A seven-page English translation of Pukhov's 1985 story, with the full Lunolet-1 program listing and the game's worked setup (machine-assisted translation).
Today the Science Fiction Fan Club presents our new section "Electronic Games Club" (see page 6). Therefore, the proposed text is addressed first of all to those science fiction fans who have already studied the articles of the section "For All Professions" and know how to handle programmable microcalculators "Elektronika B3-34", "Elektronika MK-54" and "Elektronika MK-56".

Entering various considerations into the typewriter regarding the size of the "huge I must say that, in addition to numerous letters, visitors meteorite" and the magnitude of its "cosmic velocity", come to us quite often.

He sighed bitterly and was sad for about five minutes as we made our way home. Then he went for a walk.

I've flown a spaceship only once in my life. "Dad!" he said. "Where are you going?" Of course, in my youth, like many of my peers, I dreamed of becoming a cosmonaut. But these dreams were dispelled "To the spaceport." at the very first medical examination: overloads of more than three G's made me feel sick. Those who could not "Ah," He waved his hand in disappointment. "I've already withstand five G's were not allowed to further tests. been there. It's boring there. They won't let you anywhere." Reluctantly, I had to take back my documents. I applied for computer engineering, successfully earned my diploma six "I'm not going to the port," I explained. "I'm going to the years later, and - irony of fate! - I was sent on assignment to local lines. It's a small area off the main field. The airliners the Moon, to the S. P. Korolyov Center. I have been you flew on aren't there. Only local lunolets." working there ever since. "Real ones?" he inquired. After inorganic oil was found in the neighborhood, the Center grew greatly. Now it is a real city with a population "Certainly not toy ones. But they are small - only two tons of about three thousand people. The domes covering it are of empty weight. Or rather, empty mass. Everything here connected by tunnels. Like in the subway, only the walls are weighs six times less than on Earth." transparent. These are, roughly speaking, large pipes stretched right across the lunar surface. One of the tunnels "I know," Sergei waved it off. "What are you going to do leads to the airport terminal. The spaceport of the Center is there?" an extensive complex, it serves the entire Solar system. By the nature of my work, I often visit the port, because ships "Work," I shrugged. "The cyberpilot on one of these are packed with electronics, sooner or later something goes machines has failed. We'll have to take a look. If it's out of order, and repairing computer equipment is my nothing, I'll do it on the spot. But if it's something specialty and direct responsibility. serious…" The incident I mentioned occurred in the summer of 2087. "Will you go to the control room?" His eyes widened. Our work is cyclical: four months of work, two months of rest. Usually on Earth. Relatives also come to stay I couldn't help but burst out laughing. sometimes - the Earth-Moon passenger line opened a long time ago. That summer my son, Sergei, came to visit me. I "What control room! It's just a cabin, with two chairs. You haven't seen him for several months, during which time he can't turn around." has grown a lot. He's almost twelve, and he raves about space exploration. My wife and I hoped that an independent "But are the instruments there?" He continued the trip to the moon would make him very happy. And he interrogation. "Are the controls there?" himself, as she reported, did not sleep at all the night before the flight. "Of course," I said innocently. "Where else would they be?" "Take me with you," he demanded. I waved towards the spaceport. "And they also produce liquid oxygen." "But it's not a game," I tried to explain. "It's a job…" "For spacesuits?" He pronounced the word "spacesuit" "Dad!" he said. "You promised me." with a special expression. I grinned at him: "Just don't tell Mom," I said, giving up. "And for spacesuits, of course. But mostly they take it to the same gas stations. After all, fuel will not burn without A few minutes later, the electric car was speeding us an oxidizer." towards the spaceport. The streets were deserted at this hour - everyone was at work. Shortly before the airport terminal, We walked in silence for a while.

There were about two dozen of them - old but reliable machines. In the first approximation, it is a rounded cone "He's with me," I said.

He's just a kid." On the side of each lunolet there was an identification The watchman thought for a minute. This situation was number - two digits inscribed in luminous paint and obviously new to him. surrounded by a black border. Ours was on the edge. Without further adventures, we climbed inside. At the sight "All right, let him go. Under personal responsibility." of the numerous dials, Sergei's eyes lit up. We were given spacesuits without any problems. Of course, "Is this a real ship?" he asked. it was too big for Seryozha, but only a little bit - it's not that small for me. I understood. On Earth, there are similar machines in every recreation park. Attractions. Get in the hatch and experience "These are standard oxygen tanks," the watchman warned. all sorts of sensations. "They have enough air for two hours. Will that be enough?" "It's the best," I said. "Of course. An hour is enough for me with a guarantee. Twenty minutes there, twenty minutes back, ten minutes on "And how do you fly it?" the spot. Well, ten for all sorts of complications." I chuckled. "I see," the watchman said good-naturedly. "Just don't let there be any complications. Ok?" "It's as simple as that. This box here," I pointed with my finger, "is called cyberpilot.

There was a rumble below us, flames "I don't know," I said.

It was pointless to go up. Going down (and next liters of fuel…" to the red button I saw another one, "Reverse thrust") would be even worse.
