Re: Can OS X run on G3 iMac??

Hey there, I was just wondering if anyone has any experience running OS X on any machines as old as a 1st Gen iMac 233 with 96 MB RAM. Here is the situation... I'm heading off to Madison in month for my first year of college and I'm waiting for the 15" Powerbook update (along with everyone else under the sun). But I have lost all faith that Apple will come through in time. So I am planning on taking my family's old iMac for the first month (hopefully less) of school and I'd really really like to be running OS X. I have a friend with the OS but it will take some time to get ahold of and it will take some time to install everything, so I was just wondering if anyone knows if the whole process is worth it. Thanks for the input!
A G3 233 iMac can work with Mac OS X providing you:
1. Upgrade to at least 160 MB of RAM.
2. Get the Sonnet Upgrade card or better which provides Firewire and a faster processor. Only compatible with the 233 and 266 G3 iMac. The 333 through 400 Mhz iMacs without Firewire port and pre-iBook SE without Firewire port iBooks are not worth getting for Mac OS X.
3. Don't use it for running Mac OS 9 applications.
4. Upgrade the firmware before upgrading the operating system.
5. Install with at least 2.5 GB of hard disk space free (that may mean getting a technician to install an 8GB or bigger hard drive depending on how much data you want on it).
6. If you do get a hard drive bigger than 8 GB, you should make sure to format it so that the first 7.95 GB are used to install the Mac OS X operating system. Disk Utility that comes on the Mac OS X installer CD allows you to partition the drive (which erases it clean). This is a limitation of all 333 Mhz and slower Macs.
7. Don't install anything less than Mac OS X 10.2.
Mac OS X's biggest Achilles' heel is having to run old Mac OS 9 applications at the same time as X while using the Classic environment or allowing you to boot directly into 9. Each time you do that, applications may ruin X's permissions, and you have to go to the Hard Drive's Applications -> Utilities -> Disk Utility -> First Aid tab -> Select hard disk -> Hit repair permissions each time you think permissions might have gotten corrupted. Running Classic also limits Mac OS 9 applications to 128 MB of RAM. You can still boot into 9, thanks to Apple menu -> System Preferences -> Classic in Mac OS X, but when you do, you have to be especially careful not to touch essential documents that are only visible when you boot into Mac OS 9, and essential folders for Mac OS X.

If you want, you probably can get an iMac DV for as little as $500 from one of these
