Mac OS 7, Yes 7, On An iPhone
More humorous than practical, the folks at ‘MacOS iPhone Project’ have managed to load an iPhone with Mac OS 7. Yes, 7, from like the 1990s. Apparently it uses QEMU, which is some sort of emulator that was also used to load a Nokia N95 with Windows 3.1. Ahh, sweet flashback. More pics below.
