I hadn't quite put together how much desktop computing changed between 1994 (DOS, Windows 3.1, System 7) and 2001 (OS X, Windows XP), and how relatively little it's changed since then.
As someone born in 2001… yeah. Wow.
I don't think the PPC emulator ships with osx anymore.
Did the initial versions of osx recognize fat binaries or was that explicitly introduced later?
XNU has had support for fat binaries since NeXTSTEP.
