Profiles took their own card. Had to be matched (hard coded) to the size of the HD. They were not SCSI as far as I know. Siders were not SCSI. they were SASI. Not sure what you would call the Profiles interface.

Not used on the IIc smart port.

If you look in the the second picture. From the back, you can see the top half does not match in color the half of the plastic case. Which leads me to beleive that it is not a proto type. More like some painted and re did the top of the case.
