I was just curious about OS 9 that's all. I've been exploring and studying Apple technology lately and just wanted see what OS 9 was like.
Instead of trying to get OS 9 to load onto a modern CPU you might find it easier to go to EBay or a swap shop or even your town dump pick over area and grab an elder Macintosh.
If you really want to see and feel the experience of OS 9 complete with Chooser a nice Mac SE20 is the perfect box. That little screen is necessary to see how much good stuff was crammed into that operating system.
Come to think of it OS 9 won't run on a Mac SE20. You have to go with OS 7.55. You're not missing much using that instead of OS 9.
