That still would not have been practical for that environment (some of
which still exists today AFAIK).  Many of the clients were (are?) very
small credit unions and small banks.


While VM would have eliminated hardware it would not elminate the extra
maintenance and overhead of duplicate MVS images, monitors, system
software (scheduling, tape mgmt, etc.), CICS regions, application
libraries , JCL,  and duplicate batch processing.  The application
software was designed to run with multiple clients.
