I now have a SCSI hard drive with a couple of prodos partitions and some HFS partitions. I can boot a mac from it and at the sametime boot a IIgs from it thru appletalk or I could connect it and boot the IIgs up alone with it. IT just requires two copies of the IIgs system software. One in a prodos partition and one in a HFS partition. You can not even use an alise to a copy on a prodos partition, bummer :<
