Mouse Desk), a \"Finder\"-like GUI application for 8-bit Apples and clones with 128k of memory, utilizing double hi-res monochrome graphics (560x192), an optional mouse, and the ProDOS 8 operating system.\n\n💾 Download [Disk Images](https://github.com/a2stuff/a2d/releases)\n\n📖 Read the [Documentation](https://a2desktop.com/docs)\n\n📝 Check the [Release Notes](https://github.com/a2stuff/a2d/blob/main/RELEASE-NOTES.md)\n\n\n## Background\n\nThe application started its life as **Mouse Desk** by Version Soft. Apple Computer licensed the software and released it, at first as Mouse Desk 2.0, then rebranded **Apple II DeskTop** as the initial [system software for the Apple IIgs](http://www.whatisthe2gs.apple2.org.za/system-applications.html) before 16-bit GS/OS replaced it. It still functions on 8-bit Apples, including the Apple IIe, Apple IIc, Apple IIc Plus, Apple IIe Option Card for Macintosh, Laser 128, and Franklin ACE 2X00/500.\n\n* [History of Mouse Desk/Apple II DeskTop Versions](https://mirrors.apple2.org.za/ground.icaen.uiowa.edu/MiscInfo/Misc/mousedesk.info), by Jay Edwards\n* Overviews: [GUI Gallery](http://toastytech.com/guis/a2desk.html) \u0026mdash; [GUIdebook](https://guidebookgallery.org/guis/apple2/mousedesk)\n* Manual: [Apple IIgs System Disk User’s Guide (1986)](https://mirrors.apple2.org.za/ftp.apple.asimov.net/documentation/misc/Apple%20IIgs%20System%20Disk%20Users%20Guide%20%281986%29.pdf) - Chapter 2 “The DeskTop”\n* [Disk Images for Mouse Desk and Apple II DeskTop](https://mirrors.apple2.org.za/ftp.apple.asimov.net/images/masters/other_os/gui/)\n\nOther GUI environments exist for the 8-bit Apples, including [GEOS](http://toastytech.com/guis/a2geos.html) (which includes productivity applications) and [Quark Catalyst](http://toastytech.com/guis/qcat.html). While Apple II DeskTop is more limited then GEOS, serving only as a file manager and application launcher, it follows more common interface paradigms and is better integrated with ProDOS.\n\n## This Project\n\nThe goal of this project is to disassemble/reverse-engineer the suite with an eye towards understanding how it functions, fixing bugs, and adding functionality.\n\nSee the [Release Notes](RELEASE-NOTES.md) for a list of enhancements and fixes so far.\n\nEnd-user documentation is at the companion web site: https://a2desktop.com\n\n[![Alt Text](https://img.youtube.com/vi/zbElPj5zaBs/0.jpg)](https://www.youtube.com/watch?v=zbElPj5zaBs)\n\u003cbr\u003e\n_KansasFest 2018 presentation by @mgcaret_\n\nAdditional help is welcome!
