- This may be so but some sort of base config must be defined because
- if the new amiga has some form of custom chipset then anyone runnig
- the OS on say a Power Mac will be have a much slower system, because
- Intuition/Amigados/Exec will have to emulate many parts of the new
- Amiga's system using only the CPU and the Mac's Video chipset,
- limiting it and slowing things down. A possible solution to this would
- be to sell (or bundle with the OS) the new Amiga's chipset on a PCI
- card, or just a cut down version with the major features, this would
- mean that the OS could autosense and use the card to provide all of
- the amiga's benefits.

- Kickstart 37.X roms (2.0) were 512K and I think 39.X (3.0) and
- possibly 40.X are too. Also as you say having to add 4mb to the
- system conflicts with the amiga philosophy, and means that the base
- price of the system will be pushed up, meaning features will have to
- be left off to reduce it or the price rise to PC levels.

-
- Sticking the OS on a PCMCIA (simm's won't work) card is feasable but
- would be expensive to make and upgrade. A better idea would be to put
- the OS on a flash rom in the amiga, giving fast access and meaning
- that OS upgrades are possible just by renting the new OS version on a
- PCMCIA card from escom, plugging it into a slot, instantly updating
- the flash rom and then sending it back to AT, much cheaper and easier
- than the present system of plugging in new ROMS. For the OS on other
- systems, the flash ROM system could be included on a PCI card with
- AAA.

-
- Personally at the moment I think the PC is to bigger and blinkered
- market for AT to make serious inroads into, just look at your typical
- PC owner, upgrading someting every week to keep up and so blinkered by
- microsoft he wouldn't know pre-emptive multitaskingis it came up and
- hit him in the face. Also by porting the OS to the PC what about
- software compatibility, most risc processors have similar features and
- the PowerPC chip which AT are going to use is used in a variety of
- computers, so potential markets there, but the PC uses x86
- architecture and having to make the OS interperet everything to run on
- the PC will make it slow, big and ungainly (just look at WindowsNT),
- so for now just stay away from the PC.
- As far as the Mac goes, if they leave this they will be missing a huge
- market because one of the Mac's main markets is video use and this is
- also one of the amiga's strongpoints. By using the AAA chipset AT
- could provide excelent video facilities for Mac And amiga users and if
- they want to make set-tops they must use AAA because by using a
- standard chipset they elimiante the video market because all standard
- chips only output at VGA frequencies without expensive encoders (try
- connecting a pentium PC to a TV). The Acorn is an interesting
- potential market but all Acorn users seem to be severely Xenophobic
- about other computers, so breaking into it would be difficult.

- ^^^^^^^^^^^^^^^^^^^^^^^
-
- Even the OCS chipset could do things "cutting edge" chipsets can't do
- today, so why should AT disregard AAA just because it is a couple of
- years old? It offers chunky and planar modes at video frequencies to
- give fast and fringeless scrolling for video titlers a £150 video
- modulator is needed to achive half that on a PC. It offers lots of
- other advantages and seems to have an amazinv price/performance ratio.
- For example Apple are about to release a Texture Mapping Card for the
- PowerMac in the US for about $300-$400 alone! AAA offers this and much
- more for about 1/4 or less of the price. It gives features mac users
- would normally have to sell several organs to get!.

- Incedentally in article <X5kVx*sA0@mkmk.in-chemnitz.de> Floh replied
- about AAA that:

-
- Even with all the extra development needed it would still be quicker
- (and probably better) that asking an outside team to design a new
- chipset, Maybe AT should try and pinch Lew Ecchebrect (did I spell
- that right - probably not) back from scala, he's a brilliant hardware
- engineer and would probably have AAA running in a week.

-
- MagicWB does go a long way to improving the look of WB, but my prize
- for best WB enhancer goes to................ MUI, it's a brilliant
- piece of coding (if a bit slow, but MUI v3 is meant to fix this, does
- it, please tell me!), allowing virtually every intuition function to
- be altered to your taste. Maybe AT should build in (and update!) this in
- the new OS. How about hiring Stefan Scwartz ( He did program it,
- right?) to build it into intuition for them.
-
- Now, a correction, near the end of my posting I said:

-
- Floh corrected me on this, it appears that PCI cards do use a ROM chip
- id, it's just that the PC dosen't use it. Does this mean that the Mac
- does?
-
- Finally, in the replys posted so far my idea of a Devlopers Pack seems
- to have some support, maybe we should petition AT, what do you think?
- Maybe AT have already read this, do they monitor these usenet groups?
- If so MESSAGE TO AT:
