I am running the lastest OSX on a beige G3 ex-266 desktop box. If you missed the description of the upgrades that I posted, I can email them to you. Here's some comments on your message: * You should increase the RAM to at least 512; I have 3x256. OSX works better with a lot of RAM, especially running Classic. At least you don't need odd low profile sticks like I did. * There is a chance that the USB PCI card will not work, but the one I bought did. * The is something called a MESH bug in the beige G3s that causes SCSI to not work with OSX. (I reboot into OS 9 to use my SCSI scanner and external drive.) * For this reason, you will have to install OSX on your internal drive. * OSX does not support the floppy drive in a G3. Use OS9 for that. * The version of OS9 that was made to work best with OSX is 9.2.2. I suppose 9.1 will work OK. * On a beige G3 with a partitioned drive, OSX must be installed on the first partition, which must be 8 GB or smaller and formatted in HSF+. * When installing OSX, you need to have an OS9 for OSX to use for Classic. I told it not to install its own OS 9.2.2 on the OSX partition, because that OS9 would have none of my third party extensions. For Classic, I told the Installer to use my OS 9.2.2 which was on its own partition, already loaded with years of extensions. * In your case, you are going to need to let the Installer install its OS9 on your OSX partition, because it OSX won't be able to see your OS 9.1 on the SCSI drive. * Or, maybe you can shuffle your partitons as described in my upgrade message. Buy a new 80 GB drive, plug it in to your CD's cables, format and partition it, make the first partition under 8 GB for OSX, copy your whole SCSI drive to the second partition. Copy the rest of your old 80 GB drive to whatever other partitions you have made. Test boot off the OS9 second partition, then install the new drive in place of the old drive and reconnect the CD. Then you are ready to install OSX on the first partition and tell it to use your OS 9.1 for Classic. * When running either OSX or OS9, I can see all my partitions mounted, and can see all the files in any partition. * I keep all my docs in a Data partition. When an OS9 document is clicked while running OSX, my OS9 is launched as Classic and the OS9 application opens the document. * It all works perfectly. And OSX never crashes.
