The Dimension 68000 wasn’t the only multiprocessor microcomputer, but it has taken on something of a legendary status. One of the first ads for the system placed in the December 1983 issue of BYTE drew more than 11,000 reader responses, the most for a single-page ad to that point. Techies were intrigued by the Dimension 68000’s capabilities. The original model could accommodate three processors in addition to its main Motorola 68000: Z80A, MOS Technology 6512, and Intel 8086. Each option could run CP/M, Apple II, and MS-DOS software, respectively in addition to the standard configuration’s Unix. Software to emulate Tandy/Radio Shack TRSDOS was also available. The company was sold to a group in Arkansas and reformed as Dimension Electronics in 1987. The system was relaunched as the New Dimension 68000 with an Apple Macintosh emulation option.
