*    Need 3C1068 Old to New SCSOI cable.

**   If a second drive is added to an expansion unit, you must use the same
     size disks in that expansion unit.

***  The 106MB Disk Option can be used with either the 106MB Disk
     Expansion Unit or the 70MB Disk Expansion Unit.  If used
     with the 70MB Disk Exp Unit, the 106MB Disk Option must be
     re-formatted to 70MB.  However, 70MB Disk Options can NOT be
     reformatted for use in a 106MB Disk Expansion Unit.

**** The 150MB Tape Drive cannot be supported in a Disk Expansion
     Unit attached to anything other than a 3S/400.  Reason:
     only the 3S/400 bus supports "disconnect/reconnect"
     and thus can support the two devices (disk and tape)
     on the single SCSI bus of the 150MB Disk Expansion Unit.
