Ext Backup RMA means this is the backup memory cart but ithout more info it's bit hard to elaborate...
It's gray colored, it was found attached to a gray colored JP Saturn at my local flea market. The cart itself has "SEGA" branded on the back. Other than that... I have no clue.

Nor do I have anyone handy who could test this thing for me.
