I don't think I tried an Adaptec 1542, but I suspect it's way too "smart" to
work with SASI drives.
It's been a while since I used the controller, but IIRC it was an old ISA
controller card like a WD7000 or Seagate ST-01/ST-02. Any early SCSI-1
controller should do - that was before SCSI became "smart" - and the
messaging between the controller and the device (HDD) was minimal. A SASI
device on such a controller will respond "well enough" to "look like" SCSI-1.
As I said before - DO NOT mix a SASI device with a SCSI device on the same
controller - or strange things can happen (don't ask).
