Apple II Desktop Disassembly (AKA MouseDesk)

Joshua Bell, creator of the online version of the Applesoft and Logo interpreters and curator of, has a new project.  The project, with full sources on GitHub, is a complete disassembly of the program known as Apple II Desktop or MouseDesk by Version Soft.

According to the Apple II Desktop repository readme,

The goal of this project is to disassemble/reverse-engineer the suite with an eye towards understanding how it functions, and eventually fixing bugs and adding functionality.

While, Joshua has made sure to express that this work is definitely a “Work in Progress”, he has done a lot with it and has an eye towards actually rebuilding it and perhaps patching bugs eventually in the currently available versions.
