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.
There is also no revision of the 68060, as Motorola was in the process of shifting away from the 68k and 88k processor lines into its new PowerPC business, so the 68070 was never developed.
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.
The Motorola 68000 is a CISC microprocessor, the first member of a successful family of microprocessors, which were all mostly software compatible.
Motorola ceased production of the 68000 in 2000, although derivatives, notably the CPU32 family, continue in production.
The Motorola 68901 had a number of severe defects, including the ability to lose the highest-priority interrupt if it and the clock interrupt happened within some window of each other.
Motorola released a series of motherboards for making "out of the box" systems based on the 88000, known as the MVME series, as well as the interesting Series 900 stackable computers.
All of these users were forced to move to other processors when Motorola later gave up on the m88k; DG went to Intel, Encore to the DEC Alpha.
There was also an attempt to popularize the system with the 88open group, similar to what Sun Microsystems was attempting with their SPARC design.
The 6800 is a microprocessor produced by Motorola and released shortly after the Intel 8080 in 1975.
The 6800 'fathered' several descendants, the pinnacle being the greatly extended and semi-compatible 6809, which was used in the Vectrex video game console and the TRS-80 Color Computer, among several others.
There are also many microcontrollers descended from the 6800 architecture, such as the Motorola 6801/6803, 6805, 68HC08, 68HC11 and 68HC12.

IBM approached Motorola with the goal of collaborating on the development of a family of single-chip microprocessors based on the POWER architecture.
At this point Motorola already had its own RISC design in the form of the 88000 which was doing poorly in the market.
This was a deliberate design goal on Motorola's part, who used the 603 project to build the basic core for all future generations of PPC chips.
Even though IBM engineers at the time wanted to use the Motorola 68000 in the PC, the company already had the rights to produce the 8086 line (by trading rights to Intel for its bubble memory) and it could use modified 8085-type components (and 68000-style components were much more scarce).
Motorola had already introduced the MC 68000, which had a 32-bit architecture internally, but a 16-bit pinout externally.
The Motorola 88000 design wasn't commercially available until 1990, and was cancelled soon after in favor of Motorola's deal with IBM and Apple to create the first PowerPC.
The Motorola 680x0, 0x0, m68k, or 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.
This family of chips built upon the 68h series of chips, which were their forebears.
The principal competitors in the microcomputer market for generation one were the P1 and P2 IA-16 chips (8088, 80286).
The Motorola '''680x0'''/'''0x0'''/'''m68k'''/'''68k'''/'''68K''' family of CISC microprocessor central processing unit chips were from the start, and were the primary competition for the Intel x86 family of chips.
the Motorola CPU32 (aka Motorola 68330), the MotorolaColdfire, and the MotorolaDragonball.
The principal competitors in the microcomputer market for generation one were the x86 architecture P1 and P2 chips (Pentiums), but to a lesser extent, as much of the hitherto 68k marketplace was shifting over to the PowerPC, sounding the death knell for the 680x0 on the desktop.
Each processing element (PE) contains one Motorola MC68000 (10 MHz) and 512 Kbytes of 150 nsec DRAM with DMA interface to a board level bus; a multiple processing element (MPE) board contains 8 PEs, a supervisory PE and an interface to a printed wire backplane; 16 MPEs fit in one card cage.
Card cages have eight parallel ports for communication with other card cages, or with external devices; they can be interconnected in a fractal network of arbitrary size; physical packaging in Krates of eight cages (1024 PEs; 512 Mbytes of memory).
