- 15. Lunar Lander
- You are descending to the floor of a 250-foot crater. The right side of the TV display
- shows amount of fuel, feet from bottom and fall rate per cycle. Lenght of fall rate
- cycle changes from about 1/4 second to one second. The fall rate increases by one
- foot per second/per cycle. The computer will update the display only at the end of
- each cycle.
- The left side of the display shows the Lunar Lander descending from 250 feet. The
- Lander will first appear at one of sixteen locations. It will then slowly drop down
- the crater. The crater walls have rock formations protruding from them which must
- be avoided. If either rocket motor should touch any part of the crater, the Lander
- will explode in a cloud of smoke and disintegrate. (Remember, these are atomic
- thrusters and react like miniature atomic bombs upon impact).
- When you reach 32 feet, the display will change, and you will see the crater floor.
- You must now ladn between the rock formations on the floo and maintain a minimum fall
- rate. As you drop your fall rate to zero, you soon discover that the Lander becomes
- more and more unstable just as any hovering object would. And now with perfect skill
- you guide the ship in for a perfect touch down, or?
- How to Play VIP Lunar Lander
- 1. Load the CHIP-8 interpreter at 0000-01FF and teh game starting at 0200.
- 2. Key 2 controls the thrust of the Lunar Lander. One tone beep equals one pound
- of fuel and one foot of thrust.
- 3. Key 4 controlls the horizontal stabilizing engine, and moves the Lander one
- foot to the left per one pound of fuel.
- 4. Key 6 controls the stabilization to the right.
- 5. Stabilization controls only react after: (a) a complete fall cycle, or (b) after
- the Key 2 thrust control is pressed. You must be aware of this at all times or
- you will crash even though either key 4 or 6 is pressed.
- 6. At the end of each cycle, the Lunar Lander will move randomly at the rate of one
- foot either right or left. Therefore, as the fall rate approaches zero, the Lander
- becomes more uncontrollable, and your horizontal stabilizers react more quickly.
- (Just like the real thing).
- 7. If you land too fast, the Lander will bounce and flip over.
- 8. If you run out of fuel, the Lander will crash.
- 9. You will not be allowed to go above 250 feet. If you try to do so, you will just
- waste precious fuel.
- 10. Once you reach 32 feet and move into the landing display, you will not be allowed
- to rise above 26 feet. Trying to do so will waste more precious fuel.
- 11. Game options
-
- You may select one of three options at the begining of the game.
- Option 1: You start at 250 feet. You are given 150 pounds of fuel. You must land
- at 5 feet per second or less. The initial descent display is easy to
- maneuver through.
- Option 2: You start at 250 feet. You have 200 pounds of fuel. You must land at 3 feet
- per second or less. The initial descent display is hard to maneuver through.
- Option 3: You start at 32 feet. You have 100 pounds of fuel. You must land at 3 feet
- per second or less. This display allows you to practice landing.
- You should consider Option 2 as the complete game when trying for Astronaut Ratings.
- 12. Astronaut Ratings
- The computer will award you with ratings depending on how good a lander you are.
- You will obtain the rating of Astronaut by landing without regard to fall rate or
- fuel. You must not exceed fall rate, or zero fuel.
-
- You will obtain the rating of Astronaut Pilot, by ladning with regard to fuel. 80
- pounds or more if you land between the two rock formations on the floor, and 50
- pounds or more if you land between the crater wall and a rock formation.
- You will obtain the rating of Astronaut Captain by landing the ship with regard to
- fuel as per above and if the fall rate is two feet per second or less. (Not an
- easy task, as you will soon discover).
- 13. About Graphics
- This game has some interesting graphic displays when you run out of fuel, crash,
- land too fast, when you land successfully. I will leave them to your discovery,
- as they are fun to watch.
- 14. Landing Sites
- The final landing display will appear somewhat like the illustration below
- (VIPG1-15.jpg). You may land in any of the three locations pointed to. To land
- between the crater walls and rock formations, you will have to first bring the
- Lander to a zero fall rate while hovering in the center landing area. Then bring
- the ship up and just over the rock formation, and let it drop down to the landing
- site. At the last moment, a few taps on the thruster button will slow the lander
- to the required fall rate. It will take you many tries to land here, but don't
- give up, it can be done!!
- NOTE: VIP Lunar Lander requires at least 3K of RAM. RAM memories are available to
- increase your VIP from 2K to 3K at your local computer store or by contacting:
