Thanks, Matt, for the interesting report on the SCSI situation, but I think
that a major question that a lot of "other" drive owners would like to know
is, "Can I purchase an Apple SCSI card and then use it to gain the full
capabilities of GS/OS?" If that is too simple of a question let me get into
some specifics.
o May I take an Apple SCSI card, use it to partition my CMS card
in the Apple partitioning scheme and then have access to the
full 80 megs of my hard drive through partitions while not
using extra slots?
o Can I use the Apple low-level utilities for diagnostics on my
CMS drive?
o Can I still daisy-chain my other SCSI devices into the Apple
card?
o Why does Apple not use a chaining scheme standard in most all
other SCSI devices, for the Apple II when they do for the Mac?
Thanks
Todd South

You seem to have missed one of the basic points of my post: although most SCSI devices *should* work on the Apple II SCSI Card if they work on the Macintosh, Apple can't promise that they will. Only the manufacturer can know for sure, or someone who knows an awful lot about Apple II SCSI implementations spending a lot of time with the drive. That's it. That's as far as can be said. Any "will XXX drives work" questions can only be answered definitively by the manufacturer, or empirically by someone who's used them. >o Can I use the Apple low-level utilities for diagnostics on my > CMS drive? > What low-level utilities are these? If you mean "low-level" in the Brian Willoughby sense of the word, I don't know that there are any. If you mean low-level in the ADU/Partition sense, yes. >o Can I still daisy-chain my other SCSI devices into the Apple > card? > Who said you couldn't? >o Why does Apple not use a chaining scheme standard in most all > other SCSI devices, for the Apple II when they do for the Mac? > Again, who said we didn't? On my IIgs here at work, I have a 20 MB SCSI drive in front of an Apple CD-SC both on one SCSI card. If I run across a CD with more than one ProDOS partition, I won't be able to get to the second one (since P8 only allows two devices per slot except in slot 5, and mine's not in slot 5), but up to 32 partitions are available under GS/OS 3.0. >Thanks > >Todd South > >-- ----------------------------------------------------------------------------- Matt Deatherage, Apple Computer, Inc. | "The opinions expressed in this tome Send PERSONAL mail ONLY (please) to: | should not be construed to imply that AppleLink PE: Matt DTS GEnie: AIIDTS | Apple Computer, Inc., or any of its CompuServe: 76703,3030 | subsidiaries, in whole or in part, Usenet: mattd@apple.com | have any opinion on any subject."
