Due to the international blockade, the state decided that the 757 project should use its own integrated circuits.

The integrated circuits used in mainframes are different from others and have special requirements for speed, so it is necessary to use a high-speed integrated circuit called ECL.

At that time, ECL could not be produced in Huaxia, but was only in the stage of research and development and small-scale trial production. If this thing cannot be put in place, it will seriously affect the progress of the 757 mainframe computer, so Wang Suo came to Shanghai Metallurgical Institute for help. (The fish bubbles: the ECL integrated circuit, the key component of the 757 machine in the official history, was developed by the North 748 Factory, and the yield is extremely low.

Cao Changjiu took a ride, and he wanted to go with him, constantly emphasizing that it was the first time he went out or to Shanghai.

The king could not resist him, so he had to take him with him.

Although Wang Suo is old, he is still an old revolutionary, and his body is okay. On the train, Wang told Chang Chang about his studies in Shanghai.

"When I was 16 years old, I came to Shanghai Institute of Technology to work and study. It was during that period of time that I learned something, and then I transferred to Peking Institute of Technology to study electrical engineering, which can be regarded as entering the industry. When I think about that time, I really miss it. Wang Suo lit a cigarette, looked at Cao Changjiu's black hair, and then touched his own, and couldn't help but sigh in his heart.

Cao Changjiu hurriedly took out a match, wiped it skillfully, lit it for the king, and picked up one himself by the way.

Wang Suo really hadn't seen him like this, and smiled in surprise: "The young man is very skilled in business, isn't it good to smoke at a young age." ”

Cao Changjiu pinched the match: "When I was a child, I often lit a cigarette for my grandfather, but when my grandfather is gone, no one cares about me." He threw it out the window.

Poor boy, the king said. However, he couldn't help but ask again: "I'm still in school at your age!" If you want to, I know a few people, and there is no big problem in entering Tsinghua University and Peking University at your level. ”

Cao Changchang smiled and said: "Didn't you also work and study part-time back then, and besides, what university teaches now can be compared with what we do now? Diploma, you have said that you can enter the university if you know people, so what's the use of this thing? When I have money, I will run two schools by myself." ”

Wang was puzzled: "Why do you run two schools?"

Cao Changchang said seriously: "Send me two diplomas, one for others and one for fun." ”

Wang Suo couldn't cry or laugh, he had been with him for a long time, and he also knew that this kid was indispensable on the outside, and it didn't matter what he did, but in fact, he was very stubborn on the inside, and he recognized a truth and persevered to the end, and he was very assertive.

Maybe this is the old man, Wang thought to himself. So he didn't discuss this topic with Chang Jiu, and only talked about his previous experience, which made Chang Chang Ting stunned and speechless.

Wang is a native of Shandong, his family went bankrupt when he was young, and he was adrift at the age of 16.

Later, Wang Suo had contact with the Eighth Road, and used his identity to buy communication equipment many times and transport it to the liberated area. What was more unfortunate was that the first battery transportation was unsuccessful and was caught by the Kuomintang.

God blessed the good people, Wang Suo was rescued by the Eighth Road, and since then he has given up the superior white-collar life, devoted himself to the revolutionary torrent, and became a - the Eighth Road of Technology.

"The eight roads of technology are also the eight roads, why haven't you ever fought?" Cao Changjiu obviously found fault, ignoring the murderous eyes of the king.

"Because I have a more important task than fighting! Okay, let's not talk about it today, wash and sleep, and tomorrow I have business to do. At last, the king became angry and began to clear the field.

Cao Changjiu had no choice but to go to the bunk, looked at the dim scenery outside the window, and fell asleep in a daze.

——————————

After a continuous long-distance bus to sit down, no one was not tired, and when they arrived at the Shanghai Metallurgical Institute, it was already late at night, and the two of them directly found a guest house to stay.

Early the next morning, the two came to the metallurgical institute after breakfast. The leader of the Metallurgical Institute is an old friend of the Wangsuo, and as soon as the two met, they began to catch up, completely leaving Cao Changjiu aside.

Cao was bored listening to it for a long time, so he told the king that the smoke in the house was heavy and went out to breathe.

After coming out, he began to wander around for a long time, walking in the yard and looking around.

That's the way it is for the most advanced integrated circuit design institute in Huaxia, this house is all the same, like a military camp, and I have thought about it for a long time.

Suddenly, I found that I couldn't find my way back, and this house was the same.

There was no way, Cao Changjiu had to look at the house by house, hoping to see the king's inside.

Chang was looking through the window, when suddenly a shout came from inside the room, "Who's out there? ”

I was scared for a long time, and I almost fell on my head.

The door slammed open, and a big man rushed out, and when he saw that it was a child, he was so happy that he shouted into the room: "I thought it was a class enemy who came to steal technology, and it became more and more a little child." There was also a burst of laughter in the room.

Cao Changjiu's face was flushed, and he said angrily: "What are you shouting, what broken technology is worth stealing from others, I'm just looking for someone." ”

The big man didn't think he was angry, but pulled Cao Chang's hand and said, "Don't mind, I'm just talking loudly." You're looking for someone, who's looking for someone, come in and say. ”

Cao Chang glanced at him and followed him into the house.

There was no furniture in the room, just a few drawing boards and chairs, and piles of drawings in the corners. The three of them sat at a large table and pointed at a large coordinate network map.

Cao Changjiu's eyes were sharp, looking at the picture and feeling so familiar, he took a closer look, and the suspicion in his heart was confirmed, but he didn't speak.

The big man pulled a stool for Chang Chang to sit down and brought him a cup of tea. Say thank you for a long time.

The big man saw that he was more interested in the drawings on the table, so he coughed lightly: "Kid, who are you looking for?" ”

Cao Changjiu came back to his senses and told him about his situation.

The four people in the room all chuckled when they heard this, and the big man said, "It is true that people outside are easy to get lost, but it is far away from you, the director's office is in front, and we are the westernmost here." Well, we're just going to see the director, you sit here for a while, we'll pack up our things, and we'll take you there. ”

Cao Changchang said: "You guys are doing integrated circuit design here." ”

A thin man wondered, "How do you know?"

Cao Changchang smiled: "I saw your network diagram, and the drawing is really good." ”

The big man said, "Yes, it just so happens that we just finished the design today, and we are in a good mood, otherwise you would be in trouble today." We are a confidential place here, and idlers are not allowed to enter. ”

Cao Changchang smiled: "What is there to keep secret, isn't it just an ordinary ALU unit!"

As soon as these words came out, the four people of the metallurgical institute were shocked, they didn't expect that the young man who crashed into the door could actually see the design on the drawings at a glance.

To the average person, a network diagram is nothing more than lines and patterns. So the big man let Cao Changchang look at it with confidence, who knew that Cao Changjiu's words were amazing.

The big man said, "Little one, what the hell are you doing, we have only just restored this part, how do you know it?" ”

Cao Changchang said: "It's unfortunate that I have done things, and these calculation logics are similar, basically the same, of course I know." ”

The big man and the other three looked at each other and asked, "You've ever made a microprocessor before?"

Cao Changjiu shook his head: "No, I make mainframe computers, but I have this idea, integrate the entire computer on a semiconductor chip, and I have also designed some logic by myself." I just looked at your picture and I felt familiar, and when I asked, it was true. ”

The big man was a little surprised: "You're making mainframe computers, are you kidding?"

Cao Changjiu was very unhappy: "If you don't believe that you will go to the director with me, then you will know?"

"Okay, let's go together!"

It would be easy for someone to lead the way, and Cao Changjiu and the four of them soon came to the director's office with the drawings.

When the king saw that he had come over for a long time, he was displeased and said, "Where have you been? ”

Cao Changjiu said embarrassedly: "I walked far just now, and I couldn't find my way back." ”

The big ones took the drawings and reported to the director.

"Fortunately, Director Mei is his own person, otherwise you wouldn't be a joke and have no rules. "The royal house is still educating for a long time.

Director Mei listened to the big man's report, nodded incessantly, and finally said to Wang: "Old Wang, your subordinates are really full of talents, even such a small disciple is so capable!"

Wang Suo smiled: "Where, the little guy only knows how to mess around, he doesn't have any big skills, only a little clever, hehe." ”

Director Mei: "You are modest again, but my people are not bad, let me introduce, this is a four-person team of our institute, which is now doing the work of copying foreign microprocessors, and has now successfully restored the ALU (Logic Computing Unit) design." ”

Wang said: "That's really amazing, really young and promising, to be able to imitate foreign microprocessors to fill the domestic gap." Lao Mei, your subordinates are all elite soldiers. ”

Director Mei said: "It's still not as good as you, tell you seriously, did you do this work a long time ago, and you didn't talk to us, it was too lacking in the spirit of mutual assistance of revolutionary comrades." ”

The king was puzzled: "What is this, what are you talking about?" ”

Director Mei smiled: "You just recruit it, you still hide it, the four of them told me, this comrade has designed a microprocessor, isn't it, Comrade Xiaocao, haha." ”

Wang looked at Cao Changjiu suspiciously, and Cao Changjiu said weakly: "I just did a little preliminary design by myself before, and there is no result. ”

Director Mei: "You did it yourself, that's good, then let's have more exchanges." ”

Wang said: "For a long time, I didn't expect you to have this ability." ”

Cao Changjiu: "It's purely a personal hobby, a hobby. ”

Director Mei: "Then a few of you will learn from Comrade Xiao Cao, Lao Wang, let's also take a look at what you want." ”

Wang Suo: "Well, Lao Mei, this matter still needs to be grasped, the country is in urgent need now." ”

Mei Suo smiled bitterly: "You don't know how difficult it is to make this thing, don't say that only one out of hundreds can be used, and it is also unstable, there are always some inexplicable problems, we are now organizing manpower to tackle key problems, hoping to complete the task in time." ”

Wang Suo also felt that there was no way, so he had to say, "Let's go, let's go and have a look first." By the way, for a long time, don't run around, just wait for me here. ”

Mei Suo hurriedly explained: "You four, take good care of Comrade Xiao Cao, and leave it to you." ”
