The division of labor among chips, as well as the CPU internals and slave processor protocol were designed early on. Thus the 08032 and 32032 are already available, differing only in external data paths. Compare this to Motorola, which first did a nice (but buggy) cpu, and deferred design attention to support chips. After an abortive attempt at an FPU, and a mediocre MMU, Motorola is promising a whiz-bang floating function processor "three months" after the 68020, due 4th quarter. And the 68020 suffers incompatability problems due to lack of foresight and planning. Finally, call a National tech sales office. They'll gladly sell you an MMU or FPU. My correspondent had used very early versions of these parts with a 6 MHz 16032, and they worked. Brendan Eich ...ihnp4!uiucdcs!uiuccsb!eich
