ABSTRACT:
An improved interface system based in part on the SCSI standard is provided. A single cable data bus simultaneously transfers several bytes of information between two devices. The interface system transfers multiple-byte commands, messages, status information or data in a single parallel transfer. A microsequencer is provided to permit data transfers across the interface without requiring burdensome attention from a processor in a device involved in the transfer.
