 - (dash) means you are running now.
   (blank) means you are sitting in core.
 * (asterisk) means you are swapped out. ** means upper segment also swapped.
 / (slash) means you are running spacewar on the PDP-6.
 \ (backslash) means you are in spacewar on the PDP-10.
 X means you are running spacewar on both the 6 and the 10.
 ⊗ means you have locked yourself in core with the LOCK UUO (naughty!).
