  14. Sorry, but the SCSI support in the RT is only for the IBM differential
  15. SCSI adapter, used to attach, for example, 9332 and 9335 disk drives.
  16. These are huge, expensive, external disks (400MB!!!) which needed the
  17. long cables which the more elaborate differential SCSI permits.
  18.  
  19. Don't know anything more about it; 
  20. don't think you can attach anything but 40MB disk drives to the adapter
  21. you now have.  
  22.  
  23. Your best bet is to find someone who would let an "EESDI" disc controller
  24. card and some 114MB or 310MB disk drives go cheaply;  trying to support
  25. devices not originally supported in AIX is probably NOT the way to go.
