1-76. The principal internal storage in the Univac I system is the 1000-word acoustic delay-line memory, consisting of 100 10-word mercury registers. Twelve additional 10-word registers function as ... On a removable end-plate at the same end is a four-terminal barrier strip for the overheat and standby power lines.

The UNIVAC also employed mercury delay-line memories. Delay lines did not allow the computer to access immediately any item data held in its memory, but given the reliability problems of the alternative Cathode Ray Tube (CRT) technology, this was a good technical choice.

As well as complicating the architecture and programming of a computer using Mercury Acoustic Delay Lines, the mercury filled tubes were non standard components that had to be handled very carefully; they were bulky and had to be kept under close temperature control.

Some of the early computers stored data in mercury delay lines. These delay lines were constructed using a thin tube containing mercury and sealed with quartz (piezoelectric) crystals at each end. Applying an electric current to a quartz crystal causes it to vibrate.

Eckert’s idea was to use mercury delay lines (about which he already knew a great deal) for the memory. These delay lines were constructed using a thin tube containing mercury sealed with quartz crystals at each end.

In the late 1940s Dr. An Wang, and Jay Forrester, who was head of the Whirlwind computer project invented core memory at MIT. ... Magnetic core memory replaced vacuum tubes and mercury delay lines with a much more compact and reliable technology.
