M680 generally refers to the Motorola 68000 series microprocessors, a family of 16/32-bit CISC microprocessors introduced in the late 1970s. These CPUs were widely used in computers, embedded systems, and workstations due to their powerful instruction set, efficient addressing modes, and relatively straightforward architecture. The M68000 series became popular in early personal computers like the Apple Macintosh, Commodore Amiga, and Atari ST.
Key features of the M68000 include:
-
16-bit external data bus with a 32-bit internal architecture
-
24-bit addressing capable of addressing up to 16 MB of memory
-
Rich instruction set with efficient support for complex operations
-
Designed for easy programming and efficient multitasking
