fullcontactmuse: (The Server Is Down)
Thanks to [livejournal.com profile] corwynofamber, [livejournal.com profile] qijm, and [livejournal.com profile] urbanwolfie, for their insights.

Getting the memory out of the iMac was perhaps the easiest configuration I've seen. Seriously, there is a port of the back that unlocks with a flat head screwdriver, and opens up to expose two DIMM slots and the AirPort (Apple's wireless NIC) recepticle.

The 64mb stick by itself caused a boot failure in the Mac. Ick.
The 128mb stick worked, but Starcraft still failed with it's mysterious error.

Digging through my computer graveyard, I found a 512mb PC133, a 256mb PC133 stick, and 2 unidentified DIMM's look the same as the PC133 256mb stick of memory.

The 512mb stick works fine and the Mac is running a little faster now with just that installed. It's that whole diet memory for modern operating systems. I haven't tested any of the other sticks that I found yet.

Crash details for those who are interested )

I was given an iMac G3-400 (I'm not sure of the specific model) and I have a couple of questions about the memory in the system.  Here's the Hardware Overview from System Profiler.
    Machine Model:      iMac
    CPU Type:           PowerPC 750 (83.2)
    Number of CPUs:     1
    CPU Speed:          400 MHz
    L2 Cache (per CPU): 512 KB
        Memory:             192 MB
        Bus Speed:          100 MHz
        Boot ROM Version:   4.1.9f1
        Serial Number:      TM0402B0JAU
 
I had recently purchased a second copy of Starcraft for my son, one with the Mac binaries on it as well and installed it using the Mac OS X installer for Starcraft from the blizzard.com/support website.  However Starcraft blows up on launch.  So I queried Blizzard tech support, sending them the System Profiler output and the crash log, and waited.  And waited. 
 
In the mean time, I installed Bejeweled 2 Deluxe.  It does something similar, it loads, the screen goes black, and then it exits. Huh.
 
I hear back from Blizzard and their answer is "Remove the third-party RAM and try again.  The RAM installed in the system is not even the correct speed."
 
Previously, I had investigated when the iMac will take in terms of a memory upgrade and found that it takes 2 PC100 SDRAM sticks up to 512mb a piece.  So I go look in the System Profiler again at the memory configuration.
    DIMM0/J13    64 MB    SDRAM    PC100-322S
    DIMM1/J14    128 MB   SDRAM    PC100-222S
 
Here are my questions:
1) Would someone confirm that PC100 memory is the correct speed for this iMac?
2) Both sticks are PC100.  What is the 322S and 222S markers in the speed column?  I've never seen that before in the PC world and have no idea what it means.  Could someone elaborate on that?
3) How much memory did this iMac ship with in the default configuration?
4) Is there any issues with having the smaller stick in slot 0?
5) Before I go bumbling my way through cracking open my iMac, are there any tips for do so.  While I have mucked about and built many a PC, I tend to stay away from CRT monitors.

...with OS X. Mind you, it's kind of painful in the performance department, but I don't really blame the OS for that. I blame the 6 year old hardware running OS X. :)

I am looking for some 168 pin PC-100 SDRAMM for the iMac I acquired. Presently it has 192mb of RAM, but I will like to take it to 1gb (2 x 512mb). Does anybody have any spare RAM lying around that they wouldn't mind donating? :)

I recently came in possession of a G3 iMac and I have questions. First of all, it's been 15 years since I've seriously fiddled with a Mac and it's changed substantially in that time. Ultimately, I want to be able to get it to the point of being able to run OS X.

Here's what I've been able to determine about it:
  • Mac OS 9.1
  • PowerPC G3 400 mhz
  • 192mb RAM
  • 8mb AGP video card
It looks like it uses SDRAM PC100 memory and take two 512mb sticks, which would cost me about $140 or so. Does anyone know if the video card is replacable?

I got the iMac from a from a friend at Norwescon so I could test the online apps against a Mac. If I can get WoW to run on it, it would make my daughter very, very happy. She's already in love with the bright blue computer...
