DYSEAC was the second Standards Electronic Automatic Computer, a first-generation computer built by the United States National Bureau of Standards for the Army Signal Corps, going into operation in April 1954. Housed inside a truck, it was one of the first movable computers, using 900 vacuum tubes and 24,500 crystal diodes with 512 words of mercury delay-line memory, and it may have been the first computer to implement interrupts for input and output.

What could DYSEAC do with outside devices such as SEAC?
SEAC could interrupt DYSEAC and send it data without disrupting its computation.
DYSEAC had extensive abilities for real time interaction with outside devices. One of them was SEAC itself, which was able to interrupt computations on DYSEAC and send data into files on DYSEAC without disrupting the DYSEAC computation. The National Institute of Standards and Technology describes this as an early example of hardware based time sharing.
