Motorola 68000
The Motorola 68000 (sometimes shortened to Motorola 68k or m68k and usually pronounced "sixty-eight-thousand") is a 16/32-bit complex instruction set computer (CISC) microprocessor, introduced in 1979 by Motorola Semiconductor Products Sector ...
development system called the ''
EXORmacs'' which featured the
VERSAbus and an array of option cards. They were typically connected to CDC Phoenix disk drives running one to four 14-inch platters. The EXORmacs was used to emulate a 680xx processor
in-circuit, speeding development of 680xx based systems. It also hosted several compilers and assemblers.
VERSAdos and the EXORmacs were produced by
