# A2D
|
|
|
|
Work-in-Progress disassembly of Apple II Desktop (a.k.a. A2.Desktop)
|
|
|
|
## Background
|
|
|
|
A2.Desktop started its life as "Mousedesk" by Version Soft, as a mouse-driven
|
|
Mac-like "Finder" GUI application for 8-bit Apples with 128k of memory
|
|
(Enhanced Apple //e, Apple //c) using double-hires monochrome graphics
|
|
(560x192) and the ProDOS operating system.
|
|
|
|
Although the history is sketchy, it appears that Apple Computer licensed
|
|
(or acquired) the software, and released it - rebranded as Apple II Desktop -
|
|
as the initial system software for the Apple IIgs before 16-bit GS/OS
|
|
replaced it. The rebranded version still functions on 8-bit Apples.

|
|
|
|
Other GUI environments exist for the 8-bit Apples, including GEOS (which includes
|
|
productivity applications) and Quark Catalyst. While A2.Desktop is more limited -
|
|
serving only as a file manager and application launcher - it is (subjectively)
|
|
more visually appealing and better integrated with ProDOS.
|
|
|
|
## Goal
|
|
|
|
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.
|
|
|
|
## Tools
|
|
|
|
The [cc65](http://cc65.github.io/cc65/) tool chain will be used; source files will
|
|
target the ca65 macro assembler. Cross-development on modern systems will be assumed.
|
|
(Sorry, Merlin purists! We still love you.)

## Code of Conduct
|
|
|
|
Discussions should be polite, respectful and inclusive, and focus on the code.
|
|
Harassment will not be tolerated. Keep comments constructive.
