The IIgs makes no assumptions about slot 6 if it is set to Your Card. I
have my Superdrive card (Apple 3.5 Disk Controller Card) in slot 6, and
SCSI cards work find there as well.

I would expect the CD300e Plus to be recognised by the GS/OS drivers for
data storage, but it might not work for booting as the original Apple
SCSI card firmware may not recognise the CD300e Plus as a CD-ROM drive
(the card's firmware was written for the much older CD-SC).

It won't be recognised for controlling audio playback, as Apple switched
from a proprietary audio command set to the standard SCSI one in the
CD-150 and later; the Apple II and IIgs audio CD control software from
Apple only supports the proprietary protocol used on earlier drives.
(There were some third party attempts to rectify this situation.)

Termination power seems the most likely theory. All my SCSI hard drives
supplied termination power so I never worried about it for the Apple II
SCSI cards.
