factoids

Executor is a software application that allows Motorola 68000-based classic Mac OS programs to be run on various x86-based operating systems. Executor was created by ARDI (Abacus Research and Development, Inc.). As of 2005, Executor development has been indefinitely postponed. As of 2008, it was published as open source software.WEB, ARDI website,weblink February 24, 2009, dead,weblink" title="web.archive.org/web/20090401132132weblink">weblink April 1, 2009,

Overview

Executor was originally developed to run Mac programs on the NextStep platform.Dan Lavin, "Macintosh emulation nears", Nextworld EXTRA, September 1991 and other MC680x0-based Unix systems like SunStation."Cloning The Mac", Macworld, January 1992, page 107 During that time, two other similar products also existed for Unix systems: Liken from Xcelerated Systems Inc, and Equal from Quorum Inc."Mac Software Invades Alien Computer", Macworld, July 1993, page 87Unlike true Macintosh emulators, Executor requires no startup ROM images or other Apple intellectual property.WEB, Setting up Executor For Windows,weblink E-Maculation, August 30, 2010, January 2009, Executor, much like Wine for running Windows applications on Unix-like platforms, translates Macintosh Toolbox API calls and QuickDraw routines into equivalent Win32 or POSIX API calls. The MS-DOS version of Executor runs using the CWSDPMI protected mode DOS extender.Executor translates 68k big-endian binary code into x86 little-endian binary code.NEWS, Emulate Mac OS on your Linux box,weblink Cable News Network, CNN.com, February 24, 2009, Pawel, Leszek, May 4, 2000, Executor can only run Macintosh programs designed to run on 68000-based Macintosh hardware. Executor can mimic either Macintosh System 7.0.0, or System 6.0.7 for older applications that are incompatible with System 7.0.0.Due to the GUI-oriented nature of classic Mac OS applications, Executor has its own GUI environment known as Browser. It mimics the classic Mac OS desktop and the Finder application without having features such as the trash can or Control Panels. The default Apple menu also does not exist in Browser but is replaced with a rough equivalent; running Mac applications will have Apple menu functions available. Executor does not have support for networking of any type, including AppleTalk support. Executor also lacks the ability to run components (such as extensions or control panels) that are highly integrated with classic Mac OS versions. Due to the differences between the actual MacOS ROM and the emulation provided by Executor, other compatibility issues exist.WEB, Open source ROM replacement? in Mini vMac FAQ,weblink August 30, 2010, For example, heise Magazine reported issues with installation of many programs, and running early versions of StarWriter and Adobe PageMill. However, once installed, Microsoft Word, Excel and BBEdit Lite are usable.WEB, Executor - using Mac applications under Linux (The Executor), Heinz Heise, heise Magazine,weblink Stefan, Kühnel, August 30, 2010, However, the Unofficial Macintosh Emulation Pages reports successfully running Executor with 24MB of RAM on Windows 95.WEB, Executor/DOS under Win32, Unofficial Macintosh Emulation Pages,weblink August 30, 2010, After considering an open source release of the source code for some time, Matthews released the source code for the executor and syn68k applications on October 5, 2008, under a very permissive MIT-style license.
