I won't ship so please don't ask. 1.) Many SCSI cables (mostly the older fat ones, some combination, some smaller). 2.) Few BNC connectors 3.) SCSI terminators (old fat ones) 4.)

  • 3. Creating a Mac/PC compatible (Mozilla) mail archive CD
    Having stored my email throughout the years on CD I'm now in the process of trying to organize things so they'll be more compatible with both PCs and Macs, and could need some advice on how to work this out. I've been using Eudora on a Mac for years, which stores email in the MBOX format. I'm currently using Mozilla (1.7.5) on a PC which also uses that same MBOX format. A couple of issues come to mind for cross platform compatibility: 1) Line endings. Is this an issue, or won't Mozilla care? If it does care, is there a line-ending type that will work for all platforms of Mozilla (Linux, Windows and Mac (Classic and OSX)? 2) Character set. For non-English characters, should I convert my existing email to a particular character set? I believe my Eudora mail is converted to the Mac character set, but I'm not sure. Obviously that'll be all wrong when i read it on the PC. Does Mozilla rely on a specific platform's character set, or does it stick to ISO standards, meaning that non-English characters will look the same on any platform runnin Mozilla? Anything else to keep in mind for a project such as this? -- Hallvard

  • 5. can't install OS10, confused
    Can someone help me understand this. Own a Wall Street that has served me well and faithfully under OS9.2. Picked up a new HD (10gb Apple branded) and a copy of OS10.1 at a secondhand store. Figured it was a good way to upgrade the storage and OS in one move. Formatted the drive with Drive Setup on the CD and then cloned my old OS9 disk onto it. Boots and runs fine. When I try to install 10 it will show the new drive as a greyed out option and proceed no further. If I put the old drive in, it sees it and will allow the install. Anyone have any advice or tips? Thanks in advance. MAH

Powerbook 12" Superdrive and noisy fan

Postby vphooff » Thu, 28 Apr 2005 09:17:22 GMT

i just received a Powerbook 12" SuperDrive 1.5GHZ + 80GB harddrive
I can't believe how NOISY it is. I had a white G3 iBook for a long
time. What a difference! It seems that both the fan and the harddrive
are louder. I installed TEMPEROX
( http://www.**--****.com/ ) to check if
everything was ok and here is what i get while writing this:

CPU Bottomside: 43.25/109.85
CPU Intrepid Bottomside: 44.5/112.1
Power Supply Bottomside: 48.25/118.85
Rear Left Fan Speed: 3734.9 rpm
Rear Right Fan Speed: 35.0 rpm

Can anyone tell me if this is normal. I'm a bit worried about the Rear
Left Fan Speed. It's up and running almost all the time. Is that
normal?

Thank you for any help!

Sounds a bit wrong to me. I have the 1.33GHz PB 12" and don't ever recall
hearing the fan (I think it has come on, I just can't recall any specific
incident). Here's what Temperox gives me:

CPU Bottomside: 30.5
CPU Intrepid Bottomside: 28.25
Power Supply Bottomside: 39.5
Rear Left Fan Speed:  0.0 rpm
Rear Right Fan Speed: 23.0 rpm

Much quieter than yours. I've only just woken it up though, and is a slightly
slower model, but still...

Any rogue processers going haywire? Check Activity Monitor and see if some
process is maxing out your processor.

And after a couple of compiles and other fairly typical usage:


Significantly higher temperatures (but still not quite as high as yours,
particularly "Intrepid") but no great increase in fan speed.

And finally, after stressing it good and proper by ripping a CD and playing it
at the same time, while compiling and debugging an application:

CPU Bottomside: 60.25
CPU Intrepid Bottomside: 42.75
Power Supply Bottomside: 61.5
Rear Left Fan Speed:  0.0 rpm
Rear Right Fan Speed: 31.0 rpm

During this time the CD drive got a bit noisy, but I still couldn't hear the
fan or hard drive.

BTW, this is not plugged into the wall, which may make a difference.

Thank you.
I just upgraded to TIGER & did more tests with Activity Monitor &
Temperox,
have a look:
 http://www.**--****.com/ 

Right now I'm just hoping that the PowerBook will end-up finding the
right settings by itself. But it is quite hot on the left side, and
that's probably why the left fan only is spinning like crazy :(
It's a Ti Powerbook 1,5GHZ, G4, 1,25GB SDRAM, 80GB HD (TOSHIBA
MK8026GAX)

Is there any point in running a check disk or something?

Thanks for more advices.

Wait a second

My 15" 1.5Ghz is reporting this :

PowerBook5,6
----

CPU Bottomside = 44.5C
CPU Intrepid Bottomside = 46.5C
Power Support Bottomside = 41.5C
Battery Temperature = 33.5C
---
Rear Left Fan Speed = 0.0 rpm
Rear Right Fan Speed = 0.0 rpm


Surely my fans should be at least moving with those kind of temperatures??

Maybe not.  The G4 chips are rated to run at something like 65C, none
of your temperatures are close to that.  Not certain of what the cut
in temperature is, one place I read that it was 45C and another said
50C for the fans.

1.Noisy fan on Powerbook G4 (follow-up)

2.Replacement for noisy G4 Powerbook fan?

I bought a 15" Powerbook G4 (1.67GHz, Superdrive) a little over a year
ago, which probably means that my warranty has expired, which in turn
means that I can do anything with my machine ;-)

One slight (sometimes more than slight if I run "heavy" tasks for
extended periods of time) is the (IMHO) rather noisy cooling fan inside
the computer.
I'm sure Apple didn't pick the quietest fan around (more likely they
picked the one they could get the best deal on), so I'm wondering if
there are better replacements available with the same size, voltage,
effect etc?

3.New 12" PowerBook - Combo or Superdrive?

Hi,

When I go to Apple's site it looks like the only difference between the $1599
and $1799 models is the superdrive.  Is it worth the extra $200?  I don't plan
on burning DVD movies but it would be nice for backups (1 or 2 DVD-Rs instead
of a bunch of CD-Rs).  How much data can you store on a DVD?  If you fill the
DVD, how long does it take to burn?

thanks
Jeff

5.12" Powerbook fan always on

I have a first generation 12" powerbook g4 and i'm getting the urge to 
smash it with a bat.   Back when 10.3.4 was released, Apple updated the 
kernel extention that controlled the fan and caused it to start at a 
lower temperature.  I was annoyed that the fan was always on so i used 
the kext from the 10.3 CD and replaced it.

All was good until 10.3.8 was released and Apple updated the kext again 
and now the fan is always on.  Going back to the old kext really isn't 
the solution because the same thing will happen in 10.4 and the old 
kext wont even be compatible with the new kernel.

The most annoying part is that this powerbook doesn't even feel any 
cooler, it almost feels warmer.  I'm wondering if this is a common 
problem for first gen 12" powerbook g4s or if there is a convenient fix 
(not for just the fan, but the heat issue).

This thing gets so hot, that simply typing this message caused my palms 
to get all sweaty from resting on the cover.
