I just bought my first Mac (yes, it is sad) to see what it was all about. I am in the process of bringing RAM up to 256mb, and wonder if I can run Panther on it? Currently has OS 9.1 installed.
I have updated the firmware already.
We need to know what kind of mac you have exactly. Your title indicates its an iMac, and Panther is supported on all model iMacs ever made. If this is an old tray loader, you need to install firmware update 1.2 first. If its a tray loader with an upgraded hard drive, it has to be partitioned so OS X resides entirely within the first 8 gigs of the drive.
If its a slot loader, you MUST install firmware update 4.1.9 first.
If its a G4 or better, I don't know of any issues to contend with.
