You'll need both UNARC and DISKCOMM to unpack this double sided Disk.

This is an INFODISK of the German Atari 8-bit vendor POWERSOFT. You'll find
its catalog on side 1. Boot this side with BASIC disabled. Shortly after
booting you'll see an intro screen. In order to go on press the START key.
In a few moments you should be able to see the main menu. There you can
select from different menu entries either using the cursor keys,
the joystick in port 1 or a numerical keyboard in port 2.

Sometimes you'll need to flip the disk in order to load another topic.

You can also boot side 2 of the disk. This time leave BASIC enabled.
Upon loading you'll be presented with the title page of the game "Mission X".
The message on the screen tells you to wait app. 2.5 minutes.
After initializing press the START key and you'll get into a neat helicopter
game.
