- Yep.. A very long message allright :)

-
- Great.. you replyed.. It took a bit long, but better late then never.
-
- >> I never heard of the HP-PA chip, what kind of chip is it ?

-
- Hmm.. yes. But more expensive I believe ?? Could somenone give me a kind of
- list with all the populair CPU's compared to each others in performance and
- price ??
-
- >> What computer uses them ??
- FB> Multimedia/Graphics Workstations.
-
- SGI's ?? Those are fast, yes !!
-

- FB> Multimedia/Graphics Workstations v2.0 ;)
-
- I still think the PPC is more widely used and still the best choice for AT.
- But then again we will probably never now...
-
- >> I never even heard of it !!
- FB> You missed something very interesting ;)
-
- I know :/
-

-
- Yes, Parallel processing will be the future, but this can be done also with a
- RISC chip like the PPC right ??
-

- FB> The future of PPC is much less sure than the one of i.e. 80x86 :(
- FB> Anyway, IMO PPC has been the best choice (due to the commericial

- FB> commercially optimal) but much more powerful HP-PA.
-
- Yep, I agree here...
-

- FB> Hmm.. I really think that 040 has been sold, and that people asks for

- FB> problems to satisfy the request of 060's.
-
- That's right, they didn't expect it.. They probably forgot about the Amiga :)
-

- FB> Before PPC does it, practically all the others will have reached it,
- FB> including 80x86. It has nothing to do with PPC design, it has to do with
- FB> technology.
-
- Yes, but for now the Sextium (I think this name is much cooler the
- Pentium Pro) is only sold in mainframes and to the big public. Before it will
- be available to the big audiance the PPC will probably have catched up.
-
- >> I think the PowerPc chip is simply more supported.
- FB> Agreed. But we need also more power, adding the the PPC what it can't
- FB> do proporly (read: quickly).
- FB> Also 80686 will have a "MultiMedia core", in-chip.
-
- Will have ?? Isn't it released already ?
-
- FB> As always, IBM will give us tomorrow the technology that nearly
- FB> everyone had yesterday..
-
- IBM ? It is a Motorola chip in a alliance with IBM and Apple if I'm correct.
-
- >> , but then again the Pentiums are badly designed.
- FB> bigtime, but they have lotsa Mhz..
-
- Yep.. that's what counts really.
-
- >> The things about Custom-gfx-chips :

- FB> because it's crap for anything else than a static WorkBench. I haven't
- FB> seen cool games with 8088+SVGA, but I've seen them with 68000+OCS. so,
- FB> would you prefer 80586+SVGA games, or the same CPU's MIPS+AAAA?
-
- Hmm... I think you're right here. But I would rather have a BIG CPU and a
- AAAA chipset. Who wouldn't :)
-
- >> I mean they are cheap and updated very often !!!
- FB> Watch the AgaEXTENDER: it's fully programmable and thus can *not*
- FB> become obsolete, neither in 20 years. If they make AGA as *static
- FB> design*, as soon as "bandwidth technology" :D evolves, you can
- FB> "overclock" AGA of any number of times (having re-made them using the
- FB> new technology, *but* with no need to redesign them because you used a
- FB> *static design*). Quite perfect: compatible, cheap, upgradable, fully
- FB> programmable ( so you dont need to make a new chipset when i.e. new
- FB> video modes are required ).
-
- I've read the AGAextender textfile, and I must say : I was impressed !!
- I would like it to see it implemented in the new and existing Amiga range.
- Allthough the sound stuff, wasn't good enough for me... 8 16bit channels
- was the max if I understand it all correctly (which is very difficult for
- me being very a-techinical ;) ).
-

- FB> Nope. Just 1 chip and some designers.
- FB> They're re-designing AGA to make it consume less, and this is the good
- FB> occasion to change its design into *static*, allowing cheap evolution
- FB> following the philosophy above explained. It means no comprimizes: only
- FB> huge advantages.
-
- I really like the 3D sprites and the fog ideas !! Although do you how much
- the AGAextender would cost ?
-
- >> And we all know
- >> that is not the situation right now. I mean a SVGA chip costs 10$ ? What
- >> do think the Custom chips will cost if AT desgined them ??
- FB> Extremely less in the performances/price ratio.
-
- With the AGAExtender project yes, if from scratch no way..
-
- >> More then 10$,
- >> thats for sure.
- FB> Well, it's a paradox:
- FB> The "10$ SVGA chips" are cheap, but they can only run a static
- FB> WorkBench screen on low-end Amigas. So you need an high-end Amiga, where
- FB> you can spend also 20$..
-
- Hmm... yep, that is true.. But if you must buy an very expensive graphix-chip
- you don't have any money for an CPU.
-
- >> And those chips would need to be upgraded every year to keep up with the

- FB> Nope:
- FB> The design of AgaEXTENDER is fully programmable; meaning that *NO*
- FB> updates will be necessary. As soon as technology evolves, you've only to
- FB> make the same old chips using it, exploiting the new clock speeds, and
- FB> you're done.
-
- FB> If i.e. a day developers will need hybrid chunky+planar modes, both AGA
- FB> and expecially SVGA will be obsolete in a moment, as AGA became because
- FB> of chunky.
-
- FB> AGA+AgaEXTENDER will still be there doing the job with 100% efficiency,
- FB> being fully programmable.
-
- I still don't completely get it... It is very difficult just to Imagine that
- the old/slow AGA chipset can be the most awesome Custom-chipset on the market
- for the next decade at least by simply inserting an extension into you're
- Amiga.

- >> I don't know what this project means, so won't say anything about it.
- FB> You're cool pal :)))

-

-
- >> Only this..
- FB> NO!!!! ;)

- FB> The AgaEXTENDER aim is exactly the opposite, so dont worry.
-
- Oh oke, but see above..
-

- Pheeww... ;)

- I missed Cyberman here I think.. never heard of it.. VK was nice on a basic
- A1200. But I've got a A1200 Blizzard IV with 4mb fast... :/

- Really looking forward to VR and SF.
-
- Btw.. I'm also developing a Game, see my sign..
