3 models, 6 slot 1.6” and 12 slot 1”, auto termination wide Single ended SCSI (not differential). There was also a Fibre Channel version which was very rare if I remember correctly.

Each disk has a separate SCSI ID, from memory there is a starter ID switch, cannot remember if the 12 slot was more limited due to number of disks.

You need Single ended or the SE/LVD controllers.
