Eumel grew into a complete multi-tasking, multi-user operating system supporting orthogonal persistence, which started shipping in 1980 and was later ported to Zilog Z8000, Motorola 68000 and Intel 8086 processors.

As the original 68000 processor in Amigas tended only to access memory on every second available memory cycle, Agnus operated a system where the time-critical custom chips access got the " odd " clock cycle and the CPU got the " even " cycle, thus the CPU did not generally get locked out of memory access and did not appear to slow down.

The 68010 was never as popular as the 68000, as the added complexity and cost turned out not to be worthwhile in practice.

These relatively large buses made it hard to design a low-cost system around the 68000 ; they were difficult to lay out on a circuit board and needed a lot of supporting circuitry.

MacsBug is an acronym for Motorola Advanced Computer Systems Debugger, as opposed to Macintosh debugger ( The Motorola 68000 Microprocessor is imprinted with the MACSS acronym ).

Based on the Motorola 68000 family of microprocessors, the machine sports a custom chipset with graphics and sound capabilities that were unprecedented for the price, and a pre-emptive multitasking operating system called AmigaOS.

The Motorola 68000 series of microprocessors was used in all Amiga models from Commodore.

Early CPU accelerator cards feature full 32-bit CPUs of the 68000 family such as the Motorola 68020 and Motorola 68030, almost always with 32-bit memory and usually with FPUs and MMUs or the facility to add them.

The Atari ST was part of the 16 / 32 bit generation of home computers, based on the Motorola 68000 CPU noted for 128 kB of RAM or more, a graphical user interface, and 3½ " microfloppy disks as storage.

A PDP-10, a PDP-8, an Intel 386, an Intel 4004, a Motorola 68000, a System z mainframe, a Burroughs B5000, a VAX, a Zilog Z80000, and a 6502 all vary wildly in the number, sizes, and formats of instructions, the number, types, and sizes of registers, and the available data types.

Motorola / Freescale Semiconductor's DragonBall, or MC68328, is a microcontroller design based on the famous 68000 core, but implemented as an all-in-one low-power solution for handheld computer use.

The first field is either the Motorola 68000 exception number that occurred ( if a CPU error occurs ) or an internal error identifier ( such as an ' Out of Memory ' code ), in case of a system software error.

GDB target processors ( as of 2003 ) include: Alpha, ARM, AVR, H8 / 300, System / 370, System 390, X86 and its 64-bit extension X86-64, IA-64 " Itanium ", Motorola 68000, MIPS, PA-RISC, PowerPC, SuperH, SPARC, and VAX.

Some of IBM's engineers and other employees wanted to use the IBM 801 processor, some would prefer the new Motorola 68000, while others argued for a small and simple microprocessor, such as the MOS Technology 6502 or Zilog Z80, which had been used in earlier personal computers.

MINIX 1. 5, released in 1991, included support for MicroChannel IBM PS / 2 systems and was also ported to the Motorola 68000 and SPARC architectures, supporting the Atari ST, Commodore Amiga, Apple Macintosh and Sun SPARCstation computer platforms.

The Motorola 68000 is a 16 / 32-bit CISC microprocessor core designed and marketed by Freescale Semiconductor ( formerly Motorola Semiconductor Products Sector ).

Tom Gunter, retired Corporate Vice President at Motorola, is known as the " Father of the 68000.

* Versions of OS-9 / 68K ran on a wide variety of 68000 family platforms, including the Sharp X68000 in Japan, some personal computers intended by their designers as upgrades from the Color Computer ( e. g., the 68070 and 68340-based MM / 1, and on other computers from Frank Hogg Laboratories, PEP Modular Computers, and Delmar Co .) It was also ported to the Atari ST by Recc-o-ware in the early 1990s, and was distributed by Cumana in Europe.

The Acorn Business Computer ( ABC ) plan required a number of second processors to be made to work with the BBC Micro platform, but processors such as the Motorola 68000 and National Semiconductor 32016 were unsuitable, and the 6502 was not powerful enough for a graphics based user interface.

In the early 1980s, with the advent of 32-bit microprocessors such as the Motorola 68000, a number of new participants in this field appeared, including Apollo Computer and Sun Microsystems, who created Unix-based workstations based on this processor.

TRIPOS was ported to a number of machines, including the Data General Nova 2, the Computer Automation LSI4, Motorola 68000 and Intel 8086-based hardware.

The Intel x86 microprocessors would go on to become the brains for the IBM PC, while the Motorola 68000 would become the heart of the Apple Computer line.

Since Apple Computer never manufactured a 68060-based Mac, the fastest way to run native 68000 Mac OS applications without emulation is to run it on an Atari or Amiga with a 68060 upgrade.

A modified version of the 68000 formed the basis of the IBM XT / 370 Hardware emulator of a System 370 processor.

SGI's first generation products, starting with the IRIS 1000 ( Integrated Raster Imaging System ) series of high-performance graphics terminals, were based on the Motorola 68000 family of microprocessors.

For example, TeleSoft ( also located in San Diego ) offered an early Ada development environment that used p-code and was therefore able to run on a number of hardware platforms including the Motorola 68000, the System / 370, and the Pascal MicroEngine.

Alpha Microsystems originally planned to migrate to the 88K architecture from the Motorola 68000, and internally created a machine around it running UNIX System V, but it was later scrapped in favour of later 68K derivatives.

Programming languages available at the time included MacBASIC, MacPascal, and the Macintosh 68000 Development System.

vMac and Mini vMac emulate a Macintosh Plus and can run Apple Macintosh System versions 1. 1 to 7. 5. 5. vMac and Mini vMac support central processing unit ( CPU ) emulation from Motorola 68000 to 68040, display output, sound, floppy disk insert, HFV image files, and more.

Although Idris was initially available for the PDP-11, it later ported to run on a number of platforms, such as the VAX, Motorola 68000, System / 370 and Intel 8086.

Working independently under the Bloodlust Software banner, Addis wrote NESticle, Genecyst and Callus ( and also a QSound player ), emulators of the Nintendo Entertainment System, Sega Genesis and CP System respectively, writing his own code for the MOS Technology 6502, Motorola 68000 and Zilog Z80.

ARDI reverse engineered the Mac ROM and built a 68000 CPU emulator, enabling Executor to run most ( but not all ) Macintosh software, from System 5 to System 7, with good speed.
