Abstract
A circuit is provided for control and data transfer between a standard data storage device interface and one of a choice of several host computers. Parallel transition memories in conjunction with a buffer memory under common control of a buffer manager increase the transfer efficiency between the data storage unit and the host computer. Selectable register banks provide interface compatibility with multiple host computers for implementation of the invention.
