used in the Sun Microsystems Sun-3 workstations, IBM RT PC workstations, Apple Computer Macintosh II family, NeXT Computer, Sharp X68000, Amiga 3000, Convergent Technologies MightyFrame, Atari Mega STE, TT, and Falcon. Some third-party Amiga and Atari products used the 68881 or 68882 as a memory-mapped peripheral to the 68000. Versions 68881 155 000 transistors on-chip 12 MHz version 16 MHz version ran at 160 kFLOPS 20 MHz version ran at 192 kFLOPS 25 MHz version ran at 240 kFLOPS 68882 176 000 transistors on-chip 25 MHz version ran at 264 kFLOPS 33 MHz version ran at 352 kFLOPS 40 MHz version ran at 422 kFLOPS 50 MHz version ran at 528 kFLOPS These statistics came from the comp.sys.m68k FAQ. No statistics are listed for the 16 MHz and 20 MHz 68882, though these chips were indeed produced. Legacy Starting with the Motorola 68040, floating point support was included in the CPU itself.
