Here we have an original Apple High Speed SCSI Card with cable as shown. Super fast for the time with DMA. Was pulled from a working IIGS. Was used to control a hard drive but I understand it also will control an appropriate CD ROM or laser printer. Includes a copy of an original SCSI Utilities Disk.
Owners manual available atapplehsscsi.pdf
Vintage electronic expansion board and as a result sold as is with no returns. Questions welcomed and thanks for looking and make an offer !
