Full length Zorro II SCSI card which has both an internal 50pin SCSI connector, and an external 25pin SCSI Connector. Additional memory can be added in the form of ZIP chips. The card was supplied with a 105MB SCSI Hard Disk which is accessed via scsi.device. Please note that you may have to use the HDToolBOX which was supplied with the card because it writes special bootblocks to the hard disk, which the Add2000 requires.
