  • Patent number: 5634029
    Abstract: A floppy diskette drive assignment interchanging apparatus for interchanging the drive letter assignments in a computer system is disclosed. The floppy diskette drives have a drive data cable that includes a number of data lines. The interchanging apparatus comprises an interchange control logic and an assignment interchange logic. The interchange control logic generates an optional interchange control signal, the interchange control signal signifies the requirement for interchange when it is in a first logic state, and signifies the requirement of maintaining no interchange when it is in a second logic state. The assignment interchange logic has a set of inputs connected to each of the data lines among the drive cable data lines that require interchanging, and has a set of outputs for outputting the set of inputs with an output assignment of either a forward or reverse order determined by the active and inactive status of the interchange control signal.
