This is for a complete Bernouilli system, its a 2 drive system, cable, and ISA SCSI card, including 2 good discs, and lots of documentation including original disks in 3.5 and 5.25. I did not test the install software disks. PC in pics/video NOT included, but I used for tested, tested via a Dell Optiplex GX1 system under Win98SE, able to write/read/format disks, even did scan disks on them. This is for a serious hardware enthusiast/hobbyist only, don't bid unless you completely understand what this unit is and how it works.
