But Gao Hong, this little girl, is a little unready, she plays a mess, and she goes out to the wild every day after school, and her homework is naturally miserable. Cao Changjiu is funny every time she looks at her homework scratching her ears and cheeks, and she always likes to give a point or two beside her. Gao Hong is humiliated by it every time, and she feels that her eldest sister's face is dull, and she is naturally a real person PK under her annoyance.

Cao Changchang is not afraid, he always rebels, but he is weak and weak, and he ends up doing homework on behalf of Gaohong. Of course, the price is that small snacks are constantly available and open. Cao Changjiu likes this, which makes him feel the warmth of family.

As time went by, Gao Tuan also discovered a long-term abnormality. It's incredible that a half-sized child can do junior high school homework.

But every time Gao Tuan asked Cao Changjiu, he always avoided answering, and when he was in a hurry, he talked nonsense, saying that he read books by himself. Although Gao Tuan was not satisfied, he was not worried about his cultural problems.

Although Cao Changjiu succeeded in not entering primary school reconstruction, it also brought a new problem, that is, a lot of boring time did not know how to solve it.

In that era, that kind of life made Cao Changjiu unable to arouse much interest in children's entertainment activities, and there were no books to read, so he could only dream in a daze.

Games are human nature, and the only thing in Cao Changchang's dream is video games. But how can there be such a thing in 77 years of China, even in the world, this thing is rare. Cao Changjiu can only think about it when he is bored, and then how YY can get the video game in his dream to talk about it now.

Cao Changchang also thought of several plans, but the feasibility can be said to be no, and the only thing he can count on is to do it himself.

However, video games are a system project, an extension of the essence of human technology, and tall buildings will not rise out of thin air.

In this era, there was nothing, no hardware, no software, not even the personal computer (PC) had not yet been invented. This is especially true in China, the fastest computer in the country is only a million times per second, and it is estimated that it is still a state secret equipment, how can a little child come into contact with it?

There are only two ways to play video games, one is to wait patiently for more than ten or twenty years, others will definitely make it, but by the time the donkey year and horse month are definitely cold. The second method is a bit difficult, you can make a set of systems by yourself, even microprocessors, motherboards, peripherals, operating systems, etc., etc., although it sounds a little scary, but Cao Chang has been dominated by the strong and incredible desire to pass the time, everything is achievable, after all, in his dreams he is doing this.

In that strange dream, Cao Changjiu worked as a compiler in a wholly foreign-owned company, a very alternative electronic engineer, who usually did not interact with anyone, but just worked every day, tinkered with his own bizarre electronic devices, either studied mathematics (a very strange hobby), or played crazy games, until he was still single in his thirties. The family is surrounded by four walls, not poor, but he plays audio, high-fidelity equipment is placed in a rack, it can be said that in addition to a bed in the house, the whole small laboratory, this kind of life Cao has long been accustomed to.

Cao thought about it for a long time and felt that there was hope for success, anyway, there was no shortage of time for him, anyway, it was just waiting, and it was good to do something to pass the time. Although I also have the experience of making my own system in my dreams, how can it be compared with the present, and I don't know the principle of hair.

Cao Changjiu then started the first step of work, drawing the system engineering diagram, making some architectural ideas, and getting the compilation algorithm, because there was no design tool, he could only draw the circuit grid diagram by hand.

From the design to the manufacture of a computer, there are many disciplines involved, from mathematical logic to electronic circuits, which are incomparably complex. Thanks to Cao Changjiu's dream skills and unexplained memory, he came up with a theoretical model of numerical calculation logic step by step, and it took a lot of effort to convert mathematical logic into electronic circuits.

In his dreams, the conversion work was done by electronic computers, and Cao Changjiu only knew the principle, but was not proficient in it, and it was of course laborious to do it manually. It's like a student in the Red Age could open square roots by hand, but absolutely no one would make it a profession.

In Gao Tuan's house, Cao Changjiu spent most of his time in a daze, drawing grid diagrams, and making circuits.

Sometimes Gao Hong lay on the edge of the table and watched Cao Changjiu write and draw there, so he asked, "Brother, aren't you tired of painting these things here every day? What are these things? One line on the left and one line on the right, like a spider's web." ”

Cao Changchang smiled: "This is a household appliance in the future, you must use it every day."

"Is it a flashlight? It's not like it, hey, little brother, why did you fall, wake up. Dad, Xiao Jiujiu fainted!"

The first work of a long time is an adder, a very simple thing, as long as there is a material, it is good to connect it with a wire. I've been impressed by this thing for a long time.,This is what I did in my dream of doing an electronic experiment class in college.。 He didn't listen to the class, but it took two hours to complete the calculation circuits of binary, quintal, octal, decimal and so on, but the process was too exciting, so he deeply imprinted his mind.

This toy-grade calculator isn't much of a use, but it's enough to be amazed that at least you don't have to do your math homework by hand.

I persuaded her many times for a long time not to listen, so I simply sent her.

With nothing to do, Cao Changjiu is either immersed in his own world every day, or he just sneaks into the barracks to hang out. The artillery regiment has a lot of equipment, and the content of communications and science and technology is relatively high compared with other units. Men are usually interested in some sophisticated weapons, and cannons are Cao Changjiu's favorite.

Although the people are small, Cao Changchang is still very popular every time he goes to the Gao Tuan army and fights those who are soldiers.

The GIs still liked him very much when they were not training, and sometimes the GIs practiced calculating ballistic data there, and they couldn't come up with a result for a long time, and Cao Changchang was impatient to see it, so he would casually report a number, which became the answer every time
