The CTSS approach is primitive compared to present-day time sharing, but
it was effective. It was extremely simple, which minimized the size of the monitor.
Because a job was always loaded into the same locations in memory, there was no
need for relocation techniques at load time (discussed subsequently). The technique
of only writing out what was necessary minimized disk activity. Running on the
7094, CTSS supported a maximum of 32 users.
