Yes that is a common SCSI upgrade to the 512K, designed to replace the battery cover. It required an upgrade to 128K ROMs and most likely has 800K drive upgrade as well. The Plus did not debut in Platinum. Check out Wikipedia for a history of the 512K & Plus. That 512K by virtue of using HD20s most likely had the 800K drive upgrade as well, and bought the Plus keyboard upgrade.
