The Manual Data Keyboard (MDK), manufactured by IBM, consists of a ten-digit keypad. Together with the Manual Data Readout device, it was used to input numbers into the Gemini spacecraft on-board computer. Numbers entered via this unit would select memory addresses in the computer, as well as enter actual numerical data. What the numbers signified was determined by settings on the MDR.

This keyboard was taken from the Gemini 7 spacecraft, which flew in Earth orbit in December 1965, piloted by astronauts Frank Borman and James Lovell, Jr. NASA transferred this MDK to the Museum in 1976.
