![]() rockets and missiles: Atlas, Redstone, etc. The early 68000-based Adobe PostScript interpreters and their hardware were named for Cold War-era U.S. Thereafter, Adobe generally preferred a RISC for its processor, as its competitors, with their PostScript clones, had already gone with RISCs, often an AMD 29000-series. A fast 68030 in later PostScript interpreters, including the standard resolution LaserWriter IIntx, IIf and IIg (also 300 dpi), the higher resolution LaserWriter Pro 600 series (usually 600 dpi, but limited to 300 dpi with minimum RAM installed) and the very high resolution Linotronic imagesetters, the 200PS (1500+ dpi) and 300PS (2500+ dpi). The 68000 in the Apple LaserWriter and LaserWriter Plus was clocked faster than the version used then in Macintosh computers. Many system specific ports of CP/M-68K were available, for example, TriSoft offered a port of the CP/M-68K for the Tandy Model 16/16B/6000.Īlso, and perhaps most significantly, the first several versions of Adobe's PostScript interpreters were 68000-based. There was a 68000 version of CP/M called CP/M-68K, which was initially proposed to be the Atari ST operating system, but Atari chose Atari TOS instead. The 680x0 were also the processors of choice in the 1980s for Unix workstations and servers such as AT&T's UNIX PC, Tandy's Model 16/16B/6000, Sun Microsystems' Sun-1, Sun-2, Sun-3, NeXT Computer, Silicon Graphics (SGI), and numerous others. However, the 680x0 CPU family became most well known as the processors powering advanced desktop computers and video game consoles such as the Apple Macintosh, the Commodore Amiga, the Sinclair QL, the Atari ST, the SNK NG AES/ Neo Geo CD, Atari Jaguar, Commodore CDTV, and several others. The 680x0 line of processors has been used in a variety of systems, from modern high-end Texas Instruments calculators (the TI-89, TI-92, and Voyage 200 lines) to all of the members of the Palm Pilot series that run Palm OS 1.x to 4.x (OS 5.x is ARM-based), and even radiation-hardened versions in the critical control systems of the Space Shuttle. The Sega Genesis used a 68000 clocked at 7.67 MHz as its main CPU.
