 Both ILLIAC and MISTIC were based on the Institute for Advanced Study's (IAS) computer, known for its revolutionary storage of data and instructions in the same memory.MISTIC and IAS consisted of five sections—input, memory, arithmetic processing, control, and output—setting the standard for at least twelve other computers later built.MISTIC was built on the fifth floor, Room 500, of the Electrical Engineering Building, which today is the MSU Computer Center.
