Well, that's the beauty of open source. Go read it.

>When I look at this, it's so sophisticated it just makes me feel think about the widening divide as far as AI skill gap goes. Was AI used?
I feel like this was the "So tell me about your father.." turn here , did you really care about the details or did you want to wax poetic about AI?

Infinite Mac (https://infinitemac.org) is honestly incredible and gets you 99% of the way there for running old software for the nostalgia.
But there's definitely something fun about running the old hardware with an old spinning hard drive, clacking away while it boots up for 2-3 minutes.
And then launching Microsoft Word 5.1 and wondering if it locked up, while each toolbar loads in one by one!
Honestly though, if you just wanted to do word processing, it's fine for that, and with modern tools like FloppyEmu, BlueSCSI, and some of the networking hacks with modern cheap hardware, you can get one of these things to transfer files to and from a network share very easily.
I'm using a netatalk server on my Raspberry Pi to serve up Samba shares over AppleTalk. Very simple to do nowadays! https://github.com/geerlingguy/apple-pi
