It's the ATARI PC-4, but the German version, which sold under the name Mitac Paragan 286ve. The monitor is an ATARI pc5 monitor though. The Mitac version has the same orientation as the computer Elon has. They also have pics of the other models so you can compare on this link. Hope it's proof enough. http://www.ataripc.net/pc4-286/mitac-pc4-germany/
