That guide was for the 64-bit PowerPC CPU, which I think was only used in servers. For future reference, the iMac’s 32-bit processor needs the gcc-powerpc-linux-gnu package.

I want to preserve the MacOS 9 on the iMac, but I think I’ll do this on the 2005 Mac Mini.

Yeah its the most retro computer I have and I definitely want to have some fun with it!

I do have a 2005 Mac Mini with the PowerPC CPU, maybe it’ll work on that?

A great opportunity to learn Pascal, thanks!

Its really amazing how the Unix-like OSes can run on anything! I plan on keeping the original OS though, but thank you for the information.

Maybe I’ll make a game.

Thank you! I have spent some time learning Basic so Real Basic could be fun.

This is quite awesome! Unfortunately as far as servicing goes the machine has been sitting in our basement for years, no work has been done on it. I’m glad its still working, hopefully I can deal with the capacitors before its too late. It has its original hard drive which still works and has some cool old games on it and its running the original MacOS 9.

This is a great and direct guide, thank you!

Wow I had no clue it would be possible to develop on the machine itself! I’m glad people have maintained archives of this system’s software, it may be worth it to develop on the iMac itself, thank you!

Send it to me, I have plans.
