At that time, except for professionals, how could they have access to computers? Therefore, I have been interested for a long time, from the origin of the computer to the current development, the role of social productivity, etc., and so on for two hours, the whole Secretary Hu is unable to find the north.

“...... Therefore, this is another technological revolution after the industrial revolution, China missed the last revolution, although under the leadership of the great leader to catch up, finally made some achievements, but there is still a distance from the Western powers. So what to do, we have to wait for the opportunity, what opportunity? The opportunity of the technological revolution! So that everyone can be on the same starting line. ”

"According to what you say, China has now developed at the same time as the West?" Secretary Hu was puzzled.

"No, but we have finally caught up with this technological revolution, although due to the gap in the industrial base, our electronics industry and the West have a gap, but I firmly believe that as long as China's national policy is formulated, it will be able to lead the world, and the Chinese people do not lack wisdom!"

"Oh, as far as I know, computers are very expensive, I remember what model of small computer imported from Japan cost 500,000 yuan, and it was very expensive. In China, only large factories can use it, and it is still the state's money. I think it will take at least 50 years for this thing to be fully popularized, how can it be as fast as you say. ”

"Well, that's a good question, but there are price barriers due to the limitations of today's technology. But that was the mainframe era, and the trend now is miniaturization. Have you ever heard of integrated circuits? Haven't you ever heard of a semiconductor, right? Just know, a computer can be done on a semiconductor, and it's not cheap if it's the size of a fingernail?"

Although Secretary Hu nodded blankly, his eyes were obviously unbelieving.

"Don't believe it? The US imperialists have already made it as early as '71! If you think about it, a computer can be bought for 10 yuan, and all the electric motors in the country are controlled by computers, which can save tens of billions of dollars in electricity bills a year. The steel mill can use a computer to automatically control the furnace temperature and forming, and the mechanical manufacturing can be added to the computer to become a CNC machine tool. For example, in the case of medicines, the molecular structure of a new drug can be automatically designed by a computer, and its properties can be known without manufacturing. There is also telecommunications, our telecom exchange is still mechanically vertical and horizontal, hehe, it can only accommodate dozens of telephones, and it has to be manually transferred, and it is backward. As long as the computer is used for program control, hum, all the automatic thousands of telephones are automatically connected, and all people have to do is sweep the floor in the computer room and drink water!"

"Okay, okay, what is there to shake before the true God. "Marx is on top, I hope what this kid said is true, Secretary Hu has completely lost his temper, interrupted the long time in the blind breaking, fortunately he has arrived at the Institute of Computing Technology.

Chang Chang followed Secretary Hu out of the car and came to an office.

Secretary Hu talked to an old man with silver hair for a few words, and then pointed at Cao Changjiu.

The two of them spoke in very low voices, and Cao Changjiu was puzzled, so he had to sit there and look around.

The room was very large, and there were drawing shelves in half of the place, and several people were concentrating on drawing something, Cao Changjiu stood up and wanted to take a look, but was pulled by Secretary Hu.

"It's Professor Wang. ”

"Hello Professor Wang, you will be my future teacher. Cao Changjiu bowed to the old man, recked in the influence of his dreams, and he always respected the old science and technology workers.

"Don't dare, don't dare, you're fine. The old man hurriedly helped him, "There is a precedence in asking questions, there is a specialization in the art industry, and everyone learns from each other." The old man glanced at Secretary Hu again, "Since it was introduced by Duke D, let's talk?"

Secretary Hu said: "It's okay, Xiao Changjiu will be handed over to you, the two of you will communicate first, I will come back tomorrow, I still have some things now, don't bother." ”

"You're busy, you're busy. After sending Secretary Hu away, Professor Wang pushed his glasses and said to Chang Chang: "Sit here, I heard Secretary Hu say that you made a calculator, can you take a look?"

"I'm sorry, I didn't bring anything. "It's a long embarrassment.

"Oh, it's okay, just talk about it. ”

"Then I'll just say it's like this......" He explained the structure and circuit implementation of the calculator for a long time, and drew a few drawings.

Professor Wang listened to Daqi, and listened to the structure and pattern that he had said for a long time, and he couldn't help but believe that this was something that only a professional engineer could understand, but he said it from the mouth of a child, and he really didn't accept the old man.

Professor Wang wiped his glasses, "Have you ever touched a computer before? According to what you said, the structure of the calculator is very formal, although the sparrow is small, it has all kinds of organs." ”

"I'm just reading books, I haven't seen a real guy yet, I'm just interested in this thing, and I always want to make my own, hehe. He smiled embarrassedly for a long time.

"Ah, that's amazing!" Professor Wang also smiled, "Do you want to see the real thing?"

Last time I saw the picture of Cray-1 (produced in '76, 100 million floating point calculations per second, the world's first at that time) made by the Americans, and I was really envious of it. Chang said excitedly.

"Hehe, we don't have that big guy, but we'll have it soon. Speaking of Cray-1, Professor Wang was not without regret, with a lonely expression on his face, and then replied, waving his hand and saying, "Come, follow me, I'll show you our own computer!"

followed Professor Wang to the computer room for a long time, and almost didn't cry out through the glass for a long time, a large cabinet with water, and a few terminals. The eye-catching is still the piles of messy stacks of perforated paper tapes.

As soon as Professor Wang pushed the door, a wave of loud noise came out of the door, which startled Chang Chang and trembled.

Professor Wang laughed, "Don't be afraid, it's the first time you come here, the computer room is a little louder." ”

“......”

It has completely subverted the long-standing values and world view, is this the computer room of the most advanced computer research institute in China? Although the noise level is not as high as the decibel level of the textile factory, it is absolutely piercing and torments people's nerves.

Professor Wang looked at the long-term **, thinking that he was shocked, and said proudly: "How about it, spectacular! A large-scale computer, millions of calculations per second, domestically produced, the whole country is the only one; 5 imitation PDP11 16-bit small computers, memory 256k, 500,000 times per second, but our treasure." ”
