Full length card which has enough space to mount a hard drive. This card is not strictly a SCSI card but is an ST-412/506 controller. It appears to be an ISA card, however it has been placed in the Big Book of Amiga Hardware as it was advertised as an Amiga card, probably made with the Amiga in mind. However, as it's an ISA card you will need some sort of Bridgeboard to give you active ISA slots, or possibly even a Busboard with active ISA slots.
