The 1102 was a variant of the UNIVAC 1101, using its 24-bit word and a smaller (only 8192 words) drum memory. The machine had 2700 vacuum tubes, weighed 14,000 pounds, and occupied 122 square feet of floor area.
The computers were connected to data channels coming from the wind tunnels and the engine facility. There were five typewriters for printed output, five paper tape punches, and four pen plotters to produce graphs.
The three computers and related peripherals were delivered between July 1954 and March 1956 at a total price of $1,400,000. Software for the computers was developed entirely at the Arnold Engineering Development center. All programing was done in machine language (assemblers and compilers were never developed).
