H.D.D

You are a hard drive.  You must save data from RAM to the disk, and when the CPU asks you to give him some data you must do it quickly!

Use Arrows to rotate the hard drive disk and move the needle.
Press A to move data from RAM to the disk (to the place pointed by the needle).
Press S to move data from disk to the RAM.
Press Space to move data from disk to the CPU to complete tasks (only the task at the top can be completed).

There are some special SYS segments that you can't move.

You lose when your RAM has overflown.
