update or patch is installed). This was possible because WordPerfect for the Atari ST was designed from the ground up and was optimized for the Motorola 68000 processor as well as Atari's GEM (Graphics Environment Manager) operating system. WordPerfect for the Atari ST retailed at US$395 with a student version for US$99. The price of WordPerfect was significantly higher than most of the other Atari word processors available at the time. Atari Corporation published a version of Microsoft Write (the Atari version of Microsoft Word 1.05 for the Macintosh) for US$129.95 (almost 75% off the suggested retail price of WordPerfect), which did not help WordPerfect's campaign to establish itself as the standard word processor on the Atari platform. Like other versions, WordPerfect for the ST was not copy-protected. In 1988 WordPerfect threatened to abandon the Atari market after copies of the word processor were found on several pirate bulletin board systems. However, support from the Atari community convinced WordPerfect to reconsider and support for the Atari ST continued, but only a single developer was assigned to the project to fix bugs. A WordPerfect 5.1 version for the Atari ST was planned and in development but was later cancelled. Amiga In 1987, WordPerfect was ported to the Amiga 1000 and was upgraded through version 4.1 on the Amiga platform despite rumors of its discontinuation. The company's efforts were not well supported by Amiga users and it did not sell well. Though it could be started from the Workbench or CLI, WordPerfect remained a fundamentally text-oriented program and retained its DOS command structure. Satellite Software received criticism for releasing a non-graphical word processor on a graphically oriented system. In 1989, WordPerfect Corporation stopped all Amiga development, including work on a version of PlanPerfect, stating that it had lost $800,000 on the computer and could not afford to add Amiga-specific features. After customers stated that they would be satisfied with a DOS-like word processor the company resumed development of only the Amiga version of WordPerfect, but discontinued it in 1992. Linux In 1995, WordPerfect 6.0 was made available for Linux as part of Caldera's internet office package. In late 1997, a newer version was made available for download, but had to be purchased to be activated. In 1998 Corel released WordPerfect 8.0 for Linux. The full version was sold as a package. A cut-down version was made available for downloading. Hoping to establish
