Abstract
This invention relates to personal computers, and more particularly to a personal computer using a small computer systems interface (SCSI) controller for controlling data transfer with storage memory devices such as fixed or removable media electromagnetic storage devices. The personal computer has three interface circuits and a controller processor. The interface circuits control exchange of data among the system central processing unit (CPU), a controller processor, and one or more storage device(s) connected to a SCSI bus. One of the interface circuits includes a least one register for storing data indicative of the content and status of a plurality of sequences of commands ("threads") issued or to be issued to the SCSI device(s).
