The Magnetic Drum Digital Differential Analyzer (MADDIDA) was a computer built by Northrop Aircraft Corporation in 1950.

MADDIDA had 44 integrators implemented using a magnetic drum with six storage tracks. The interconnections of the integrators were specified by writing an appropriate pattern of bits onto one of the tracks.
