A Mass Memory Unit for the Space Shuttle orbiter
Abstract
The paper describes a high-capacity, medium access time data system, the Mass Memory Unit (MMU), developed to interface with the General Purpose Computers in the Space Shuttle system. The MMU, which uses magnetic tape as the storage medium, will be used to provide display format storage and will function as an auxiliary memory, used to store and load/reload all phases of flight/ground software. The MMU is able to store 1.31 x 10 to the 8th bits and has a nominal access time of 600 millisec. The data transfer rate is 10 to the 6th bits/sec and recording is at a packing density of 5000 bits/in.
