I am new to the apple discussions.
I bought 2 imac g3 machines for my grandchildren 4 & 6 yr old.
I want to upgrade them and connect to the internet. I do not know where to begin to even tell you what the capacity of the machines are.
Please help in getting me started. I know nothing about macs. I think these machines are ideal for them and like the bright colors.
I am also willing to get repair for not to much money in Boston MA.
Can anyone help????????

imac g3, Other OS

    Hi!

    Well, the first thing is to make sure that they actually turn on and display something on the screen. If you hear the "chime" when they're powered up, that's a great sign.

    Next, to figure out what operating system they're running.

    If they're running a "Classic" Mac system such as OS 9, they will start up with a face on the screen, and eventually, when they boot up to a desktop, you'll see a rainbow-colored Apple logo on the very top left.

    If they're running Mac OS X, you'll see the Apple logo when it starts up, and then the desktop will have a solid blue apple in the top left.

    Let us know where you get to, and we can help you from there!

    Hi,
    I am so excited to get help for my grandchildren.
    Thanks to all.
    after turning on the machine and determining that it is os 9.2 with a rainbow apple in left corner, I found info on the system config.
    MM521, memory disk 4096k, virtual memory 128mb, built in memory 128mk, backside L2, 256K, machine speed 500 mhz.
    I hope this further helps for help on the way.
    Thanks

    Hey vw,
    First are these slot loaders or tray loaders?
    http://www.lowendmac.com/imac/guide.html
    http://www.lowendmac.com/imacs/index.shtml
    http://www.apple.com/support/imac/g3/

    Next what version of firmware are they running?
    http://lowendmac.com/macdan/md07/1207.html
    You can also look under the Apple-system profiler-production information. It should say 4.1.9 but probably says 3.0f something something.
    If you move the machines to 10.2 you must update the firmware first and this has to be done from OS9.

    That will also tell you how much RAM there is in there and how big the hard drives are.
    For OS 9 128 - 256 RAM is ok for OS 10.3 and higher I'd recommend 512 to 768. Depending on what you want to do the hard drives should be at least 10 GB or above.

    I set up a lot of these iMac G3s for kindergartens up to high school. For the lower grades I use OS 9 and load a lot of games and things like Living Books.
    For the upper grades that will be on the net I use 10.4.11 with at least 384 RAM. At that level they will actually run Garage Band,

    Hi again

    That's great info! The important numbers are:

    Your computer's CPU - its main processor - has a speed of 500MHz.
    You have 128MB of RAM.
    You probably (although you don't mention it specifically) have a 20-30GB hard drive.

    You have what Apple called a "Slot-loading iMac". (The slot refers to the appearance of the CD/DVD drive slot.) You will need one more piece of information: what kind of CD or DVD drive do you have? Turn the computer upside down and you should see a sticker with information on it. It should say something like CD-ROM, CD-RW or possibly DVD-R.

    Now, if you've had a chance to play around with the system, you may already know whether you can use OS 9 for internet, email, and so on. It might work just fine. However, the classic Mac OS is very old (in computer terms!) and is no longer supported, and you won't be able to use any modern programs, such as new versions of iTunes, etc. Moving to OS X will bring your computer into the modern world.

    If you can already use the internet on the iMacs, you will probably need to upgrade both your OS 9 software, and then, your iMac's firmware. This would allow you to run OS X.

    First, connect your iMac to the internet (feel free to jump in here if you're not sure how), and run the Software Update program to get up to 9.2.2.

    Then, follow the instructions carefully on this page to get that set up.

    The latest version of Mac OS X you can run is "OS X 10.4 Tiger". Athough Apple no longer sells it directly, you can get it from online retailers such as Amazon (shop around for price). Depending on what kind of drive you have, you'll need either the CDs or the DVD version.

    You will definitely have to upgrade your RAM, since you don't have enough to run Tiger. You have 128MB; your iMac will take 1GB. You should get two sticks of 512MB, which will be 168-pin SDRAM chips. I won't bombard you with too much information here, but again, you can shop around for this - Crucial.com has the right kind of memory, and is a very reliable store, but you may get better prices elsewhere.

    This is a indigo color slot load machine. m5521
    I checked the system profile and do not see the word firmware. there is a boot rom version that is 4.17f4 Is this it??
    Thanks so much

    Thanks Matt,
    I turned the machine over and it says CDRW.
    I will try to get on the internet using the ethernet. I bought a airport card and adapter and put it in, I think correctly but am unable to get it working.
    I will first update software to 9.2.2 (where would I find this?)
    Then would like to deal with the airport card issue so they can tie into my router.
    As form osx update, sounds good but is there a way to do this without upgrading memory? maybe something other than Tiger?

    Does this make sense?
    Thanks VW

    Hi VW

    Once the computer is attached to the internet, you should be able to use the built-in software update to get up to 9.2.2. Try attaching your ethernet cable, then see if you can get Internet Explorer to pick up a webpage. Software Update is found under your Apple menu. If that doesn't find the update, you can download them from here.

    Your firmware number (which is the Boot ROM you've found) indicates that you will eventually need to upgrade firmware to use OS X. I recommended Tiger because it was the latest you could use on that computer - 128MB is just enough to "officially" run 10.3 Panther, but it will run pretty slowly. I would strongly recommend you get some more memory - even going up to 512MB in total will stand you in good stead.

    Okay ... it's been a while since I looked at OS 9, but try this (with the ethernet cable connected).

    Under the Apple menu, go to Control Panel, then choose TCP/IP control panel.
    If you see "Connect via", choose Ethernet.
    If you see a "Configure" menu, choose "Using DHCP Server". Click OK or Apply if you see it.
    Hopefully that should give you an IP address. If you're plugged directly into the cable modem (and it isn't also a router), you'll see your public IP address appear in that TCP/IP panel. If you do, try Internet Explorer again. You might also try rebooting your modem and see if that forces an IP address.

    If you don't have any luck with that, I would recommend you post a question over on the OS 9 forum. There are lots of smart people there more familiar with OS 9 than I am!

    Hi,
    I tried the instructions to connect to the internet. There is no apply or okay button on the page. It still does not work. I checked with comcast, my ISP and they said it connecys with DHCP server. HELP
    Thank you

    Matt Clifton Level 7 Level 7 (27,790 points)
    At this point then, I would direct you over to the OS 9 forum. As I say, my 9 knowledge is a little rusty, but there are many people there who should be able to help you.

    Good luck!

    Richard,
    Thanks for this information. It was very helpful.
    I am a little further along with figuring this out.
    You mentioned that for web surfing with the upper grades you use at least 384 ram and 10.4.11
    What exactly is 10.4.11 is this Tiger ox or something else.
    thanks for your reply

    it is Tiger
    10.4 through 10.4.11

    -------


    There are some CD versions of tiger.
    http://store.fastmac.com/productinfo.php?productsid=111

    You could buy an external DVD drive. It needs to be firewire and bootable by Mac OS. If you have another PPC with firewire, you could try target Disk mode and installed tiger that way.

    You need to figure out the level of your firmware before installing 10.2 or greater. ( The PC name for firmware is BIOS. ) Installing 10.2 with a down level firmware will most likely make your iMac unusable and difficult to fix.

    Figuring out what level of firmware you have?
    1) Mac OS 9.x or 8.x, you need to use the Apple System Profiler.
    Apple -> Apple System Profiler

    2) Mac OS X, use the System Profiler.
    Apple -> About This Mac
    click on the More Info... tab
    click on Hardware
    read the Boot ROM Version

    3) Open Firmware, boot into Open Firmware.
    Power on your iMac while holding down commandoption+of
    The first output line contains the firmware level. Mine reads:
    Apple PowerMac4,1 4.1.9f1 BootRom built on 09/14/01 at 13.18.04
    Copyright 1994-2001 Apple Computer Inc.

    Some machine may not contain the firmware level but some other number which can be translated to the firmware level.

    On my machine, I have 4.1.9f1.

    What firmware do you need?
    http://docs.info.apple.com/article.html?artnum=86117

    For a slot loading iMac, this article indicates that you need to be running 9.1 or later.
    http://docs.info.apple.com/article.html?artnum=75130
    "The iMac Firmware Update 4.1.9 will only run on iMac computers with lot-loading CD or DVD drives running Mac OS 9.1 or later from a local drive. If you are using Mac OS X you must boot from a local Mac OS 9.1 or later writeable partition (not a CD, or network disk) prior to following the update instructions."

    You can download the Mac OS 9 updates from the Apple site.
    http://support.apple.com/kb/HT1387?viewlocale=en_US

    For tiger, you need 256meg of memory.


    There is no need to partition. You can save hard drive space by doing a custom install. Leave out the print drivers you do not need and the languages you do not need. Doing so you will need about three gigabytes of space.

    I tend to think dashboard is neat, but not neccesary for my everyday workflow.

    it is possible to enable and disable it as needed,
    by entering the following commands into the terminal:

    #To turn Dashboard off:
    defaults write com.apple.dashboard mcx-disabled -boolean YES

    #To turn Dashboard on:
    defaults write com.apple.dashboard mcx-disabled -boolean NO

    #*You have to restart the Dock after making either change for it to take effect:
    killall Dock

    Disable Spotlight, Bonjour and Dashboard:
