YOU ARE Commander of the starship ENTERPRISE, 
with a mission to seek and destroy a fleet of 
KLINGON warships (from about 8-25) which is 
menacing the United Federation of Planets.  You 
have a certain number of stardates in which to 
complete your mission.  There are one to four 
Federation STARBASEs for resupplying your ship.

You will be assigned a starting position 
somewhere in the galaxy, which is divided into 
an 8X8 quadrant grid.  The astronomical name of 
each quadrant will identify it.  Each quadrant 
too is divided into an 8X8 grid.

On a section map, these symbols apply:

        o   ENTERPRISE    S   STARBASE
        !   KLINGON       *   STAR

You have eight possible commands:

Navigate the starship by setting course and 
engine speed:

Warp engine control - course is a circular 
arrangement of numerical vectors with integer or 
real values (1, 2, 2.5, 5.4 etc.) up to 9 
(equivalent to 1).  One warp factor is the size 
of one quadrant - to go from quadrant 5:5 to 
quadrant 6:5, steer Course 3, Warp Factor 1.

Short range sensor scan (one quadrant)

Long range sensor scan (nine quadrants).  Coded 
as ###, where units = stars, tens = starbases 
and hundreds = KLINGONs.

Phaser control (energy gun), used to shoot at 
the KLINGONs (also have phasers).

Torpedo course data: the same as used in warp 
engine control.  A hit KLINGON is destroyed and 
cannot return fire.  A missed KLINGON will 
return fire.  You are generally subject to 
phaser attack by all KLINGONs in your quadrant.  
The computer may be used to determine torpedo 
courses.
Energy shield control (protection from phaser 
attack).  These require energy to be deployed 
from the ship's supply.

Damage and state-of-repair report.  A negative 
state-of-repair indicates temporary damage.

Call computer.  Here you have six options:
     
      A: Cumulative galactic record - the 
results of all         previous short and long 
range scans.
      B:  Status report - the number of 
KLINGONs, STARBASEs and        stardates 
remaining.
      C: Torpedo data - directions and distance 
to all        KLINGONs in your quadrant.
      D:  STARBASE navigation data - direction 
and distance to        any STARBASE in your 
quadrant.
      E:  Direction/distance calculator - allows 
you to        specify coordinates for travel.
      F:  Galactic region map - prints the names 
of the     sixteen major galactic regions.

Certain reports on the ship's status are made by 
crew members (Spock, Uhura, Chekhov et al.).

KLINGONs are mobile within their quadrants.  If 
you try to manoeuvre on them, they will move and 
fire on you.

Firing and damage notes:

a.  Phaser fire diminishes with increased 
distance between      combatants.
b.   If a KLINGON zaps you sufficiently hard 
(cf. your      shield      strength), some part 
of the ship will suffer      (indicated by a 
damage control report).
c.  If you do not hit a KLINGON sufficiently 
hard (cf. its shield strength), you will cause 
no damage.  You sensors will report this.
d.  Damage Control will let you know when out-
of-commission devices have been repaired.

Your engines will automatically shut down if you 
try to leave the galaxy, or if you try to 
manoeuvre through a star, a STARBASE or a 
KLINGON warship.

If you miscalculate slightly, some shield 
control energy will automatically be diverted to 
warp engine control (if your shields are 
operational).

While you are docked at a STARBASE, a team of 
technicians can repair your ship, if you are 
willing to wait - remember, repairmen always 
underestimate the time taken!

If you destroy a STARBASE, you get a nasty note 
from Starfleet Command.  It you destroy your 
last STARBASE, you will be relieved of command!
