Siheyuan: Start as a truck driver

In the conference room.

Under the surprised eyes of the researchers, Wang Weidong asked Yu Li to distribute the materials in front of them.

"Comrades, this is a drawing of a small computer that I personally designed. Please take a look at it first."

Hearing this, the researchers' eyes almost fell out of shock.

What a joke, the internal structure of a minicomputer is extremely complicated. Even though researchers like them have been studying it for so many years, they have only figured out some clues. Now the director of the factory actually says that he has developed the minicomputer.

However, seeing Wang Weidong's confident look, they suppressed their surprise and slowly opened the materials on the table.

The material is printed with ink.

There are not only texts but also drawings on it.

It is as thick as seventy or eighty pages.

The researchers have all studied minicomputers, and they just looked through it carefully and saw the clues.

Their expressions suddenly changed.

In this era, whether at home or abroad, research on minicomputers has just begun.

Many principles that may seem simple to later generations are theories that have never been discovered in this era.

For example, the internal structure of a minicomputer.

In the past, researchers were accustomed to treating minicomputers as an overall unified planning layout.

But in Wang Weidong's materials, the minicomputer is divided into several parts.

For example, motherboard, power supply, monitor CPU... Of course, even if the CPU of this era has developed graphics computing capabilities, it does not have a graphics card.

This design seems weird and cumbersome, but when the researchers thought about it carefully, they understood its benefits.

If minicomputers are considered as a whole, they must take all aspects into consideration when designing.

This will cause great difficulties in research work.

But now the small one is divided into several parts, so they only need to conduct special research on these parts each time.

For example, the motherboard of a minicomputer.

They can directly set up a minicomputer motherboard research group to conduct research on motherboards.

The motherboards designed and produced only need to be responsible for the corresponding standards.

There is also a power supply.

As long as the power supply can provide a stable current, it is sufficient to comply with the standard.

Of course the most important thing is the CPU.

Wang Weidong adopted an architecture that they had never seen before in the design drawings of the CPU.

This architecture is named 8086.

It is the standard numbering abbreviation for a general-purpose computer series and also identifies a set of general-purpose computer instructions.

The biggest advantage of this architecture is its portability.

The upgraded architecture is perfectly compatible with the old architecture.

This way.

Even if the CPU is updated, the original program can still run on the new CPU, so there is no need to redesign the program.

This can avoid a lot of waste of manpower and material resources.

At this time, a researcher raised a question.

"Director, in your design, the CPU is a computing software component. So what is this thing made of? Nowadays, many large laboratories and research institutes abroad have their computing equipment.

It's a large electronic tube."

"Yes, even the calculators inside the mainframes of our cable power stations are electronic tubes."

"Looking at your CPU, it can be placed in a small box, which shows that its area is very small. How can it meet the computing needs?"

As expected of a researcher who specializes in minicomputers, he could see the key point of the matter at a glance.

Whether it's the motherboard, power supply, or memory registers, they all work for the CPU.

Without a CPU, they're just a pile of scrap metal.

In this era, there was no concept of CPU, and there were no chips of later generations, only large electron tubes.

Wang Weidong asked Yu Li to take a blackboard and write and draw on it calmly.

"Comrades, you may know what an insulator is, just like the wood in our rubber shoes is made of collagen. You may also know what a non-insulator is, just like a wire, steel and steel can pass electricity easily."

"But there is another substance in this world called a semiconductor, which is a substance between a conductor and an insulator."

"For example, the TV sets and radios we commonly use have semiconductors inside them."

"It's just that the semiconductor inside plays a relatively weak role and only plays a role in signal conversion."

"Just imagine, if we use semiconductors to imitate electron tubes, what will be the effect?"

As soon as these words came out, the researchers were immediately stunned.

Semiconductor technology in this era is still very backward.

The semiconductors in radios are only the crudest ones.

It is simply impossible to use semiconductors to complete computing work.

Otherwise, the research laboratories opposite would not have spent a lot of money to build electron tubes.

"How is this possible? What are the semiconductors in the radio used for?"

"Yes, they can only handle simple signal welding machines and cannot complete tedious calculation tasks."

"The materials just mentioned are reasonable and well-founded, but when it comes to the key CPU part, it seems a bit fanciful. I think this factory director is a bit unrealistic."

Researcher Liu Chunyang was more sober than those researchers. He patted the table and said coldly: "Everyone, please stop arguing. Listen to what the director says."

Wang Weidong nodded at him and said with a smile: "The reason why the performance of the semiconductors in the radio is very weak is because the density on them is not enough. If we can increase the density, then the computing performance of those semiconductors can be greatly improved. Eventually.

It can achieve hundreds of millions, billions, or trillions of calculations per second.

"

When the words fell this time, the researchers remained silent and began to think thoughtfully.

Yes, semiconductors can be engraved infinitely. As long as dense circuit diagrams are engraved on them, miraculous effects can be produced. This has been confirmed by physicists.

Wang Weidong continued: "So the key to the problem is how to create high-speed computing semiconductors. I call this semiconductor a chip.

The next focus of our research institute is to study how to manufacture high-speed computing chips."

The results of scientific research are the results of countless failures. If someone knows the answer in advance, it will be much simpler.

The current domestic researchers are actually very capable. After hearing the concept of chips, they quickly understood the mystery.

Especially Professor Liu Chunyang.

He even came up with several plans in an instant.

Wang Weidong saw the researchers talking incessantly and nodded with satisfaction.

Even if these researchers can't study anything, they can get a complete set of CPU drawings from the system.

It won't be long before the chip will be born openly in the research laboratory.

"Okay, I now order our laboratory to set up a chip research team. I will be the team leader and Liu Chunyang will be the deputy team leader."

Under Wang Weidong's order, Lanhua Automobile Factory began chip research work.

The other side.

Xu Damao also began to carry out Wang Weidong's mission to find out what method he used to rescue Ban Ge from the Mediterranean Sea.

He first started with the Jia Zhang family.

Jia Zhang, an old woman, doesn't have much brains even though she usually chatters a lot.

Especially Xu Damao brought her a box of snacks.

Looking at the box of snacks, Jia Zhang couldn't close her mouth.

"Oh, Xu Damao, the sun really came out from the west today. After so long, you finally remembered me, old lady."

Before Xu Damao married Qin Jingru, he was very good to the Jia family.

After all, he had obtained Qin Jingru through illegal means. In order to gain Qin Jingru's support, Xu Damao had to vigorously win over the Jia family.

Especially since he is also a projectionist. Every time he goes to the countryside to show movies, he always gets some good stuff from the countryside.

If something is not yours, you won't feel bad if you give it away.

Peanuts, wheat, rice, pecans...delivered to Jia's house with great enthusiasm.

But since he married Qin Jingru, he seemed to have forgotten about the Jia family.

After hearing what Jia Zhang said, Xu Damao was not upset at all. He chuckled and said: "Jia Zhang, now that the deaf old lady is dead, you are the head of our courtyard. As a junior, it is reasonable for me to honor you.

As it should be.”

Hearing this, Mrs. Jia Zhang was so happy that she couldn't close her mouth from ear to ear.

In the past, in the courtyard house, the deaf old lady came first, then the first aunt, the second aunt, the third aunt, and finally it was his turn, Jia Zhang.

Now Xu Damao actually thinks that her status is higher than that of Auntie. Can she be unhappy?

"Oh, Xu Damao, your little mouth looks like honey. If I were to kill a pig, I would be so happy to have such a good mouth like you!"

Xu Damao took the opportunity to ask: "Ms. Jia Zhang, Shazhu is about to become your son-in-law, but he didn't give you any indication?"

Jia Zhang rolled her eyes: "Don't mention that fool Shazhu. Whenever I mention him, I get angry."

"What's the matter?" Xu Damao asked.

Mrs. Jia Zhang patted her thigh and said: "Si Zhu is such an idiot. He wants to go to my house. Qin Huairu and I agreed, but he didn't show any sign to my old lady at all. Just yesterday I asked Si Zhu

Go and buy a cash register for me, Silly Zhu actually said that he has no money in his hand, do you think this is ridiculous?"

When Xu Damao heard this, he called him a good guy in his heart.

Now a radio costs more than 180 yuan.

Silly Zhu has no job and eats and drinks from the Mediterranean. Where did he get the money to buy a radio for Jia Zhang?

Besides, even if Silly Zhu is rich.

He wouldn't buy it for Jia Zhang, and he didn't marry Jia Zhang, but Qin Huairu.

But Xu Damao is a smart man, and of course he will not refute Jia Zhang.

He clenched his fists and said, "Si Zhu is too shameless. You are Qin Huairu's mother. After Si Zhu marries Qin Huairu, you will be Si Zhu's mother.

Silly Zhu, as a son, should be filial to you.

Let alone a radio, even if it is a TV, Silly Zhu should immediately buy it and give it to you."

Xu Damao's words spoke to Jia Zhang's heart.

Jia Zhang said with a cold face: "That's right. Silly Zhu is nothing. If he hadn't rescued half of my family, I would never have agreed to Qin Huairu's marriage to him."

Hearing this, Xu Damao took the opportunity to ask: "Jia Zhang, please don't think I'm too worried. Silly Zhu is just a fool. Besides, he doesn't have a job now. How can he rescue Banggeng?"

Jia Zhang laughed: "You don't know this. Although Silly Zhu is not good, there is still the Mediterranean Sea."

"Mediterranean is only in the street office, and he has some connections and is not familiar with the people at the police station. How can he save her?"

Jia Zhang looked around and saw that Qin Huairu was not around. She lowered her voice and said: "Xu Damao, let me tell you something. You must not tell Qin Huairu. Qin Huairu does not allow me to tell people outside that I am here today."

I'm telling you because you brought snacks to my old lady.

You must not make things difficult for me."

Xu Damao patted his chest and said, "Aunt Jiajia, don't worry, I, Xu Damao, must be very strict with my mouth. When did you see me betraying others?"

Don't tell me yet.

Although Xu Damao had betrayed so many people, he did things very secretly, and even the residents in the courtyard did not know.

Naturally, Jia Zhang didn’t know either.

She said with confidence: "I heard from Qin Huairu that Mediterranean found a previous relationship with the deaf old lady. That person was a deputy director in the subdistrict office and had a good relationship with the comrades at the police station. He would definitely be able to bring good things to my family.

The joke will come back."

The deputy director of the sub-district office...Xu Damao frowned and thought for a while, but couldn't remember who he was.

He decided to tell Wang Weidong about this later.

This chapter is not finished yet, please click on the next page to continue reading the exciting content! At this time, Qin Huairu just walked in from outside.

She also carried a lot of vegetables and a lot of meat in her hands.

obviously.

Qin Huairu is about to get married to Shazhu, and he will definitely give her a lot of money as a bride price.

Seeing Xu Damao and Jia Zhang mumbling there, Qin Huairu's heart hung in his throat, and he rushed up quickly and asked, "What are you two talking about?"

Xu Damao waved his hand and said: "I didn't say anything, I was just discussing how much gift money should I give you when you marry Silly Zhu?"

As soon as these words came out, Qin Huairu stopped worrying about what had just happened and said excitedly: "Xu Damao, you are Qin Jingru's husband, and I am Qin Jingru's cousin. The relationship between the two of us is very close."

"Generally, neighbors in our compound get a gift of two yuan when they get married. For a relationship like ours, you have to get at least four yuan as a gift."

Xu Damao took a breath of cold air: "Qin Huairu's gift of 4 yuan, are you thinking too much? You must know that my monthly salary is only more than 40 yuan."

Qin Huairu curled her lips and said, "Xu Damao, don't be dissatisfied. If I hadn't introduced Qin Jingru to you, would you have a child now?"

She said this in a threatening tone: "If you don't want the child, I will go to your house in two days to persuade Qin Jingru to go to the hospital to abort the child."

Xu Damao's face suddenly turned livid.

His family is a single generation of three generations, so he is counting on the child in Qin Jingru's belly to continue the family line.

Now Qin Huairu actually uses that child to threaten herself, which is really abominable.

He sneered twice in his heart: OK, if you threaten me, then I will prevent you from getting married.

Xu Damao nodded towards Qin Huairu and said, "Okay, I will give you a gift of 4 yuan when the time comes."
