  On the programming side, there wasn't either the
memory capacity or
 processing power to implement a modern disk file system.  One of the
 first computers I worked with was a System/360 model 25 running
 DOS/360.  The machine had 48K of core memory, 12K of which was for the
 OS, leaving 36K for programs.  No virtual memory. 
Unix was a counterexample. Recall that v1 worked on a 24K
machine, 16K of which was OS and 8K user. And it had a modern
file system. Programming was so much easier that it lured
people (e.g. me) away from big mainframe computers.
