Macintosh ,released in 1984, had the 8-MHz found at the core of it. It
was also found in the Macintosh Plus, the original Macintosh SE, the Apple
Laser-Writer IISC, and the Hewlett-Packard's LaserJet printer family. The
68000 was very efficient for its time for example it could address 16 megabytes
of memory, that is 16 more times the memory than the Intel 8088 which was found
in the IBM PC. Also the 68000 has a linear addressing architecture which was
better than the 8088's segmented memory architecture because it made making
large applications more straightforward.

The 68020 was invented by Motorola in the mid-80's(Encarta 95). The 68020 is
about two times as powerful as the 68000. The 68020 has 32-bit addressing and a
32-bit data bus and is available in various speeds like 16MHz, 20MHz, 25MHz, and
33MHz. The microprocessor 68020 is found in the original Macintosh II and in the
LaserWriter IINT both of which are from Apple.

The 68030 microprocessor was invented by Motorola ...

any function that is math-based.
The microprocessor 68881 does this by additional set of instructions for high-
proformance floating point arithmetic, a set of floating-point data registers,
and 22 built-inconstants including p and powers of 10. The microprocessor 68881
conforms to the ANSI/IEEE 754-1985 standard for binary floating-point
arithmetic. When making the Macintosh II, Apple noticed that when they added a
68881, the improvement in performance of the interface, and thus the apparent
performance was changed dramatically. Apple then decided to add it as standard
equipment.

The microprocessor 80286, also called the 286was invented by Motorola in
1982(Encarta 95). The 286 was ...
