You will need a bus logic BT-646S Fast SCSI 2 MCA card, hard drive( SCSI
)
 power & drive cables this is the only card I could find to work. This
isn't cheap to do.
But you can always reuse the large SCSI & CARD IN OTHER PC's You will
also need the setup disk the option disk comes with the card. Upgrade
the reference disk with the options disk. The reference disk is the
setup disk.
