indeed.    There were exceptions, but yes, this involved 'additional 
hardware assistance' in the form of bank switching, or bank mapping.    
Altos Computers and others made Z80 systems which had 4 or more banks of 
64K memory minus a small chunk of shared memory, these ran the multiuser 
CP/M known as MP/M-80... IIRC, this was circa 1979 or 1980.
