A 68k personal rest on Motorola's 8/16-bit 68h series of processors.

The 68k family members

Generation one Motorola 68000 a hybrid 16/32 bit chip Motorola 68EC000 Motorola 68HC000 Motorola 68008 a hybrid 8/16/32 bit chip Motorola 68010 Motorola 68012 Generation ii (fully 32-bit) Motorola 68020 Motorola 68EC020 Motorola 68030 Motorola 68EC030 Generation iii (fully 32-bit) Motorola 68040 Motorola 68EC040 Motorola 68LC040 Generation 4 (fully 32-bit) Motorola 68060 Others Motorola CPU32 (aka Motorola 68330) Motorola Coldfire Motorola Dragonball

Architectural heritage

Humans world health organization come acquainted a PDP-11 or VAX usually feel comfortable sustaining a 68000. Sustaining the exception of a split of general purpose registers into specialised information & location registers, the 68000 architecture is around several ways a 32-bit PDP-11.

Where did the 68050 go? Was there no -070?

Note that no 68050, this is because a project that was destined to exist as the 68050 was in time freed as a version of the 68040. There exists likewise there is no revision of the 68060, as Motorola was in a run of shifting out of the 68k & 88k processor lines into its new PowerPC business, so a 68070 was never developed. Experienced it been, it would keep around been the revised 68060.

The next 68k generation

A Quaternary generation 68060 shared most of the features of the Intel P5 architecture of x86. Should Motorola own decided to stick by owning a 680x0 series these are very likely that a next processor (68080) would have resembled Intel's P6 architecture.

Other variants

When a mainline 68k processors' death, a 68k personal has been utilized to occasionally extent within microcontroller/embedded microprocessor versions. These chips include a ones enrolled under "other" above, i personally.e. a CPU32 (aka 68330), the Coldfire, and a Dragonball.

Competitors to the mainstream 68ks

A chief contender in the microcomputer market for generation one were a x86 architecture P1 and P2 IA-16 chips (8088, 80286). For generation 2, it was a P3 IA-32 chips (80386), and for generation ternary it was a P4 IA-32 chips (80486). Generation quaternion did compete against a P5 IA-32 chips (Pentiums), but less, as much of the yet 68k marketplace was shifting assibilate to the PowerPC, sounding the demise knell for the 680x0 on the desktop.
