Hey people of Macintosh Garden! I came here because I got an old iMac G3 with Mac OS 9.2.2 installed. It really got boring after fooling around the settings and stuff so I came here for... some things. (I think I got away with that.)
I have verified that the version of 10.0.3 I have added/replaced on my external download list works. Should download as "MacOS_10_0_3.toast.sit".
