The Motorola 680x0/m68k/68k/68K is a family of 32-bit CISC microprocessor CPU chips and was the primary competition for the Intel x86 family of chips in personal computers of the 1980s and early 1990s. Although no modern desktop computers are based on the 68k, derivative processors are still widely used in embedded applications. Source: Wikipedia (http://en.wikipedia.org/wiki/68k)

The Motorola 680x0 microprocessor series
The internal processor was 32-bit, but externally it used a 16-bit interface. It could address up to 16MB of RAM and execute three quarters of a MIPS (Million Instructions Per Second) on an 8MHz machine. The Amiga 1000, 2000 and 500 was clocked at 7.14MHz.
