Thanks, Derick.
Although this is a YDL forum, I am afraid to say that there is no
comparison between any linux on PPC and OS X. The former simply
doesn't have the software base that I need. I used to think that it
would be faster than OS X, but after a few installations of linux on
Apple computers, I discovered that OS X wins hands down in the speed
area as well. I think that linux is optimized for x86 and of course
things like flash are only available on x86 linux (I hate flash, but
it unfortunately has become a standard for internet video). There are
still some PPC optimizations in OS X apps and maybe even some Altivec
usage (which allows Quicktime to smoothly run at 1080p on my PPC
machines). The tasks involved in writing my book would have been
enormously greater if I had used linux instead of OS X.
I notice an increasing dominance of ARM in low power portable devices.
This is unfortunate, since ARM simply doesn't have the computational
power that PPC has - I am not sure it even has a floating point data
type. It is too bad that IBM did such a poor job of promoting PPC; we
will need to reinvent the wheel with ARM when we could have had
advanced multi-purpose chips with low power consumption from the PPC
manufacturers (such as PA semi, which Apple bought and converted to
ARM).
Anyway, the improvement in the performance of Apple products since the
switch has been less than stellar, much less than expected from
Moore's law. My 4 year old G5 has a 1.15 GHz memory bus and an 16x
dual layer superdrive, which is very competitive with the best that
Apple can come up with now (for reasonable prices). It cost much less
than a current machine and doesn't require a several thousand dollar
investment in software, which I would need to make if I use one of
Apple's intel superboxes.

I think we may have to really keep our PowerPC running for longer than
that although I did hear of someone developing a multicore PowerPC
laptop a month or so ago. I've got to search for who this fellow is
again as I lost track, but I did hear of a fellow who created a
working
Cell based laptop which ran the GameOS and had the OtherOS option.
Pretty neat!
Caveat: If you replace the power supply or other support parts you
shouldn't have trouble running YDL from it. Be careful regarding
other
components however such as DVD drives: if those go it may be wiser to
consider an external DVD drive in that situation. I'm unsure if
anyone
we knew remains at Fixstars from TSS; it may not be so easy to get the
kind of support we became accustomed to. In any case, I'd advise you
to consider reviewing what notations remain regarding their advisories
regarding which hardware works with YDL and which do not. As best I
recall, the past emphasis (by TSS) was to support original Apple
parts.
So the problems to watch for may not be RAM as much as internal
associated devices, such as a newer hard drive or modem or something
similar. It may be better to just get an HD which resides on a PCI
card which your system should recognize with no problem as an external
system; I don't think such a drive would be able to be booted from
within YDL. It would be interesting to try that out as a concept
though.
Anyway enjoy and all the best!!

Thanks, Derick. I still love the PPC architecture and recently
bought an Apple dual core 2.3 GHz G5 for very little money and am
finding it to be absolutely as fast as I could ever hope for. I will
keep it for the next 3-5 years (assuming I can keep the power supply
running) and maybe then, the dominance of x86 may have lessened (it
can't last forever!).
Merry Christmas and Happy 2010,
