The 68000 is a 16/32-bit microprocessor designed by Motorola and introduced in 1979. It was widely used in personal computers, workstations, and embedded systems due to its powerful architecture and ease of programming. The processor features a 32-bit data bus and a 24-bit address bus, allowing it to access up to 16 megabytes of memory. The 68000 architecture includes a rich set of instructions and a flexible addressing mode, making it suitable for various applications. It served as the foundation for several popular systems, including the Apple Macintosh, Atari ST, and Commodore Amiga, influencing the development of future microprocessors.
