Given the reference to the Amiga, almost certainly SCSI-1, i.e. 8 bit wide
single-ended HVD, clocked asynchronously at low single-digit MHz.
The A2091 (and thus presumably the A590) was a pretty hateful controller, but
the main sources of pain were its shoddy firmware and the limited Zorro-II bus
rather than the SCSI interface. Perhaps the third-party GVP controllers swapped
it around so the firmware was great but the SCSI side sucked.
