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.

	Mac 68K emulator - Wikipedia, the free encyclopedia (458 words) This emulator permitted the running of applications and system code that were originally written for the 680x0 based Macintosh models. This worked by "recompiling" common sections of 680x0 code into faster sequences that were locally cached. For 680x0 code, a UPP was an ordinary pointer, so already-compiled code did not need to be changed to run. 680x0 - definition of 680x0 in Encyclopedia (319 words) 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. Should Motorola have decided to stick with the 680x0 series it is very likely that the next processor (68080) would have resembled Intel's P6 architecture. Generation four did compete against the P5 IA-32 chips (Pentiums), but to a lesser extent, as much of the marketplace was shifting over to the PowerPC, sounding the death knell for the 680x0 on the desktop.
