Spectre GCR
Encyclopedia
The Spectre GCR was a hardware add-on to the Atari
ST
computers that plugged into the cartridge port. Designed by David Small and sold through his company Gadgets by Small, it essentially turned the Atari ST into an Apple Macintosh computer. It was the final Macintosh emulator for the ST, and replaced the previous products Magic Sac and Spectre 128.
The Spectre GCR required the owner to purchase a set of official Apple Macintosh 128K ROMs and the Macintosh Operating System 6.0.8 disks. This avoided any legal issues of copying/pirating Apple's software. The emulator runs best with a high-resolution monochrome monitor, such as Atari's own SM124, but will run on colour displays by either displaying a user-selectable half of the Macintosh screen, or missing out alternate lines to fit the lower resolution colour display. The Spectre GCR plugged into the cartridge slot, and modified the frequency of the data to/from the single-speed floppy drive of the Atari ST, thus allowing it to read Macintosh GCR format discs which required a multi-speed floppy drive.
Although Spectre GCR would run in 1MB of memory, 2MB or more was recommended.
