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.
