Same here. There are really just a few small programs I'd need to be happy using System 7 (tarted up with a bunch of extensions) on a modern computer. It just goes to show that an excellent OS design is never really outdated (which is why Windows 8 was such a flop, tried to fix what wasn't broken)

If Apple would open source System 7, I'd be thrilled. I'd rally a community of developers to bring it up to speed with modern conventions and go from there. I have no doubt ti would be popular with the minimalist community, considering I can get a fully functional System 7 to run in just 3 MB of memory as-is. I can see something like System 7 being awesome on a Raspberry PI.
