This is a bare pcb cartridge. Insert into 130xe/65xe system in REAR cartridge slot with components facing DOWN (BACK UP CARD FACING UP). Insert into XEGS with components on cart facing to the rear and away from you. You can run this without a case as its a simple inexpensive diagnostics cart.. This is standard practice on Commodore, Atari, and other systems. If you really want a cartridge case you can look for a cheap/broken game cart and install it into the case.
