Is it possible to chain those 70Mb winchester disk drives on old DN300 or DN330 workstations? I'm saving a DN330 from the dumpster, and 140 Meg would be a lot nicer than 70 for a home box. I have R'd To the remaining ancient F Manuals, but could only find info on chaining DSP80 storage modules, so I realize this may be a long shot. Scavengingly, yours... -- George Zipperlen george@apollo.lap.upenn.edu george@hyper.lap.upenn.edu ...!{rutgers, uunet, mit-eddie, decwrl}!upenn.edu!apollo.lap!george Blatant plug for funky-music@apollo.lap.upenn.edu "Won't be no Static" -JB

We also have a number of those boxes lying around. Does any know what interface the drives use (SMD perhaps?). Their model number is SMSD-70-... Is SMSD yet another interface? James S.

I asked our filed service rep about this a long time ago. The answer was no. The controller for the DN3xx series disks does not support multiple drives according to what I was told. -- David Krowitz krowitz@richter.mit.edu (18.83.0.109) krowitz%richter.mit.edu@eddie.mit.edu krowitz%richter.mit.edu@mitvma.bitnet (in order of decreasing preference)

The guy was only partly right. The controller on the dn3xx has two st506
ports, and you can put two disks on it. Normally one would be a floppy and
one would be a winchester. In theory you could plug in two winchesters, but
you would need to patch the os to deal with this. I don't know anyone who
has tried this, but I know someone who is about to.

The phrase "MSD" used to stand for "Mass Storage Device" in the early Apollo (pre DN3000/4000) price list. For instance, the 500 MB CDC 9715 drives that came with the DSP80/80A/90 file servers were listed as MSD500-M in the price list. These (CDC 9715) drives are indeed SMD drives. I'm not certain about the DN300/320/330 drives. They might actually be ST506(?) drives. -- David Krowitz krowitz@richter.mit.edu (18.83.0.109) krowitz%richter.mit.edu@eddie.mit.edu krowitz%richter.mit.edu@mitvma.bitnet (in order of decreasing preference)
