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 68008 microprocessor family
Motorola 68008 (MC68008) microprocessor belongs to the first generation of 68000 microprocessors.
The 68008 is fully object-code compatible with the 68000, but not pin-compatible with it.
Due to smaller size of the data bus the Motorola 68008 needs twice as many fetches to read instructions and data - this makes the CPU slower than the 68000 microprocessor running at the same frequency.

 68k - Encyclopedia, History, Geography and Biography
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.

 Motorola 68000 microprocessor family
Motorola 68000 (MC68000) is the first member of 680x0 line of microprocessors.
Motorola also made 68008 - a version of 68000 CPU with 8-bit external data bus.
The 68000 architecture was much more flexible than other CPU families (z80, 80x86, z80000, etc) from programming point of view as it could be easily expanded to support full 32-bit data and address buses.

Motorola 68020 (MC68020) is a 32-bit microprocessor compatible with earlier members of 680x0 family - 68000, 68008 and 68010.
Address bus width on the 68020 is increased to 32 bits, which allows the processor to address up to 4 GB of memory.
These processors were custom made by Motorola for other companies, therefore all of them were marked with custom part numbers.

 Definition of Motorola 68008
The Motorola MC68008 is a 8/16/32-bit microprocessor from the early 1980s.
It is an 8-bit bus version of the Motorola MC68000, and can address 1MB or 4MB of memory (using a 48-pin or 52-pin package, respectively).
The original 48-pin package version was used in the Sinclair QL, to make maximum use of inexpensive 8-bit technology on the motherboard while computing internally with the relatively fast 16/32-bit processing engine.

Introduced in 1979 it was actually a 32 bit architecture internally, but had a 16 bit data bus and 24 bit address bus to fit in a 64 pin package.
Variants of the 68000 include the 68HC000 (a low-power HCMOS implementation, 0.13-0.26 W compared to 1.2 W NMOS) and the 68EC000 with selectable 8 or 16 bit data bus.

 [No title]
The microprocessor chosen was the Motorola 68008, which, using a software program written in 68000 assembly language, controlled the acquirement of ECG data samples, the storing of these samples and the output of them at a much higher frequency than that at which they were sampled.
The Motorola 68008 microprocessor was chosen for the project development, the reason being that this was the processor that I had studied in the second year of my course and thus I was familiar with it.
A 20 pin header was used to enable the 68008 to be placed in free-run mode by shorting the data bus to ground and floating DTACK high.

 A Small MC68008 Computer System
Specifically, the only major differences are that the Motorola board has a cassette interface, more spare I/O lines, and a small wirewrap expansion area, whereas the system described here has somewhat better performance, using an 8 MHz MC68008 rather than the 4 MHz MC68000 used in the Motorola system.
The difference in complexity between the Motorola board and the design presented here is primarily due to the fact that this design uses several parts not available when the Motorola board was designed, and requires less circuitry due to its use of an eight bit data bus.
With a monitor program similar in function to that provided with the Motorola board, this design could equally well be used in an educational context, at a potential savings in cost.

 Comments on 7211 | Ask MetaFilter
Your choice of the 68008, I assume, is being made in order to simplify the design of the product.
The 68K8 was Motorola's attempt at making a chip with the power of a 68K but with a slightly simplified addressing scheme (8 bit data bus).
The problem with this is that the chip is really a 16/32 bit data bus chip, which means that in order to fetch a long word, it has to hit the data bus 4 times.
