About the computational power of g4 machines
Hi.
I have the opportunity to buy an iBook G4 800MHz so that i can continue
working with Debian + PowerPC.
I have two questions, which I list below.

I depend on the questions above to get myself an used ppc box so that I
can use it in, say, Debconf 9 (let me cross my fingers).

Right. I thought it would be hard to see. But how much not viewable is
it? Are you using mplayer? Do you have many frame drops?
720p is perfect.
Can you test the 720p video with a lower clock? I'm interested to see
how low can its clock go while still watching the video. If you can
please use the following:
* the userspace governor (so that you can change the frequencies as you
please);
* try using powerprefs, if possible.

No, I don't play any games. I was just interested in knowing if the
hardware could cope with some things like avant-window-navigator (which
seems to need compositing).
Also, how is Airport Extreme working with the binary blob and current
kernels?
Used Powerbooks are unbelievable expensive, even my 5 year old PB
(ebay: over 500 € still, you get a first class used PC notebook for
that amount). The used Apple Notebooks seem to be a pretty good
investment ;).
Unfortunately, my budget is limited. This is the reason why I would like
to know better before I actually get a ppc notebook (the primary reason
would be Debian development and getting Linux working on some ppc
boxes).
I'm also thinking of reviving gtkpbbuttons, pbbuttonsd etc, if I do get
a good laptop.

Yes, it uses ATI's proprietary MPEG acceleration, which specs never were released. It was the same on x86, for the same class of machines. Only Intel gave an open source driver with used the same functions on his 810 hardware and NVidia brought that for Linux in a closed source way for his Geforce 4 series. -- To UNSUBSCRIBE, email to debian-powerpc-requ...@lists.debian.org with a subject of unsubscribe.
