The Motorola 68000 series (also known as 680x0, m68000, m68k, or 68k) is a family of 32-bit complex instruction set computer (CISC) microprocessors. During the 1980s and early 1990s, they were popular in personal computers and workstations and were the primary competitors of Intel 's x86 microprocessors.
An early advertisement for the Motorola's M6800 family microcomputer system The M6800 Microcomputer System (latter dubbed the Motorola 6800 family , M6800 family , or 68xx ) [ 1 ] [ 2 ] was a series of 8-bit microprocessors and microcontrollers from Motorola that began with the 6800 CPU .
The Motorola 68000 (sometimes shortened to Motorola 68k or m68k and usually pronounced "sixty-eight-thousand") [2] [3] is a 16/32-bit complex instruction set computer (CISC) microprocessor, introduced in 1979 by Motorola Semiconductor Products Sector. The design implements a 32-bit instruction set, with 32-bit registers and a 16-bit internal ...
Motorola agreed to complete the design and produce it on their PMOS lines in Phoenix. [11] While the design was eventually completed successfully, their fab proved unable to produce the chips. The problems with the line had become obvious with a number of similar failures; it also proved unable to make competitive memory devices and other designs.

68HC11 block diagram. Internally, the HC11 instruction set is backward compatible with the 6800 and features the addition of a Y index register. [a] It has two eight-bit accumulators, A and B, two sixteen-bit index registers, X and Y, a condition code register, a 16-bit stack pointer, and a program counter. In addition, there is an 8 x 8-bit ...
The Motorola 68040 ("sixty-eight-oh-forty") is a 32-bit microprocessor in the Motorola 68000 series, released in 1990. [2] It is the successor to the 68030 and is followed by the 68060, skipping the 68050. In keeping with general Motorola naming, the 68040 is often referred to as simply the '040 (pronounced oh-four-oh or oh-forty).
Motorola Single Board Computers is Motorola's production line of computer boards for embedded systems. [1] There are three different lines : mvme68k , mvmeppc and mvme88k . The first version of the board appeared in 1988.
