Apple II DeskTop Turns a II Into a Mac

Apple II DeskTop (also known as MouseDesk) is a remarkable piece of software developed for the Apple IIe and //c way back in 1985. It replicated the look and feel of a Mac desktop on the II with surprisingly decent performance.

It is still being worked on and is now open source. It works on original hardware as well as emulators (including the MiSTer).
