I have actually tested this card several years ago and had it working just fine with an internal SCSI hard drive. This particular card supports both internal and external SCSI hard drives for use with the MacWorks Plus version of the Mac OS. I do not have the software disks handy but they are easy enough to find online.
This board is in excellent working condition. An excellent upgrade for your Lisa 2 or Macintosh XL computer! Please view my other items for sale! The item "APPLE LISA SCSI HARD DRIVE Expansion CARD w.
