The ATbus controller used by HP/Apollo in the DN35x0 and DN4x00 systems is the Western Digital WDC7000 controller. This is an ESDI disk controller that can handle the 697MB disk (Maxtor XT8760E, Micropolis ???), the 348-FA disk (Maxtor XT4380E(?), Microp. ???), or (if I remember right) the 170MB disk. (It can handle up to 2 _identical_ disks). It also provides an internal SCSI connector and an external SCSI port. You can hook up an internal SCSI floppy or cartridge tape, in addition to the external SCSI devices (disks are _not_ supported). You cannot have a non-SCSI floppy/tape drive, and have the SCSI bus enabled. There are minimum motherboard revs needed to support this controller. Offhand, I don't remember the number for the DN3500 series (rev25 comes to mind for the DN4000, and rev07 for the DN4500, but don't quote me). > 2. What is required to actually operate the drive ?

You need sr10.2, or sr10.1 and the PSK (and patches) in order to use tar and/or Omniback (you also need Omniback V1.2 to use Omniback). To use the Domain/OS utils wbak/rbak/rwmt you need to have 10.3 running. -- jt -- John Thompson Honeywell, SSEC Plymouth, MN 55441 thompson@pan.ssec.honeywell.com Avoid the rush -- Procrastinate Now!
