  PDA Encyclopedia - Motorola 68000
The Motorola 68000 is a CISC microprocessor, the first member of a successful family of microprocessors, which were all mostly software compatible.
In the Sega Saturn, the 68000 was used as the sound processor, and in the Atari Jaguar they were used as a main controller for all the other dedicated hardware IC's.
The 68000 was also unable to correctly return from an exception on a failing memory access, a crucial feature to enable true virtual memory.

 Motorola 68000 microprocessor family
Motorola 68000 is the first member of 680x0 line of microprocessors.
The 68000 architecture was much more flexible than other CPU familes (z80, 80x86, z80000, etc) as it could be very easily expanded to support full 32-bit data and address.
This 68000 microprocessor was not manufactured by Apple, but it was put into separate "Apple" category due to very unusual Apple copyright on the CPU.

 Motorola 68030
The 68030 is a 32-bit microprocessor in Motorola's 68000 family, with on-chip split instruction and data cache of 256 bytes each.
The 68030 was the successor to the Motorola 68020, and was followed by the Motorola 68040.
In keeping with general Motorola naming, this CPU is often referred to as the 030.

 Preface of The Motorola Microprocessor Family
The Motorola Microprocessor Family: 68000, 68008, 68010, 68020, 68030, and 68040
Because the Motorola family of microprocessors is quite diverse, this text initially concentrates on the 68000 and 68008 microprocessors.
The other family members, which include the 68010, 68020, 68030, and 68040, are compared and contrasted with the 68000 and 68008 in chapters 12 and 13.

 Motorola 68000
The Motorola 68000 is a CISC microprocessor, the first member of a successful family of microprocessors from Motorola, which were all mostly software compatible.
Initial samples of the 68000 were released in 1979, and competed against the Intel 8086 and Intel 80286 with some success.
The 68000 does provide a bus error exception which can be used to trap, but it does not save enough processor state to resume the faulted instruction once the operating system has handled the exception.

The successor to the Motorola 6809 and followed by the Motorola 68010.
The Zilog Z8000 and 68000 are similar in capabilities, but the 68000 is 32 bits internally, making it faster and eliminating forced segmentations.
The 68000 was used in many workstations, notably early Sun-2 machines, and personal computers, notably Apple Computer's first Macintoshes and the Amiga.

 68k - Wikipedia, the free encyclopedia
The Motorola 680x0/0x0/m68k/68k/68K family of CISC microprocessor CPU chips were 32-bit from the start, and were the primary competition for the Intel x86 family of chips.
Motorola mainly used even numbers for major revisions to the CPU core such as 68000, 68020, 68040 and 68060.
Had Motorola decided to stick with the 680x0 series, it is very likely that the next processor (68080) would have resembled Intel's P6 architecture.

 Motorola 68000 - Wikipedia, the free encyclopedia
As the first member of the successful m68k family of microprocessors, its software is generally forward compatible with the rest of the line.
Intel was next, with the Intel 8086/8088, but Motorola marketing stressed the (true) point that the 68000 was a much more complete 16-bit design than the others.
Additionally, the 68000 offered a "flat" 24-bit addressing system supporting up to 16 MB of memory; at the time, this was a very large memory space.

The competing Motorola 6800 architecture was cloned and improved in the MOS Technology 6502, rivaling the Z80 in popularity during the 1980s.
The 8080 is the ancestor of the 16-bit Intel 8086, the first member of the x86 family which powers most modern PC type computers.
Examples of other 16-bit microprocessor families include the Motorola 68000, used in early Apple Macintosh computers; and the Zilog Z8000.

 The PowerPC Initiative
That's why in October 1991, Apple, IBM, and Motorola joined forces to develop the new PowerPC architecture and a family of microprocessors, which they believe are the foundation for a new generation of personal computing.
Motorola now provides components that allow vendors to build PowerPC based systems using a single chip containing both memory and PCI bus controllers.
IBM and Motorola are working to make PowerPC the new standard in personal computing and the architecture on which the convergence of computing, telecommunications, and entertainment will ride.

The next breakthrough, in the late 1970s, was the development by Motorola and Intel of the microprocessors that became the heart of the Apple/Macintosh and IBM PC computers, respectively.
However, with the increasing power of the Intel and Motorola PC microprocessors, the computing world has tended to collapse towards personal computers and supercomputers, and even here the lines are blurred because many PCs can be networked together to form a virtual supercomputer.
WDC pioneered the licensing of microprocessor technology which was later followed by ARM and other microprocessor IP providers in the 1990’s.

A development of the Motorola 6800 by ex-Motorola engineers, the 6502 and its numerous variants powered many of the high-profile early micros, including the Commodore Pet, Apple II, and Commodore 64, not to mention the hordes of marginally compatible Apple clones.
The expensive Motorola 68000 was generally regarded as the best choice with its combination of simplicity and power.
Programmers loved the 68000 (no-one ever loved an 8088) and 68000 code tends to be small, fast and efficient.

When Apple moved from the Motorola 68000 family of processor to the PowerPC family of processors, they decided to emulate the older processors instructions.
The first PowerPC's were about as fast as the 68000 (68K) machines for running 68000 code (circa 1994 machines).
PPC's today can emulate a 68000 probably 10 times faster than any 68000 machine ever made.

Computers based on the Intel 80x86 family of processors store the least significant byte in the lower address and the most significant byte in the higher address.
Computers based on the Motorola 68000 family of processors, however, store integers in the opposite order.
In the example above, if an Intel machine transferred the integer value 16 in its native storage mode to a Motorola computer, which in turn interpreted the two bytes in its own native storage mode, the Motorola computer would think it had received the integer 100016, which is the decimal integer 4096.

 Small Dog Electronics - New and Refurbished Apple / Mac Computers
The popular Apple II line used NCR 6502 and 65C02 chips, and the Lisa and early Macintosh models took advantage of Motorola's 68000 series of processors.
After a decade of Macintosh computers based on Motorola's 68000 family of CPUs, Apple introduced the first Power Macintosh computers, or Power Macs, based on the next-generation PowerPC processors developed jointly by Motorola's RISC group (now the Freescale Semiconductor spinoff) and IBM Microelectronics.
Motorola also optimized these chips specifically for the Mac OS, and added a fast onboard "backside cache" (memory right in the chip) to substantially boost the chip's performance.
