Thanks to these two:

http://www.pegasosppc.com/odw.php

and

http://www.gvs9000.com/workstations.html

and others, we will continue to have non-Apple PPC
workstations and servers, but what about non-Apple PPC
laptops?

How soon you think we will get one?

Personally I'll never get one ... well, not until someone makes a hack
that lets you use the Mac OS on it. :-)

the first url looks like a slower and more expensive mac mini: 1gz g4,
80g hd, dvdr, all for just $799 or just the motherboard for $499.

the second url appears to be a rebadged mac which can run osx (and
looks like it ships that way too):

http://www.gvs9000.com/gvs90002ug5spec.html

Running on the most powerful operating systems in the industry, Mac
OS X and Linux, GVS9000 G5 offers users the utmost in expansion
capability

it even has an optional airport extreme card!

and this model even runs os 9 in addition to osx (and linux):

Probably not. There have been a couple companies selling rackmountable
servers using motherboards from Apple for several years.

Copyright law forbids you to make copies of a copyrighted work without
permission and for purposes that are not covered by your right to

I don't know if any US law says that you must accept an agreement you
did not sign and didn't read before you bought the product.

I know that such "licence agreements" are not enforceable in the EU.

I won't have a problem running Mac OS X on a non-Apple PowerPC box. If
Apple want to stop me, they will merely use a customer for both their
hardware and their software. It's their choice. It should be mine.

The Mini's pretty competitive with this. But a look at
<http://www.pegasosppc.com/pegasos.php> shows the Pegasos box has a lot
more in the way of ports & expandability than the Mini. Whether that's
important is an individual decision.

But... laptops? I wouldn't bet on it. Even aside from technical
considerations, it really doesn't look like either of these companies
would be interested.

The other nice thing I am noticing with the Pegasos is that $799.00
is €650.00, much unlike Apple where $499 is €539 (for the same
configuration mac mini)

Well, it is not a competition (yet). Besides, this is just the first of
many (I hope)

Well, they started like that. But they will keep the design and
continue making

Riiiiiiiiiiiiiiiiiiiiiight.

You appear to be arguing that Macs should still be running Motorola
MC68K-family processors.

Riiiiiiiiiiiiiiiiiiiiiight.
No kidding.

I didn't buy this iBook because it had a G4 in it. I bought it because
it runs Mac OS X, has iDVD, and because every other attempt to do what I
want to do with PC's as regards DV processing (making quicktimes for the
web and home movies for the extended family) resulted in frustration,
anger, depression, and general annoyance, since better DV software for
the PC was going to cost me money.

Frankly, if I had to spend money on DV stuff, I knew an upgrade was in
the cards to replace my ageing Dell, and the Mac comes very highly
recommended by people who do DV around me. Also, I wanted a Unix-like
environment, but I absolutely am tired of all the tinkering and messing
around one has to do to get Linux running on all cylinders. I want it to
just work, y'know!

It doesn't freaking matter what *processor* is used, if that's the
thinking. Heck, with gcc and X11 on board (someplace) as well as a
number of very sweet development tools, I can now run anything the Open
Source community makes, if I want.

All the geeking out I've been doing since then about iLife and Expose
has been just a nice bonus.

IOW, it was all about the software.

No. PowerPCs are descendants of the CPUs IBM used to use in their
RS/6000 workstations. Those CPUs were later known as the POWER
architecture. The m68k is unrelated. This is the main reason why the
switch from m68k to PowerPC was such a big deal in the Mac world-- it
was an entirely different architecture.

Ah, got it. I remember the RS/6000's. Nice hardware for its time; nasty
OS. With a NeXT cube sitting right next to it I almost never used the IBM.

Actually, POWER was the name in the RS6K, PowerPC was derivative of it.
The first PowerPC was faithfull to the full instruction set, later
models dropped some instructions and started breaking things.

So, just to be clear, it was not 'later known as'.

Wikipedia is one of the growing number of useless "reference" websites
that have all their information supplied by the user - some people
think it's funny to add stupid and incorrect information on purpose,
others simply add rubbish they've read elsewhere on the 'Net which
turns out to be nothing but rumour.

Wikipedia is (supposedly) tightening up control on what is added. Now
if only the others, epecially the hopeless IMDB.com would do the same
they might actually be useful websites.

Yes, it seemed to accept an edit to move the most offending stuff, and
now I see it is back to the original.

To wit:

"It is noteworthy that this architecture was originally called "PowerPC"
by IBM, the term "POWER" was coined several years later to differentiate
between IBM's server-oriented processors and their desktop and embedded
processors."

My first RS6K was a 7012-320. It said POWER. This was not a name later
invented. POWER did not differentiate between servers and workstations
as the most powerfull server at one time, the 7013-J series was PowerPC
based.

I have created an account, and may try to correct it again, but it is
unfortunate such rubbish gets put out there.

Not really. The PPC has many elements of the 68k and even comes with a
68k emulator
built-in the chip itself. The move to 68k to PPC was fairly easy thanks
to the nature of
the PPC. Going from PPC to x86 will not make possible CRUCIAL things of
the Mac OS, like Classic.

its very possible to have classic on intel, however, the question is
whether it is worth the effort to bother. the number of people who
need classic is dwindling, and by the time intel macs are common,
classic will be even *less* important than today.

Crucial to some, perhaps, but not me. I've never even run the Classic
environment on my PowerBook. If anyone cared enough, it would be just
about as simple to write a 68k emulator for x86 as it was for the PPC.
Easier, since the speed difference between the fastest 68k shipped in a
Mac and contemporary x86 processors has increased so much.
(A bit of quick googling brought up this:
http://www.squish.net/generator/, which looks like a fairly promising
place to start (dynamic recompilation and all...))

There's one big difference that make 68k emulation far more efficient on
PowerPC: as PowerPC is a RISC processor and m68k is not, you can keep all
m68k emulated registers in PowerPC registers. When emulating on a x86, you
have so few register that you need to store the whole emulated CPU in
memory. This may slowdown the emulation with a 2 or 3 factor.

The Mhz difference will be compensated by the low efficiency of the CPU.
x86 is really not a great platform to emulate other CPUs. x86_64 is a
little bit better...

PowerPC has nothing related with 68k. The only one common point is
endianness. The only part of PowerPC which is related with previous
Motorola CPUs is its bus which was inspired by the one used on 88000 (not
68k !).

Apart of this, no element of the PowerPC architecture come from m68k or
m88k.

And m68k emulation has always been done by software on PowerPC machines.
There is absolutelly no hardware facilities for such a thing.

I know, I know. You guys misinterpreted what I said. What I meant was
that (as you know), the PowerPC architecture has a group of
byte-reversing load and store instructions which can be useful for
emulating little-endian 68k processors on a big-endian PowerPC system
(such as the RS/6000 and Power Macs). That's all I meant.

that (as you know), the PowerPC architecture has a group of
byte-reversing load and store instructions which can be useful for
emulating little-endian 68k processors on a big-endian PowerPC system
(such as the RS/6000 and Power Macs). That's all I meant.
Hum...
m68k is _big_ endian, like PowerPC.
Then, byte-reversed load & stores are not usefull for m68k emulation on
PowerPC.
Those instructions are mostly used to access devices, like PCI ones, which
mostly are little-endian by nature.
It can also be useful when reading data provided by little-endian archs,
like IBM PC, but those cases are less time critical.
And it make x86 emulation on PowerPC more efficient, for sure.

Not really. The PPC has many elements of the 68k and even comes with a
68k emulator
built-in the chip itself. The move to 68k to PPC was fairly easy thanks
to the nature of
the PPC. Going from PPC to x86 will not make possible CRUCIAL things of
the Mac OS, like Classic.
PowerPC has nothing related with 68k. The only one common point is
endianness. The only part of PowerPC which is related with previous
Motorola CPUs is its bus which was inspired by the one used on 88000 (not
68k !).
Apart of this, no element of the PowerPC architecture come from m68k or
m88k.
And m68k emulation has always been done by software on PowerPC machines.
There is absolutelly no hardware facilities for such a thing.

Aren't the G4's and G5's descendents of the MC68K family?
No. PowerPCs are descendants of the CPUs IBM used to use in their
RS/6000 workstations. Those CPUs were later known as the POWER
architecture. The m68k is unrelated. This is the main reason why the
switch from m68k to PowerPC was such a big deal in the Mac world-- it
was an entirely different architecture.

Actually, since the Rosetta / Transitive system can supposedly
"translate" code from ANY chip to run on ANY other chip with "no speed
penalty", it should be extremely easy for an IntelMac to run Intel
code, PPC code, 680x0 code ... hell, even 6502 code, etc.

Even without that it would be possible, albeit at a slower speed. In
fact it's almost certain that some emulation coder will get something
working eventually, even if it's 10 years time for nostalgia purposes.

The only reason Classic MAY not make the transfer to IntelMac is
because Apple doesn't want to bother doing it, just like they stopped
adding floppy drives, using ADC, updating Mac OS 9 and other Apple
software for non-OS X Macs, etc., etc.

Riiiiiiiiiiiiiiiiiiiiiight.
No kidding.
I didn't buy this iBook because it had a G4 in it. I bought it because
it runs Mac OS X, has iDVD, and because every other attempt to do what I
want to do with PC's as regards DV processing (making quicktimes for the
web and home movies for the extended family) resulted in frustration,
anger, depression, and general annoyance, since better DV software for
the PC was going to cost me money.
Frankly, if I had to spend money on DV stuff, I knew an upgrade was in
the cards to replace my ageing Dell, and the Mac comes very highly
recommended by people who do DV around me. Also, I wanted a Unix-like
environment, but I absolutely am tired of all the tinkering and messing
around one has to do to get Linux running on all cylinders. I want it to
just work, y'know!
It doesn't freaking matter what *processor* is used, if that's the
thinking. Heck, with gcc and X11 on board (someplace) as well as a
number of very sweet development tools, I can now run anything the Open
Source community makes, if I want.
All the geeking out I've been doing since then about iLife and Expose
has been just a nice bonus.
IOW, it was all about the software.

You appear to be arguing that Macs should still be running Motorola
MC68K-family processors.
Pretty silly.
Aren't the G4's and G5's descendents of the MC68K family?
No, almost a clean-sheet development with Apple, IBM and Motorola all
contributing. It's closer to IBM's POWER architecture than to earlier
Motorola work.

That is not what I meant. The PPC is a better 68k in essence. The 68k
was a better CISC
tech than x86, and PPC even comes with a 68k emulator (built-in the
chip). The
transition of 68k to PPC was a natural one. Going from PPC (a clear
better tech, ie. RISC)
to x86 is like going from a Flat Panel TV to a CRT, just because CRT's
may look better
for non-HDTV signals.

They are never been any PowerPC with built-in 68k emulation.
There was rumors about a PowerPC with x86 emulation (the 615), but no
actual PowerPC chip has ever integrated such an hardware emulator.

???
Have you ever tried to work with HDTV signals on flat panels ?
For now, Flat Panel TV are ugly and most are unable to display TV
correctly, ie, without digitalisation artefacts and video processing bugs.

This comparison is complete nonsense....

Better architecture, almost certainly. Improved 68K? Not even close;
they're completely different architectures.

Well, *that* certainly explains why Apple spent all those resources
(time, money, engineers) writing the 68K emulator so that their new
PowerPC systems could run existing Mac OS applications.

Where do you *get* this stuff?
Post by abpp
The transition of 68k to PPC was a natural one.
It only seemed that way because it was implemented so well. There was a
huge amount of work required to make it look so easy and seamless. (In
retrospect; at the time there was no little screaming from a few because
it wasn't completely perfect from the start.)

As it turns out, Motorola's 68K successor architecture, the 88K, flopped
in the marketplace; they didn't have anything to offer until they
started shipping PowerPC CPUs that grew out of the AIM alliance, and was
based on IBM's POWER architecture.

PowerPC is no longer pure RISC (according to the original definitions of
Cocke at IBM, and Patterson at Stanford), and Intel's CPUs that will be
shipping in upcoming Macs are not pure CISC, even if they look much like
CISC from the outside.

If you can get as good, or better, performance from a CPU at lower power
consumption and equal or lower cost...it's going to be hard to sell the
idea that it's inferior.

And if the end product runs the better OS/applications such that the end
user can't tell which architecture is running, then you're argument
comes across as more than a little weak.

But if you want to be a True Believer(tm), don't let anyone stand in
your way.

Since Apple ARE switching to Intel and WILL stop development of PowerPC

completely pointless having a computer just because it has a PowerPC

Hmm, so its pointless to buy a iMac or iBook, anything mac too.

While being completely against intel decision, I don't think Apple will
drop ppc OS X that easy.

Well.. I hope. It doesn't mean if it happens, I will go and cry to
Apple. I will donate this g5 desktop to a school/university and move to
AMD64+Windows.

freebsd doen't support ppc architecture.
they will in the near feature but now
this project is quite fresh.
