A screenshot of the GEM desktop environment. It looks almost like the Atari ST TOS desktop and fairly reminiscent of the LisaOS.

   Wait, what’s this? It looks like an Atari ST screen? And it’s running on my #AppleLisaClone?!

   This is #GEMDOS from Digital Research (the CP/M folks) for the #AppleLisa.
