Multitasking on the mac:
  Although possible the 68000 is too slow for context switching, to really
  make multitasking fast. Second DMA really doesn't exist on the mac
  thus the use of context switching when an I/O op is needed can't be
  done. Thus you would gain no speed up of overall programming in fact
  the overhead would make it miserably slow. With the 68020 and some
  intelligent scheme for I/o processes, multitasking could be worthwhile.
