AbstractA method of operating a finite state machine to control the sequence of operations for transferring data through two or more rotating data buffers. The data transfer is either from a SCSI bus to a disk memory system, or from a disk memory system to a SCSI bus. The finite state machine is self-sequencing after initiation from an external source. An apparatus for implementing the method is also presented.
