Wikipedia lists 18 UNIVACs shipped by 1954 so that's certainly low.
With the 702, the ERA machines and the one-offs like JOHNNIAC I'd
guess the number was more like 50, but soon increased with multiple
IBM 704 and 650 machines starting in 1954.

The 650s at leat ran all night. Alan Perlis told me some amusing
stories of tripping in the dark over sleeping grad student wives who
were holding their husbands' place in line for the 650 in the middle
of the night. They soon made the scheduling more humane.
