Abstract
A general purpose interface is provided for connecting a floppy disk drive to a parallel port of a personal computer. The interface comprises an interface circuit and software driver circuit operated by the CPU. The interface circuit emulates the internal bus circuit in the CPU and can be used with virtually any disk controller. The interface circuit uses gate arrays as state machine logic elements to perform various functions, eliminating requirements for a microprocessor and plural memory chips.
