+SPACE-WAR
+
+     This is Spacewar for the IMLAC PDS-1.
+
+     Spacewar is controlled from the switches on the Programmer's
+Console of a PDS-1.  The keyset and keyboard are also used to a limited
+extent.  The meanings of the console switches are as follows:
+
+
+       SHIP 1          CONTROL          SHIP 3          SHIP 2
+    (stubby ship)                  (triangle ship)   (needle ship)
+  |               |               |               |                |
+  | 0   1   2   3 | 4   5   6   7 | 8   9  10  11 | 12  13  14  15 |
+  |               |               |               |                |
+    <- ->   a   f   s   g   3   r   <- ->   a   f   <-  ->   a   f  
+                    p   r   r   a
+                    i   a   d   n
+                    n   v       d
+			i   s   o
+			t   h   m
+			y   i
+			    p
+
+
+     For each ship, the left button is counter-clockwise roll, the
+second is clockwise roll, the third is rocket thrust, and the right-
+most is bullet firing.
+     Putting both rolls on at once causes warping.
+     Putting thrust and both rolls on at the same time makes you
+invisible or visible, depending on your current state.
+
+     Control switches:
+
+Switch 4 - In down position, turns on spin mode, in which angular
+	   momentum is conserved.  In non-spin mode, the ship will not
+	   rotate if neither rotation switch is down.
+
+Switch 5 - In down position, turns off the Sun's gravity.
+
+Switch 6 - In down position, adds 3rd ship (triangle ship) at start of
+	   game.  If this ship is in the game, it uses the keyset (to
+	   eliminate the tangle of fingers on the console switches.
+
+Switch 7 - In down position, randomizes starting positions.
+
+     The rightmost four keys on the keyset will also control ship 1 or
+ship 3 (depending upon whether there are 2 or 3 ships in the game)in a
+manner similar to the four switches.
+
+     Typing "BREAK" causes the game to be interrupted into a mode where
+the scores are displayed and keyboard commands may be typed.  Commands
+currently available are:
+
+	R - reset scores to zero.
+
+     Spacewar loads into the high 4K of the IMLAC and thus may be
+loaded on top of SSV without destroying it.  To return to SSV, type
+control-Z on the keyboard.
