon cards.

@Derringer

Neither is there a driver to utilize the hw decoding of Voodoo cards.

@COBRA

It would be nice to know if there are plans to create something like "p96video.library" to accelerate video

And to operate these files with a HD with the built in ide? Some centuries ago it has been the most effective tool of the Spanish inquisition. To copy files about 0,8-1MB/sec is a real suicide nowadays.

Actually A1200 onboard IDE isn't slow at all - many PC's built around the same time have way lower data transfer speeds. Basically it's just that newer IDE interfaces have become gradually a LOT better since then, pretty normal phenomena in IT world.

@hacky


I use the os4 drivers, AFAIK mediator 68k drivers a lot slower on os4.
As i read, soon there will be a patch for os4 classic. It will fix the voodoo corruption and the buggy 8029 driver.

@jupp3

As i mentioned above, when amiga's got a built in ide driver it was a miracle machine. (Booting wb, loading games from hdd etc.) But the os3.x is on 4-6 Disk (4MB), ambermoon for example was on 9-10 disk as i remember. (6-7MB) So this apps,games etc cost under 10MB disk space. If you copying things 1MB/s this is enough and fast after the floppy speed of 15-20 KB/sec. And at that time the harddisk can't produce really more speed. Now they can, just the ide interface don't. Anyway i have scsi on my amiga it operates at above 4,5MB/sec. It's not fast but enough. Just 5-6x faster than the built in ide and i use the same machine.
