4 unusual facts about Motorola 68000 family


Freescale ColdFire

The Freescale ColdFire is a microprocessor that derives from the Motorola 68000 family architecture, manufactured for embedded systems development by Freescale Semiconductor (formerly the semiconductor division of Motorola).

The instructions are only 16, 32, or 48 bits long, a simplification compared to the 68000 series.

Motorola 68030

The Motorola 68030 ("sixty-eight-oh-thirty") is a 32-bit microprocessor in Motorola's 68000 family.

OpenStep

NeXT's first operating system was NeXTSTEP, a sophisticated Mach-UNIX based operating system that originally ran only on NeXT's Motorola 68k-based workstations and that was then ported to run on 32-bit Intel x86-based "IBM-compatible" personal computers, PA-RISC-based workstations from Hewlett-Packard, and SPARC-based workstations from Sun Microsystems.


NaN

most processors (including those of the Intel/AMD x86-32/x86-64 family, the Motorola 68000 family, the AIM PowerPC family, the ARM family, and the Sun SPARC family) set the signaled/quiet bit to non-zero if the NaN is quiet, and to zero if the NaN is signaling.

Sony NEWS

It originally came equipped with a dual 680x0 (68020 or 68030) processor configuration running at 16-25 MHz, later shifting to the MIPS R3000 and R4000 RISC microprocessors.
