All the hardware here has been tested and working as it should. Comes with the 520 adapter, OEM Power supply, Tank mouse, joystick, and many xtras as seen in the photos. Not every exact pamphlet is here from this original bundle but the main bulk of the bundle is here and lots of xtras not originally included in the bundle are as well. Lots of original games, various programs, and lots of demos and antics/ amigo times disks. I haven't tested them all of course. But from the ones I did test they all worked. There's also a brand new work bench 3.1 included. The box has seen better days but it is however still presentable and usable. Everything else is in good overall condition. I spent a couple hours playing games and loading other various disks and everything seemed to be up and running just fine.
