==Motorola== The [[Motorola 68000]] family had the [[Motorola 68881|68881/68882]] coprocessors which provided similar floating-point speed acceleration as for the Intel processors. Computers using the 68000 family but not equipped with the hardware floating-point processor could trap and emulate the floating-point instructions in software, which, although slower, allowed one binary version of the program to be distributed for both cases. The 68451 memory-management coprocessor was designed to work with the 68020 processor.<ref name=Ford92>William Ford, William R.
