I don't think it's really fair to call this "multi-tasking". Curtainly a predecessor, though. A more accurate description would be "task switching", whereby each application had reserved memory, but only one application ran at a time. At the user's request, another application would take over and run. There was no CPU time-slicing. That came later, when Apple introduced the Multifinder extension in System 7.
