MB87030 Overview
The MB87030 SCSI Protocol Controller (SPC) isa CMOS LSI circuit specifically designed to control a Small puter Systems Interface (SCSI). The SPC can serve as either an Initiator or Target for the SCSI; thus, it can be used as an I/O controller or as a host adapter.
MB87030 Key Features
