  Third-party SCSI device integration? 
 The Question is:
 
We are trying to interface an IBM 9GB SCSI drive (Model: DNES-309170, P/N:
 25L1810) with the DSSI bus as found in the R/RDF assembly in the Satellite
 Mission Control System (SMCS) of the MILSTAR system, through an HSD-10 card.
 The MILSTAR currently uses
Digital R/RF73 drives.  The SCSI drives seem to work fine when installed in the
 R/RDF (holds four drives), but when a R/RF73 drive is installed in any of the
 drive bays, the SCSI drive seems to cause an error on the R/RF73.  If we use
 about ten feet of ca
ble (as we did during bench testing) to connect the SCSI drive and HSD-10 to
 the R/RDF, the error disappears.  Or if we attach a cap. on the "DSSI REQ" bus
 line, the problem also goes away.  We perfer not to have to implement a
 hardware work around.  Any
suggestions?
 
 
 The Answer is:
 
  Please see the existing discussions of third-party SCSI hardware.
