I ran a dead test cartridge because I don't have a keyboard or other means to test things. The dead test cartridge reports the computer is working and chose. No problems plays the audio octaves test repeats over and over and over. Does not come with keyboard or keyboard, cable or power cable. Only the main unit. I've supplied lots of pictures. The unit has some damage to the front bezel otherwise it's a pretty decent specimen selling this unit as it is I've tried my due diligence to make sure this is not junk. I hope it goes to somebody who can put it to good use
