The video shows AOS4’s speed, stability, and responsiveness on a PPC G3 800HMz.About The Author Eugenia LoliEx-programmer, ex-editor in chief at OSNews.com, now a visual artist/filmmaker.Follow me on Twitter @EugeniaLoli 23 Comments 2005-03-21 9:42 pm will there ever be a chance to see amiga 4 go multiplatform? 2005-03-21 10:02 pm that is what I will have when this OS gets released…ever…I migh even be in the grave :p just release the darned thing 2005-03-21 10:08 pm The GUI looks fast and responsive but I can’t see how one can see stability in such a short video? As both warm and cold booting where shown I would rather think it is unstable, why else would he need to “brag” about it? And for those that think I would buy a AmigaOne just for downloading and enjoying this video think again, the system is to expensive, too slow (for me), too unreliable (no memory protection) and too unsupported (hardware drivers and software). 2005-03-21 10:22 pm I’m really looking forward to this update – i’ve already got a XE 800mhz waiting.Yes, the hardware is expensive, but the machine & os4 is just so much fun! a new world compared to the boring wintel-boxes i use at work.once os4 gets released im planning to order a microA1 aswell 2005-03-21 10:24 pm it’s not all that. there is great amount of advantage to not have memory protection. The speed gain by droping that feature is quite significant. In fact i think that as compiler get better at detecting obvious crash code and that VM machine can be use to run in isolation app for a testing period, memory protection might eventually go awway in it’s current form. 2005-03-21 10:57 pm Some parts of the OS are already memory protected but full memory protection is planned for future releases, this due to incompatibility with most OS3.x software (OS3.x can run with MMU-less 68k CPUs).There’s however the Grim Reaper included with AmigaOS4, which is a software crash analyze/catcher with the ability to kill the offending application or attach to a gdb debugger.Old screenshots:http://amigaworld.net/modules/features/index.php?op=r&cat_id=6&rev_… 2005-03-21 11:11 pm @ Tudy> will there ever be a chance to see amiga 4 go multiplatform?AmigaOS4.0 is currently only planned for PPC based solutions. Mainly various PPC-board expanded classic Amiga models and the new AmigaOne systems.Large parts of AmigaOS have however been rewritten to allow better portability and there’s a HAL, however there is currently no public information available which suggests that AmigaOS4.x will support other CPU architectures in the near future. However for the distant future AmigaOS5.x is supposed to become ‘multi-platform’. 2005-03-21 11:13 pm BTW, that video mainly focusses on demonstrating some components which will soon be released and have gone through extensive beta-testing. Some of these components shown include:– WarpOS emu wrapper: This allows you to run older PPC Amiga software seamlessly with AmigaOS4.Example: Screenshots of WarpOS version of Wipeout2097 on OS4http://www.soft3dev.net/aos4-warpos.php– Petunia JIT: This is a faster seamlessly usable 68k Amiga software emulator than the one which is currently available to ordinary OS4 Developer Pre-release users.– Warp3D 5.0 – 3D driver system / a low-level API for programmers to access 3D hardware on Amigas. MESA (OpenGL API) can sit on top of Warp3D.Although it’s great to be able to use your old 68k and PPC Amiga software seamlessly with AmigaOS4, IMO (much) faster OS4 native software does the OS more justice for public demonstrations, at least when showing the OS to people without any Amiga background experience.All the BeOS/QNX/Zeta/etc users I know who have seen AmigaOS4 multimedia performance using natively written software have been thoroughly impressed:http://uniweb.free.fr/os4/moovidamp.avi (older video) 2005-03-21 11:29 pm Please tell me my Mac can run this when it’s released.. it’s a (big fat 64 bit) PPC after all 🙂I’d love to try this at home! 2005-03-21 11:49 pm No, im afraid that your mac will not be able to run os4.fuskoSCN 2005-03-21 11:51 pm No, the Mac is currently not supported. Macintosh computers come with unsupported hardware and there are currently no plans to support such hardware in the near future.IMO the AmigaOne currently cannot compete head-to-head with the Macintosh specifications and production costs (economies of scale). So IMO support for the Macintosh platform would likely almost kill the AmigaOne market completely (Although the Mini-ITX form factor is cool) and thus would make AmigaOS4 development entirely dependent on Apple’s actions (such as willingness to share hardware documentation).For example Be Inc ported BeOS to Mac hardware after moving away from their custom BeBox solution. However Apple made it difficult for Be Inc to propertly support newer Mac hardware (and eventually moved to the x86 where Microsoft alledgely made it difficult for Be Inc to partner with various high profile PC makers).IMO the AmigaOS4 team should not repeat such past mistakes. 2005-03-22 12:21 am the pegasos platform my also be a nice home for OS4 2005-03-22 1:18 am “the pegasos platform my also be a nice home for OS4”I agree with that.I will most certainly buy an Amiga in the future, even if its future looks cloudy and dark.It´s just a simple sollution to the Micro$oft problem I suffer every day. 2005-03-22 1:22 am @ Megol“I would rather think it is unstable, why else would he need to “brag” about it? ”Well it´s in Beta-stage. I would be amazed if it wasn´t.. 2005-03-22 2:12 am 800Mhz and old hardware, a must for people with money to waste.Better off to pick up a board in a years time when they have off loaded the over the top prices to those 100% loyal to the amiga memory. 😉Awesome machine 20 odd years ago, but as much as the die hards insist, I am afraid not enough will support it now at those prices.Raincheck in a years time, and we shall see who is right.Good luck anyway 2005-03-22 3:08 am there is great amount of advantage to not have memory protection. The speed gain by droping that feature is quite significant.I can assure you that the disadvantages of no memory protection far outweigh any speed advantage. Having to reboot one’s computer because one careless programmer routinely takes down the entire system puts quite a dent into overall system performance. 🙂 It is intolerable on any computer with a “modern” OS. One could crash the Amiga by omitting the ampersand in a scanf (and I often did, back when I was learning Amiga C, which reveals defects in C first, the Amiga next, and myself as well).Later versions of the OS added some sort of minimal memory protection, so that one could choose between suspending some programs and crashing the machine. The number of programs that fell outside this umbrella of protections was nevertheless unacceptably high. 2005-03-22 4:52 am i agree, but i still would like OS to allow not enabling them (on the fly btw). A cad station or a server have no need for protection if they run always just one bug free app.Hey Mike, do you know if they are going to sell an actual amiga? I’m sure some would pay the extra mile to get a branded A5000.Personally, i see no advantage other than curiosity to buy such a ppc board+OS. If they would allow you to expand it with with custon chip on PCI card (customised to go faster than standard PCI) it might be worth it. Why not have supper copper blitter on those card.IMHO it’s the only real advantage for an OS maker that also sell hardware, to put hardware feature not found elsewere, playing catchup don’t cut it for me. 2005-03-22 1:14 pm @ AlienSoldier> i agree, but i still would like OS to allow not enabling> them (on the fly btw).AFAIK, MP once introduced will remain optional mainly for legacy software compatibility reasons.However IMO AmigaOS’s speed is mainly due to its good and flexible pre-emptive multitasking microkernel based design combined with an efficient memory footprint/usage approach. For instance AmigaOS was always a lot faster than 68k MacOS (no MP) when running on equivalently powered hardware.> Hey Mike, do you know if they are going to sell an actual amiga?The AmigaOne systems are licenced to carry the Amiga brand and of course the classics running OS4 are also Amiga branded.For instance dealers can assemble (from standard off the shelf PC parts) and create complete systems based on (Mirco)AmigaOne motherboards and stick an Amiga logo on the box. Most dealers already provide complete systems, next to just the motherboards. 2005-03-22 4:36 pm there is great amount of advantage to not have memory protection. The speed gain by droping that feature is quite significant.Either “quite significant” to you means the same as “very small”, or you haven’t heard of translation look-aside buffers (TLBs). 2005-03-22 6:55 pm There is no such thing as a bug-free app that possesses anything resembling usefulness. Even if a machine were dedicated to running only one app, memory protection would be useful, insofar as a badly-behaved thread wouldn’t take down the machine & cause data loss. Especially where (say) CAD is concerned. 2005-03-23 12:33 am WELL, windows has memory protection, isn´t it? and it crashes, in fact more times than the the non memory protction amigaos.So memory protection is not as usefull as you claim, crashes anyway and makes the thing slower 2005-03-23 3:36 am I’m with you. Windows include memory protection, but we still got Blue screens, and sometimes even complete freezes without a message. And do not talk about Internet Explorer. When something brings it down, usually make the whole computer unusable. 2005-03-26 1:34 am WELL, windows has memory protection, isn´t it? and it crashes, in fact more times than the the non memory protction amigaos.The fact that Windows can do something badly, doesn’t mean that it isn’t worth doing correctly. Unix and VMS do memory protection quite well, and don’t slow things down much (if at all).
