The arcade game of ping-pong was rewritten by Fajin and may have been even more efficient than the one on Odyssey, but it didn't work, and Daheng could use it for internal testing, but it should never be used for commercial purposes.

Fortunately, Zhang Heng had already prepared, and he instructed He Jie: "Please Director He bring the document on the first floor of my safe." ”

A pile of A4 paper was gently placed on the table, Fa Jin immediately flipped through it, Zhang Heng looked at him who was engrossed, and muttered in his heart, I don't know if Jiexi has fulfilled her duties?

Fajin only took five minutes to read dozens of pages, and looked up at Zhang Heng with admiration, "Boss, it looks very playable, I have to admire your whimsy." ”

Zhang Heng is not surprised by his reading speed, although the program he wrote down with the compilation seems cumbersome and lengthy, but after each paragraph of the functional module, English annotations are added, presumably he who is familiar with the compilation can easily see the function of this program, and his judgment on playability also fully demonstrates the excellence of his thinking ability.

"It's also the first time I've used 4004 assembly language programming, and I haven't debugged it yet, so I need you to port it to 8008 and then debug it well. ”

In his previous life, Zhang Heng wrote this program on the 51 single-chip microcomputer system, and it was written in a more primitive 4004 assembly language, and there would be no problems with the structure, and there were likely to be some errors in the syntax and operation address, after all, he had only read the 4004 instruction set twice, and he was not very proficient at all.

"Okay, the four of us should be able to do it today. Fa Jin happily agreed, "Just use the PL/M language that Daheng has just been authorized, and the hardware can be ported quickly after the hardware is upgraded in the future." ”

This is the consciousness that R&D personnel should have, Zhang Heng nodded with satisfaction, and saw that the other three were getting together to study the program, and motioned for Fajin to follow him a little farther.

"Federico, is there anything else you need the company to do about life?"

"No, the company is doing well enough, and Serena and I are very satisfied. ”

Seeing that he was indeed very satisfied, Zhang Heng turned to ask about work, "Then here, do you have any problems getting along with my employees?"

"They were wonderful young men, open-minded and eager to learn, and I had never felt so respected and needed. Faggin had a smile on his face, "Boss, thank you!"

"That's good!" Zhang Heng smiled, "On the premise of not involving Intel's technical secrets, I ask you to teach them more things." ”

"I will, you gave me such a good treatment, I don't want to go if I don't come up with something. Farkin humorously.

"Your efforts will not be in vain. Zhang Heng took a deep look at him and walked to the table, "Let's go and see what suggestions they have." ”

Faggin looked at his back, stopped talking, and followed.

The three young engineers didn't make any suggestions, and even though the notes were annotated, they still couldn't fully understand the program's functionality, or imagine what would appear on the screen when the program was run.

A geometry that can be varied, what's the use of that?

Could it be that the boss wants the children to understand the math textbook more deeply?

Only Lu Yun, who was born in a professional class, can vaguely conclude that maybe the boss wants people to play a game similar to "Tangram".

The question is, are there any adults willing to spend money in bars or other public places to play games that are inevitably considered "childish"?

For understandable reasons, he didn't voice his concerns, and was ready to wait until he saw the specific results before raising his doubts with his boss alone.

LU YUN'S CONCERN IS ACTUALLY SOMEWHAT JUSTIFIED, THIS GAME, WHICH HAS BEEN RENAMED "CHINA CUBE" BY ZHANG HENG, IS ACTUALLY NOT VERY SUITABLE FOR ARCADE MACHINES, AND ITS BEST CARRIER IS ACTUALLY HANDHELD GAME CONSOLES, SUCH AS "GAMEBOY" AND "GAMEATCH".

However, it was the beginning of 1973, and many technical problems could not be solved when it came to making handheld game consoles like the two types above, such as LCD screens, power supplies, sound, and even the most low-tech housings.

Zhang Heng's plan for game consoles is online, and the handheld series will not be launched until the second generation of arcade machines fully occupies the market, which is about 75 years.

The first generation of arcade machines, due to the limitations of CPU, memory, and peripheral circuitry, could only design simple games.

By simple, the game should be short and concise, with only black and white graphics and no sound effects.

If players want to play a game with color and explosive sound, they should wait for the second generation of arcades.

No one can afford to play now!

At this time, a PROM capacity is only 12K, and it can't store a large program at all, of course, you can add another piece, but it's just such a pitiful capacity, and the purchase price of each piece is as high as 45 US dollars, which is still the purchase price of Daheng, and you can't get the goods without 60 US dollars on the market.

So in a way, the hateful Japanese still did some merit to computer and game console users all over the world, and without their entry, the price of memory really wouldn't have crashed in the mid-80s.

In the 90s, Wanwan people also rushed into this Red Sea, and the price war was even more tragic at that time.

Enthusiasts who have built computers from the late 90s to the early 21st century must have some impression of this scene: in the crowded computer city, 32M or 64M of memory is spread all over the glass counter like cabbage, and it is moved around by merchants and stir-fried.

Facing reality, Zhang Heng had no choice.

The game of ping pong is Mirovite's, it can't be used, it can't even be imitated, Atari dares to imitate on "PONG", then wait to be beaten, maybe this time it won't be Philips' turn.

So he opted for Tetris, which was short, and to the point.

This game program, in the previous life, as long as people who learned programming, basically programmed, at first using the C language, and later using C++ to call various function libraries, it is faster.

As a student of the Department of Microelectronics, Zhang Heng naturally does not just rewrite programs in C.

At that time, there was a course called "51 MCU", which included the experimental part of the computer, which accounted for a very large proportion, and each student had to build a system using a single-chip microcomputer at the end of the semester, and the teacher would score and record the admission score.

Some people have designed a "traffic signal command system", some people have designed a "piano simulation and score recording and automatic playback system", and some people have a big brain, they have designed a "dream recorder", and his system is called "using 51 microcontrollers and LED panels to design a Tetris simulator".

In short, it is to use the 51 microcontroller as the motherboard and the LED LED panel as the screen to simulate the Tetris game.

It worked out well, and at least the breadboard and keyboard circuit were kept as a teaching demonstration for the next class of students.

As for that so-called dream recorder...... The sensors purchased by the students at their own expense were confiscated by the laboratory teachers!

It's good to look at the sensor, and I finally gave it a passing grade.

Zhang Heng naturally won't just prepare this one game, ping pong can't be used, but another game based on this principle may be able to barely pass the level.

"Below, I have another game design idea that you can discuss. He took the four of them to the blackboard and picked up a chalk brush to make a few strokes.

"This is still ping pong!" Zhang Zhefeng blurted out, and then immediately covered his mouth.

"Don't be embarrassed, Zhefeng is right, it looks like I did draw a racket and a ball. Zhang Heng glanced back at him and said with a smile, "If I draw another white line on it, it will just turn the table tennis table down, but what if it is not a table tennis racket on it?"

He then drew several layers of stacked bricks on top of it and asked, "How would the game play in that case?"

"Squash!" Lin Wencan blurted out this time.

Fajin frowned and said: "Squash, it is almost no different from table tennis, it is likely that it will still be accused of plagiarism, maybe you have to change your thinking......"

After a few minutes, the four shook their heads in unison, indicating that they couldn't think of anything new to play other than squash.

"It seems that everyone was obedient and well-behaved when they were young. Zhang Heng smiled and said, "I'm different, I was ...... in the village when I was a child."

The words stopped abruptly, he suddenly came to his senses, and almost leaked his mouth, telling his childhood experience in the countryside in his previous life, fortunately, he stopped in time, anyway, Lantian is also a village.

"I often threw stones at the wall and tried to tear it down, but unfortunately it didn't work. Zhang Heng continued.

Several people listened quietly, but their eyes at the boss had a complicated meaning, as if they had thought of something else.

"I believe that not only children, but also many adults have similar impulses to destroy buildings, but in real life they can't do it. Zhang Heng didn't know that in the hearts of the employees, his head began to rise, and he said with high emotions.

"So, we can design a game where people can vent their desire to destroy for just one coin!"

"This game, I call it 'Arkanoidal'!" he wiped off a brick on the blackboard and drew a ping-pong ball in its place.

Everyone met silently, Fajin took the lead, including He Jie, and the five people applauded warmly.

"I'm sure this game will be a big hit. Fakin leaned in and whispered, "Boss, I really want to open your head and see how many good things are hidden inside." ”

For his first half of the sentence, Zhang Heng happily accepted, the game of Arkanoid is indeed very popular, after Atari was launched on the video game console in the previous life, 160,000 copies of the game cartridge were sold in the first month.

And interestingly, the programmers who developed the game at the time were named Steve Jobs and Woz, the two founders of Apple later.

And the second half of Fakin's sentence...... Zhang Heng pretended to be frightened and pushed him away, and everyone burst into laughter.

When everyone was almost quiet, Fakin doubted: "Boss, there must be no problem with the playability of this design, but no matter how you look at it, this game is based on a ping pong game, and even half of it is exactly the same, I am worried that there will be legal risks at that time." ”

What he said made a lot of sense, and this was exactly what Zhang Heng was worried about.

Even if it is changed from a ball game to a single-player wall removal game, it is still essentially a racket to receive a serve.

It's really fucked up, table tennis is obviously an ordinary sport, but it was preemptively developed into a game by Ralph Henry Bell, and he monopolized the copyright all of a sudden.

Can I be the first to develop sports games such as football, basketball, etc.?

Zhang Heng frowned and pondered, countless thoughts turned through his mind, but he couldn't find a solution for a while.

"Boss?" Zhang Zhefeng whispered.

"Zhefeng, if you have a suggestion, just say it. Zhang Heng said with a smile.

"Since the mode of table tennis is not good, can you change to other balls, such as basketball?" He is still a little unconfident, "I like to play basketball, and sometimes I throw the ball hard against the wall......"

"Okay!" Zhang Hengda shouted, stepped forward and patted him on the shoulder, and said with a smile, "Next time we will play together." ”

Back at the blackboard, he wiped off the racket and ball underneath and drew a pair of slightly open hands, holding a ball several times larger.

"Just change it like this, the hand doesn't have to be too realistic, you can recognize it as a hand, the ball is not too big, it's 4 or 5 times bigger than a table tennis ball, and the game speed needs to be set slower, otherwise it will be very difficult. ”

Considering the efficiency of the CPU at this point, the game screen simply can't show much detail.

"Boss, there may still be a problem here. Lu Yun immediately raised a new question, after switching to hand-to-hand basketball, the rebound mode is not logical.

The most interesting part of this game is the uncertainty of the direction of the rebound after the collision of the ping pong ball, and in reality, the hand cannot achieve a linear rebound at all.

Everyone was dumbfounded, looking at the blackboard depressedly, frowning and pondering.

Next, everyone discussed similar ball games, baseball, tennis, etc., and finally found that this game is really only possible with table tennis.

"Maybe there is time to spare, when Daheng's arcade becomes popular, Mirohua may have become my bag.

Having said that, even if there has been a legal action before, you can find a way to delay it until the end of March.

Neo, I'm sorry, I'll give you a hand when you lose the movie. ”

In his heart, he said sorry to the playboy who had a bad impression, and Zhang Heng quickly made a decision: "Then let's choose table tennis, and the legal risk company will find a way to solve it." ”

Fakin and others should go down and start work immediately.

"When the orb destroys the bricks, it's a good idea to add an effect sound, so that the player should be more happy, so you can find out which sound is more appropriate. Before leaving, Zhang Heng deliberately added another sentence.
