Scholars in the courtyard

In the afternoon, Yang Xiaotao drove to the Seventh Machinery Department.

In front of the gate, Yang Xiaotao saw Han Sanfeng smoking a cigarette and waiting, so he quickly stopped the car and got out.

The last time I came here, I thought the gate of the Seventh Machinery Department was a bit shabby. It was bare and bare, and the sign was made of wood. It was down several notches compared to the First Machinery Department.

When Yang Xiaotao got out of the car and saw Han Sanfeng coming over, he immediately approached him with a smile and said, "Uncle Han, you are here to wait for me."

Han Sanfeng also laughed, "No, I was called out by the chief, so I'm waiting here to greet the big shot."

"Don't dare, don't dare, I'm not a big shot."

Yang Xiaotao waved his hand quickly, then asked Han Sanfeng to get in the car and drove inside.

When I came here last time, I knew that the Seventh Machine Department was very powerful. If I had to walk, it would probably take ten minutes to reach the destination.

The two of them took the car and walked inside, chatting by the way, "Uncle Han, have you been very busy recently?"

"I'm busy. I won't be busy any day."

"You heard about my coming this time, right?"

"I know, the chief said, ahem, we don't care, we also need to work on the calculator."

Han Sanfeng almost let it slip, but seeing that Yang Xiaotao's expression didn't change much, he immediately reacted.

In fact, he feels that there is no need to engage in these fictitious things. If you have it, you have it, and if you don’t have it, you don’t have it.

With Yang Xiaotao's intelligence, he might have figured it out a long time ago.

Anyway, he felt very awkward about this kind of swollen face and pretending to be fat.

But there is nothing he can do. If the leader says something, he has to listen.

What's more, this 50,000 yuan is said to be research funding for them.

Ahem

The calculator is with them, so it has something to do with them.

"Uncle Han, you have to help me this time and pick a few capable people for me."

Yang Xiaotao ignored Han Sanfeng's thoughts and asked, "The two calculations you helped me calculate last time are good. Do you think you can help me run them?"

"Last time? Are you talking about Xiao Wang and Xiao Liu?"

"I don't remember, but they both felt pretty good."

Yang Xiaotao forgot their names, but last time he was able to calculate several combinations of alloys, and then asked the Alloy Research Institute to make them. This shows that the other party has real talent and knowledge.

When Han Sanfeng heard what Yang Xiaotao said, he was also thinking about it. Mr. Wang had told him before that it would be given to two people, but he would decide who to give it to.

At this moment, Yang Xiaotao took the initiative to mention the two of them, which made him a little embarrassed.

Because these two people, although young, have flexible minds and solid mathematical skills, they are talents he is optimistic about.

If this was given to Yang Xiaotao, I would feel a little reluctant to part with it.

But then I thought about it, the project itself is here, and the two of them did not leave the Seventh Machinery Department, they just helped set up a project with multiple identities.

"You are good at picking. Wang Kun and Liu Yongqiang are considered young heroes among us. They are very talented in mathematics."

"Haha, of course, the person I like is definitely not bad."

"Well, it's all with us anyway, so it doesn't matter if I let you use it."

"Then it's settled."

"As long as you can convince them."

"good!"

The two of them talked and then came to the front of the office building.

Han Sanfeng then got out of the car and led Yang Xiaotao to the office.

In the room, Mr. Wang did not show a cold face when he saw Yang Xiaotao, but came forward enthusiastically, "Welcome. Our conditions are simple, so don't worry about it."

"This is a place full of talents and outstanding people. If it is considered simple, our machinery factory will just collect scraps."

"I really like your nonsense."

Mr. Wang patted Yang Xiaotao's arm and said, and the two looked at each other and smiled.

"Okay, let's get down to business!"

"You should have discussed this matter with Lao Han on the way!"

Yang Xiaotao nodded, "I want two people to help, and Director Han has agreed."

"Well! Now that we have agreed, let me also say that since we want to do it, we must do it for success."

Mr. Wang looked at Yang Xiaotao and Han Sanfeng, "I don't mean using your money, but using our people and machines. It feels like working for you or working for us."

"This money and this machine are all the property of the country."

"It's just used by us, so we have to be worthy of the country and the people."

Yang Xiaotao nodded, "Don't worry, we have to do a good job."

Han Sanfeng also nodded, "We all understand what the chief said. We are all here for the same goal."

Mr. Wang nodded, "I have said what needs to be said, and it is up to you to do what needs to be done."

"Do it well."

Both nodded.

Then Yang Xiaotao took out the written report. Mr. Wang read it personally and then handed it to Han Sanfeng. After reading it, the other party felt that there was no problem, so he signed the report and used his seal.

Yang Xiaotao also signed on behalf of the machinery factory and stamped it with the machinery factory's seal.

There are two copies, and Yang Xiaotao and Mr. Wang each keep one copy. This cooperation is considered completed.

The report pointed out that the Machinery Factory cooperated with the Seventh Machinery Department to establish a ‘calculator research group’.

It stipulates that the Seventh Machinery Department is responsible for providing personnel, materials, machines, etc., including but not limited to.

Machinery factories must provide the funds required for research in accordance with regulations.

Each month is fixed at 50,000 yuan.

until the project research is successful.

The report also stipulates that the ownership of the research belongs to the machinery factory, and the Seventh Machinery Department only has the right to use it.

In addition, Yang Xiaotao's identity as the person in charge was also clarified. As for the team members, Wang Kun and Liu Yongqiang were temporarily included.

"Director Han, take him to have a look and announce it by the way!"

After Wang Lao settled the project, he sent Yang Xiaotao away.

The two left the office and then visited the workplace under the guidance of Han Sanfeng.

The workplace of the future calculator is in Han Sanfeng's Computer Research Center.

Han Sanfeng brought Yang Xiaotao in and saw many people walking around. They all had a common feature, that is, they had a blue clip on their hands, and everyone had their own goals and walked very clearly.

Even if they met Han Sanfeng, they only stopped for a while and called the director, and continued to be busy after saying hello.

After walking for a while, the two went down the stairs. Yang Xiaotao felt that they should be underground. There was a vibration sound of machines around.

"This is our work area."

Han Sanfeng pointed to a long row of houses inside. At first glance, it felt like a workshop, very empty, with rows of iron cabinets placed on it.

Yang Xiaotao understood that this was the place to study computers.

"Is it cool?"

Han Sanfeng walked in front and laughed, Yang Xiaotao nodded.

"How many air conditioners have you installed?"

Han Sanfeng held up two fingers, Yang Xiaotao guessed that it must not be two, so he whispered, "Twenty?"

Han Sanfeng shook his head, "Two hundred!"

"These two hundred are underground, this is just one floor, there are two floors below."

"Oh! So big!"

"This is just the initial stage, and two more floors will be dug out later."

Yang Xiaotao nodded, "So many machines are turned on at the same time, it must use a lot of electricity."

"Yes, the power consumption is really high, the daily maintenance is a large number, if there is an emergency, the power consumption will be even higher."

Han Sanfeng introduced, Yang Xiaotao nodded in response, while looking at the equipment next to him.

After walking for a while, Yang Xiaotao asked, "Uncle Han, this is a transistor, right?"

Han Sanfeng paused, then nodded, "Yes, this is a transistor computer."

Then he looked at Yang Xiaotao again, "Last time you said that transistors can only be regarded as a transition, and integrated circuits are the mainstream of development."

"I have the same opinion on this."

"The third underground floor is where we study. We are going to study integrated circuits. Your calculator also uses integrated circuits, right?"

"Yes, but the requirements for calculators are simpler and not too complicated."

"I know, simple addition, subtraction, multiplication and division, right?"

Yang Xiaotao nodded, then asked about the development of integrated circuits.

Han Sanfeng pondered for a moment, thinking that Yang Xiaotao was also the person in charge of the project, and some things would be known sooner or later.

"We are researching integrated circuits. Although the progress is slow, we can still make simple circuits."

"What about the display screen?"

"You mean the display device?"

"Yes, can you make it? It would be best if it is liquid crystal."

"Liquid crystal?"

Han Sanfeng smiled bitterly, "Of course we know that liquid crystal is the best, but we have made many requests to the local authorities, but no one has been able to research liquid crystal."

"Then how do you plan to make the display device?"

"We haven't thought about it yet, but we can't make do with it."

Han Sanfeng said helplessly, and then the topic shifted to the calculator, "The calculator you are talking about should be a simple small computing device."

Yang Xiaotao nodded, "Yes, it doesn't need too many functions, just addition, subtraction, multiplication and division. There is no need for storage, so a simple circuit board will do."

"Well! That's much easier."

Han Sanfeng heard Yang Xiaotao say this, and suddenly felt that this calculator was quite interesting, and she became interested in it.

Of course, it looks simpler than a computer, but it is also relative.

It's not easy to make it.

At least I don't have to think about it in the near future.

As the two walked, Yang Xiaotao asked about various situations. Some of his knowledge only existed in his memory, so his specific knowledge was definitely not as good as Han Sanfeng's.

Discussing with professionals would have a different effect.

As long as you raise doubts, the other party can always think of a solution, even if it is not suitable, they can provide reference opinions.

"Uncle Han, you said that the calculator does not have an LCD screen, what is the best replacement?"

"This is simple, you can use the TV screen method, anyway, they all use circuit boards, maybe it will work if you try it."

Yang Xiaotao thought of the TV at home after hearing this.

He also thought of some things in his previous life.

Every time in the middle of the night or early in the morning, you will see a black and white test picture, which is round and square, and there is a timer below. At that time, every time you open it, you hope that time will go faster and the picture will come out earlier.

The projection of this kind of TV is actually controlled by a circuit board.

There are various components on the circuit board, such as transistors and capacitors. They are welded together one by one, and a circuit board is formed after power is turned on.

Then, through a unique control method, the image can be expressed on the screen.

However, the welding technology at that time was very crude, and it was inevitable that parts would become loose.

Yang Xiaotao remembered that when the TV at home was playing, the screen would be distorted from time to time. At that time, the old man would walk to the TV and tap the back cover twice, and it would basically be fixed.

At that time, this method of tapping the back cover of the TV in various ways became a necessary skill for almost everyone.

This shows that this path is feasible.

"Then let's give it a try."

"By the way, how do you think the processing device should be made?"

"This is not difficult. What you want is convenience and no storage. So this is different from the binary system of computers. You can use the ten-digit system, which is also convenient for input and display."

Yang Xiaotao became more and more excited as he listened, and with Han Sanfeng's explanation, he felt that the direction of the research was becoming clearer and clearer.

"Uncle Han, why don't you take the lead in this work."

Han Sanfeng was talking about his own views, and suddenly heard Yang Xiaotao say this, and was stunned.

Seeing Yang Xiaotao's serious look, he waved his hand quickly, "Don't, it's not that I don't help you, it's really that I have a lot of things to do here, and I don't have the energy."

"Don't spend too much energy, this way, anyway, it's here with you, you can come and see when you have time, and help out and give some ideas."

"Uncle Han, just consider it as a favor."

"This"

Han Sanfeng hesitated, not knowing whether to agree.

In fact, after learning the whole story from Mr. Wang, he felt a little uncomfortable.

Although it sounds good, the two sides will cooperate in research.

But when it comes to the real work, they are too busy to have the time and energy to work on this calculator.

This is obviously a scam.

Looking at Yang Xiaotao's sincere look, Han Sanfeng is not as thick-skinned as Mr. Wang after all, so he nodded gently, "Okay, I will take care of it when I have time."
