Up for sale is an a 590 hard drive plus for Amiga. It is my best guess that it goes with the Amiga 500 and plugged into the port on the side of the 500 console.I am selling all of the remaining inventory of an old Amiga Commodore dealer. Everything is sold as is for collectability purposes only. Please zoom in and take a look as all compatibility issues are that of the buyer. Many of the items still have the original price tag attached to it. Happy Amiga hunting!
