You'd still need an original Pismo processor for the upgrade, though.  
The upgrade companies modify the original processor, unlike the  
Powermac CPU upgrades, where they give you a whole new processor.


If you go for a G4, both Fastmac and Daystar are good.

P.S. Actually, Daystar will also sell the whole G4 processor. You get  
a G4/550 for $399, which is VERY expensive. The upgrade to your  
existing processor costs $289. Before spending $399 on the whole  
processor, though, plus RAM and HD and optical drive (1GB RAM +  
40-80GB HD + Combo or Superdrive = $300-400), I'd consider a used  
Titanium, which you can find for considerably less than the upgraded  
Pismo would cost you.

Hi Dan,
Sorry no such luck ... current temperatures output from Temperature 
Monitor
are 88C (190F) and 39C (102F) for the 400Mhz CPU and the SMART 40GB
Travelstar Drive, respectively. Before the CPU was replaced under 
AppleCare
the old 400Mhz CPU was listing at around 30-40C (less than half as 
much).

I suspect it might be a calibration problem for the TAU and that the 
temperature
output on this new CPU bares little resemblance to reality (but I just 
want
to make sure as temperatures of 90-105C are a little warmer than I 
would like).
Perhaps the new IBM CPU isn't calibrated as well as the old part.
A PDF at the site (sorry about the long broken URL):
www-306.ibm.com/chips/techlib/techlib.nsf/techdocs/
730050B2CD2C7C8487256ADD0061F729/$file/TAU_Calibration_10s.pdf
indicates the lengths necessary to get a PowerPC 750 TAU calibrated.

So far my Pismo has been running fine for a couple of weeks so perhaps 
it
is not a real problem ( I hope ..).

Thanks,
Harry.

Pismo Processor Temperature: What is normal?

2004-07-25 Thread Hoju Han
Hi Folks
Surprisingly, all the replies to my previous detailed Email
(i.e. www.mail-archive.com/[EMAIL PROTECTED]/msg19147.html)
have not addressed my main query (which I repost here in abbreviated 
form).

My PowerBook Firewire G3/400Mhz had to have the 400Mhz processor module
(661-2386, P3589) replaced (I COULD TRACE DOWN THE FORMER NUMBER; BUT 
WHAT
DOES THE NUMBER P3589 MEAN?) to solve its booting/sleeping problems
(i.e. www.mail-archive.com/[EMAIL PROTECTED]/msg18290.html)

Previously, temperature monitoring (using the TAU on the PowerPC 750) 
indicated
a temperature of around 30-40 Celsius. However, with the new CPU 
installed,
I am getting CPU TAU readings of 90-114 Celsius (The internal IBM 40GB 
GN
Travelstar disk with SMART monitoring has temperatures of 25-45 
Celsius).

The original processor in the Pismo was maybe a previous generation
(DO THE NUMBERS IN PARENTHESES INDICATE GENERATION?) with the 
designation
PowerPC 750  (83.0) 400Mhz while the currentnprocessor has
an updated numbering: PowerPC 750 (83.2) 400Mhz. COMMENTS?

I believe that the Pismo uses IBM PowerPC parts (since the Motorola 
equivalent
is called an MPC750) so perhaps:

1) what I am seeing is an inaccurate uncalibrated number for the CPU 
temperature
and it is indeed running at a much lower temperature (e.g. 40 Celsius).
2) However the link www.xlr8yourmac.com/tips/G3_temp.html mentions that
it is possible to install the heatsink on the chip with poor thermal 
conductivity.
So it could be that the CPU is running hot due to poor installation.
IS THIS REASONABLE? SHOULD I GET THE APPLECENTRE TO REINSTALL WITH 
THERMAL PASTE?

I am thinking of checking with the AppleCentre where I hope I can speak 
to the
technician who did the reinstall. Or should I just happily use the 
laptop till
it fries. Externally the Pismo doesn't feel much hotter than normal 
(the base
of the unit is always the warmest part).

QUERY: Could all those folks with PowerPC 750 chips (400/500 Mhz) in 
their
laptop use a Temperature monitor (Thermoindock, Temperature monitor) to 
give
me a ball park idea of how much these readings can vary?

Thanks,
Harry.

Don't worry.
You can buy a Panasonic mechanism as an upgrade for
your PowerBook.
It's cheaper than sending your DVD Drive to an Apple
dealer to get another LG one ;-)
Here's the link.

Pismo Processor Module Replacement, High Temperature?: Sequel to Pismo Sleeping/Booting Saga

2004-07-23 Thread Hoju Han
Hi Folks
I hope these escapades prove informative (and hope this mail finally 
gets through!)

This is a sequel to my previous Emails (Pismo Sleeping/Booting Saga)
(e.g. www.mail-archive.com/[EMAIL PROTECTED]/msg18290.html)
about my PowerBook G3/400Mhz which wasn't reliably booting and sleeping.
Fortunately I had AppleCare extended last November (2003) for two more 
years
(A$384). Since then the DVD drive has been replaced twice (yes the 
reliable LG
DRN-8080B) and now I have had to deal with this current repair.

In short, it turns out, that the 400Mhz processor module (661-2386, 
P3589) had to be
replaced (I could trace down the former number but the latter number 
P3589 seems
mysterious!) which then solved the booting/sleeping problems; not my 
first guess
since the Pismo was running reliably otherwise.

Anyway, I had been playing with temperature monitoring (since the 
PowerPC 750
can estimate temperatures on the chip due to its Thermal Assist Unit 
(TAU)) and
had been largely using ThermoInDock (but also the excellent Temperature 
Monitor
(www.bresink.de/osx/TemperatureMonitor.html).

Normally these temperature monitors (using the TAU on the PowerPC 750) 
indicate
a temperature of around 30-40 Celsius (sometimes a little more if the 
CPU is busy).
However, with the new CPU installed, I am getting CPU TAU readings of 
90-114 Celsius
(I also have an IBM 40GB GN Travelstar disk with SMART monitoring with 
temperatures
in the range of 25-45 Celsius, of course on chip temperatures may bear 
no relation).
Ambient air temperature is about 20 Celsius (inside with the heating 
on, it is Winter here!)
Some samples:

2004-07-23 13:42:05 +1000 92.00 43.00
There is a huge caveat regarding the TAU accuracy:
Some older G3 or G4 systems can be equipped with processors containing 
a so
called Thermal Assist Unit (TAU). This is a technique to acquire 
temperature
values directly on the chip die and compute it by the processor itself. 
However,
this technology is very inaccurate and only works correctly if each 
processor is
calibrated. Motorola specifies that the readings supplied by such 
processor
types can be off by 12 degrees Celsius (21,6 degrees Fahrenheit) from 
the actual
values. For IBM G3 processors there can even be a difference of 20 
degrees
Celsius (68 degrees Fahrenheit) between the measured and the true 
values. Due to
this problem, the processor manufacturers have disabled the TA Units 
for later
product generations. Up-to-date versions of the G4 series no longer 
support
temperature measurement on the chip die. Here, real sensors have to be 
used.

The original processor in the Pismo was definitely a previous generation
(if the numbers in parentheses indicate generation) with the designation
PowerPC 750  (83.0) 400Mhz (I think, year 2000 vintage) while the 
current
processor module has an updated numbering: PowerPC 750  (83.2) 400Mhz. 
Ideas?

I believe that the Pismo uses IBM PowerPC parts (since the Motorola

Re: Pismo Processor Module Replacement, High Temperature?: Sequel to Pismo Sleeping/Booting Saga

Well, I can talk about the DVD Drive only.
Some Pismos came with the LG Scrap DVD and the rest
with a Matshita one.
Matshita is a division of Matsushita, which makes
Panasonic, National and Technics products.
I saw that the LG DVD can be replaced with a Panasonic
one (Matshita).
Here's the link:

http://www.wegenermedia.com/pismodvd.htm

If you send your PowerBook to an Apple Service, they
will replace the DVD Drive with a same brand as the

people told me, because they still have a lot of stock
of LG DVD Drives.
They will only give you a Matshita drive if you give
them a similar one.

This is true. Alas, when my Pismo's dvd drive had problems, they 
replaced it with the same old LG :(
So far, so good. I don't use it a lot, though. Now my Applecare is 
buh-bye.

Re: Pismo processor

2003-10-20 Thread Thomas Ethen
I have a question for the list about switching processors in a Pismo. I have
acquired a 500MHZ G3 processor and want to exchange it for the 400MHZ
processor I now have in my Pismo. Is it a simple exchange, or do I have to
something other than just switching them?

Difference in Pismo processor 1 and 2

2003-10-17 Thread Geoffrey Loeffler
Can anyone explain the difference between the revision 1 and revision 
2 processors in a Pismo 500 and how to identify the difference, are 
they interchangeable, is one more prone to problems then the other 
and any other bits of knowledge that may enlighten my journey to 
rebuild a Pismo
Thanks
Geoff
