SCSI Daisy-chaining: Can I do this?

[fermilevel@aol.com (FermiLevel)]

I want to daisy chain the following SCSI devices together:  IIGS-->TMS
Shadow HD--->SyQuest EZ135--->Apple CD300e---->Mac 270c.  I have a RamFast
3.01e in the GS.  I have everything hooked up and working fine except the
Mac Powebook 270c.  That's where I get afraid!  Can both computers see all
the SCSI devices at the same time?  The Mac has SCSI ID=0, so all the
others are set to 1, 2 & 3.  I fear that the Mac will puke on the ProDos
partitions on the Shadow HD.  Can anyone help calm my fears?  Also, I did
hear that someone makes software for the Mac that will allow the SYSTEM to
recognize ProDos volumes, not just ProDos 3.5" disks.  Does anyone know of
this?
