I'd like to find out what is available in the following categories for an Apollo Domain 3500 workstation. Both hardware and the necessary software would need to be found. SCSI adaptor: we have a portable SCSI tape drive that could be used for backing up the hard drive in the Apollo. How can we get it connected? Floppy drive: this is another backup option, and could also serve for easy Apollo (and the net) <--> IBM PC/AT file transfer. Can one get a 1.2 Meg 5.25" or a 1.44 Meg (or 720K) 3.5" drive? Can it read/write MS-DOS format files? Or only UNIX files? Both? Thanks. - Moshe Braner Cornell Theory Center, 265 Olin Hall, Cornell University, Ithaca, NY 14853 USA (607) 255-9401 <braner@tcgould.tn.cornell.edu> (INTERNET) <braner@crnlthry> (BITNET)

It does not read/write low dense floppies very well. As for UNIX floppies you can either mount the floppy, use wbak/rbak or tar. The cost, if you have a hard disk, is about $500 for the floppy. The PC software emulator is about $500 and the PC hardware emulator is $2K-$3k. -- Roger E.

The PC >software emulator is about $500 and the PC hardware emulator is $2K-$3k. There is a program I wrote called PCdisk that supports high and low density MS-DOS floppy disks without the need for the Apollo software or hardware emulator. Its cost is less (and performance better) than the Apollo products: $200 for the first node and $100 for nodes after that. It can also support a 3.5" floppy, if want to add a non-standard drive to your node. (My DN4000 has a cartridge tape in the node and a 5.25" and 3.5" floppy in an auxiliary cabinet.)

Roger Benz (reb%quintro%tiamut.uusp@uunet.uu.net) stated in a recent message that mounting, wbak/rbak, or tar to high density floppy is an acceptable backup solution. While I have not tried this yet under SR10 (or SR9.7, either), I did extensive tests under SR9.6 and found that sizable items stored on floppies by any of these methods were almost always unrestorable without data losses. Until this situation is amended, DON'T COUNT ON FLOPPY BACKUP! Besides, cart tape is (somewhat) faster. (:::::::::::::::::::::::::::::::::::::::::::::) ) Steve Albrecht IntelliCorp,Inc.
