The 1987 ROM uses jumpers on the card to define the partitions on the drive.
These partitions cannot be greater than 32MB and only two partitions are
supported. The manual should be considered a MUST HAVE.
The 1989 ROM is similar to the 1987 ROM in functionality, but it has an annoying
habit of shutting down the drive after a period of inactivity. It needs an
access attempt to start it up again, but this access will return a failure error
code (ok when you can redo the action but not too good otherwise :). A plus in
its favour is that the jumper settings are available from the utility software.
Because of this, the manual is not a necessity.
The 1990 ROM gets around the problem of jumper based partitions by assuming that
each partition on the drive will be 32MB (or as much as is left less than 32MB).
This ROM will therefore support > 60MB of storage on multiple drives. The
drawback is that only two partitions can be accessed at a time. The ROM supports
switching them in and out at boot time (hold down the Open Apple key). The
jumper settings are once again available in the utility software.
For the sake of compatibility with the Apple Partition Map, (do you wish to use
the same drive on a RamFAST or Apple SCSI card? or on a Macintosh?) the CMS SCSI
card should not be considered.
However if you just wish to access one 60MB SCSI hard drive from an Apple II,
then the CMS card will do the job well.
The CMS SCSI card has one advantage over the RamFAST and Apple SCSI cards. It
can be used to share a hard drive between computers. For example it is possible
to use two 1989 ROM cards (in an Apple //e and a //gs) to share a 60MB drive
with a second //gs which has a 1990 ROM card.
The CMS utilities disks for all ROM versions are available on the following
mirror of the ground archive:
http://www.apple2.org.za/mirrors/ground.icaen.uiowa.edu/apple8/Utils/
CMS.NOV87.SHK
CMS.OCT89.SHK
CMS.APR90.SHK
I also scanned in the manual for the 87 ROM and currently host it here:

The manual is also available on GSWV at http://apple2.org.za/gswv/a2zine/Docs/ .

014- Does it matter when I power-ON my SCSI hard disk?
From the Apple IIgs Owner's Reference, page 267:
"In order for the Finder to recognize a hard disk, the hard disk must be
switched on and up to speed before you start up (or restart) the computer.
