The rejuvenation of a great nation: from educated youth to national treasure scientist

Chapter 130 A world-class breakthrough at your fingertips

Wang Haoran asked tentatively, "Does Teacher Lin have any other important research topics on hand recently?"

Lin Yuanchao smiled bitterly and said, "There is one. I originally wanted to develop a more advanced microcomputer."

“It’s almost done now.”

"However, this topic actually doesn't have much significance anymore."

"I can devote myself to the project I am working on with you."

Lin Yuanchao also knew what Wang Haoran meant by asking this question.

Wang Haoran smiled and nodded, saying, "Thank you, Teacher Lin!"

"Cooperate with me, I will never let you suffer any loss!"

"Let's work together to make our domestically produced microcomputers catch up with the international advanced level!"

"I see you are good at integrated circuit design?"

Lin Yuanchao waved his hand and said, "In front of Comrade Haoran, I dare not say that I am good at integrated circuit design."

"The Pangu 1 CPU you designed is much more powerful than any CPU model I have ever designed."

"I don't have any other advantages, except that I am good at cooperation."

"If you need me to do something, I will cooperate with you and try to make it perfect."

Wang Haoran was quite satisfied with Lin Yuanchao's attitude.

He smiled and calmly chatted with Lin Yuanchao for a while about the technical details of the integrated circuit.

This is mainly to see what Lin Yuanchao's professional level is.

Lin Yuanchao is also a very smart person. He knows what Wang Haoran means by talking to him about this.

He also tried hard to express his own views.

In Wang Haoran's opinion, Lin Yuanchao's knowledge is a bit backward.

However, his learning ability and basic knowledge of microelectronics are still solid.

After chatting for a while, Wang Haoran said, "Teacher Lin, I'd like to let you develop the computer's memory. Is that okay with you?"

Memory chips are also an indispensable and important computer component.

The CPU performs read and write operations through the memory bus addressing.

If the memory is not large enough, it will limit the operation of the computer software.

Lin Yuanchao nodded and said, "I will definitely complete the task."

He didn't say anything like "I'll try it", but expressed his determination directly.

Wang Haoran smiled and said, "Our previous memory was directly soldered to the motherboard, right?"

Lin Yuanchao said: "Yes."

"Memory is critical and can break easily."

“If it’s broken, you have to weld it off before you can replace it.”

"I have been thinking about how to make memory more convenient and easy to use."

At this time, computer memory is in the form of small chips.

The memory is soldered directly to the motherboard.

This is not only inconvenient to install, but also more inconvenient to maintain.

Another thing is that its capacity is very small, and nowadays the memory is only a few KB.

In the past, memory sticks did not appear until the 80286 processor.

The so-called memory stick is actually memory chips soldered to a pre-designed printed circuit board.

There are memory slots on the computer motherboard. Simply insert the packaged memory stick into it and you can use it.

According to Wang Haoran's plan, the computer production line he is going to build will directly produce Pangu No. 80286 computers that are equivalent to the 3 processor in the future.

Then you have to take out the memory stick in advance.

Wang Haoran smiled and brought up the idea of ​​the memory stick: "Teacher Lin and I had the same idea."

"I do have an idea: we can make a designed printed circuit board, solder the memory chip directly to the circuit board, and then package it..."

As Wang Haoran spoke, he drew out his design ideas on a piece of paper with a pen.

The memory stick design he drew was called "Dual-Inline-Memory-Modules".

In fact, the earliest memory stick design was a "single in-line memory module".

That is, only one row of memory chips is arranged on a printed circuit board.

This can greatly expand memory capacity and run more complex software.

However, this design has many problems. For example, the gold fingers on both sides are interconnected, and the utilization rate is very poor.

Wang Haoran felt that since he was an entrepreneur and had a vast amount of resources in the biochip memory capsules, he might as well start higher.

Then just take out the DIMM memory stick.

When Wang Haoran told Lin Yuanchao about his idea, Lin Yuanchao suddenly understood.

He exclaimed: "What a genius design!"

Wang Haoran smiled and said, "I'll come up with the idea, Teacher Lin will perfect it, and then we can share the results. Is that okay with you?"

Lin Yuanchao hesitated for a moment and said, "Comrade Haoran, I am a little ashamed of this."

"Your design has already taken shape!"

"The results should belong to you alone."

Wang Haoran waved his hand and said, "Creativity is one thing, and implementing it is another."

“This also requires a lot of hard work and sweat.”

"Just do it boldly!"

"If this result is successful in the future, you will be able to obtain the title of academician."

Lin Yuanchao's heart skipped a beat.

As for the achievement of computer memory sticks, if it can be really achieved in the future, it will definitely be a major breakthrough.

There should be a high probability that he will get the title of academician with this breakthrough.

"Well, thank you, thank you Comrade Haoran." Lin Yuanchao said.

At this moment, his heart was filled with gratitude.

Lin Yuanchao thought: No wonder all the scientists who have worked with Wang Haoran have spoken well of him.

Wang Haoran is indeed very smart and selfless.

Wang Haoran smiled and said, “You’re welcome!”

"Teacher Lin, let's make it a deal, right?"

Lin Yuanchao quickly said, "Okay, okay! I'll get started preparing as soon as I get back."

Wang Haoran smiled and said, "It's better to prepare first. We will have a project meeting in two days. At that time, I will provide some ideas."

Lin Yuanchao was very nervous when he came, but was overjoyed when he left.

He also secretly made up his mind: he must work hard, only in this way can he repay Wang Haoran's kindness.

After seeing Lin Yuanchao off, Wang Haoran put the refrigerator production line project aside.

He decided to talk to all the main partners first. After the discussion, he would hold a meeting to formally assign tasks, and the computer production line project could begin.

Wang Haoran went to visit his father-in-law Xiao Renming.

In theory, the computer field is very different from Xiao Renming's radio major.

However, the Department of Radio Electronics is the predecessor of Peking University's School of Information Science and Technology.

This department has been involved in research in computer science and technology since the 50s.

In addition to radio, Xiao Renming's research also includes microelectronics.

When Wang Haoran rushed to Xiao Renming's office, He Yiming, the director of the Department of Computer Science and Technology of Peking University, happened to be talking to Xiao Renming.

After Xiao Renming was elected as a member of the academic department, his academic status rose rapidly.

Peking University’s formal computer technology department was only established last year.

He Yiming is considered the founding director of the department.

This newly established computer department is divided into two majors, one is computer software and the other is microelectronics.

Microelectronics is actually the research on chips.

He Yiming originally hoped to have Xiao Renming join the Computer Science Department to take charge.

In this way, if our department has an academician, it will have greater appeal.

However, the Radio Department would not let him go.

Xiao Renming himself was unwilling to go there.

He Yiming had no choice but to settle for the next best thing and see if he could ask Xiao Renming to teach a part-time course in the Computer Department.

He Yiming was very surprised when Wang Haoran came to visit him suddenly.

Because he suddenly thought: It would be nice if he could invite Wang Haoran to be an external teacher in the Computer Department and give a few classes to the students in the Computer Department.

"Comrade Haoran, nice to meet you!" After Xiao Renming introduced him, He Yiming quickly shook hands with Wang Haoran and said hello.

Wang Haoran responded with a smile, "Hello, Teacher He!"

"I heard that you have great accomplishments in programming. I was planning to visit you when I have time!"

He Yiming is a programming expert, and Wang Haoran has heard of his reputation.

He Yiming smiled and waved his hand: "Comrade Haoran, you are too polite. I only have a basic understanding of programming."

"However, our country is indeed in great need of talent in programming right now."

Wang Haoran said: "I have just applied for a research project on computer production lines, which involves software programming."

"I wonder if we can work together?"

Wang Haoran sent an invitation directly.

He Yiming rubbed his hands happily and said, "Of course!"

"Comrade Haoran, if you need anything, just tell me."

"Also, I have a request..."

He Yiming also invited Wang Haoran in person, hoping that he could teach a course to students of Peking University's Computer Science Department as an external teacher, for example, the chip-related textbook written by Wang Haoran himself.

Wang Haoran was a little embarrassed.

The main reason is that his scientific research tasks are quite heavy.

It is simply impossible to attend so many classes regularly every week.

Wang Haoran said: "Teacher He, I really hope to share my scientific research experience with my classmates."

"But I'm quite busy, and I'm worried that I won't be able to teach my classmates regularly."

“It would be OK if we held a related lecture once a week at irregular intervals.”

He Yiming was delighted: "It doesn't matter! The students will be very satisfied if you can give a lecture every week!"

Wang Haoran smiled and said, "Then it's settled."

"As for me, I hope to invite you to write our own Chinese operating system."

"This is also a huge project that requires the joint efforts of linguists, software engineers, and hardware engineers." He Yiming was also quite straightforward. He nodded happily and said, "No problem!"

"By the way, writing a Chinese operating system is also my dream."

“But this is a very difficult matter.”

"It won't happen overnight."

Wang Haoran smiled and said: "It is indeed very difficult, but as long as we work together, I believe we can succeed!"

"I wonder what programming language you use, Mr. He?"

He Yiming said: "I mainly use Basic, and I also know a little bit about ALGOL60 and FORTAN."

Programmers are a scarce resource these days.

It is even rarer to find a programmer who can master three programming languages ​​at once.

Wang Haoran began to discuss the issue of operating system writing with He Yiming.

He Yiming seemed to know a lot about operating systems. He even knew the 86-DOS operating system of Seattle Computer Products Company.

He Yiming was also shocked by Wang Haoran's knowledge in operating systems.

Because Wang Haoran can even break down the overall architecture of the operating system and explain it clearly.

Most importantly, what Wang Haoran said was very inspiring to He Yiming.

After chatting with Wang Haoran for more than an hour, He Yiming said excitedly: "Comrade Haoran, I was deeply touched by talking with you today."

"I am now full of confidence in developing a completely new computer disk operating system."

"Let's discuss it together some other day and see how to start preparing."

Wang Haoran smiled and nodded, saying, "Okay! Let's have a good chat some other day and try to get started as soon as possible."

"Teacher He, there are very few software talents in China!"

"It takes a group of programmers to work together to write such an operating system!"

He Yiming said: "I do know a few programming experts here."

He Yiming just mentioned a few names.

When Wang Haoran heard this, he realized that he actually knew these people.

The first person He Yiming introduced was Yan Yuanchao, a young genius from the Computer Institute. Later, he wrote the CCDOS operating system by himself, which was the first Chinese operating system in Longguo.

Of course, in the beginning, the CCDOS operating system was not very easy to use.

The second programming expert introduced by He Yiming is Ni Guangnan.

Ni Guangnan is a researcher at the Institute of Computer Science of the Chinese Academy of Sciences and a true computer expert.

Later, he founded a company with Liu Zhonglie.

In fact, Wang Haoran also thought of a few people.

For example, Wu Xiaojun, who developed the HHBIOS Chinese system, was just a financial employee, but he made a name for himself in the computer field based on his hobby.

For example, Qiu Bojun, who was later known as the number one programmer in Longguo, is only a 15-year-old boy now.

But Qiu Bojun was already famous for his extreme intelligence. The following year, the 16-year-old Qiu Bojun was admitted to the information system major of the National University of Defense Technology.

Wang Haoran was thinking about whether he should discover these two people in advance and bring them to Beijing Institute of Technology to do scientific research with him.

After He Yiming left, Xiao Renming smiled and said, "Haoran, you are going to study computers to death."

"However, I don't think I can participate this time because my major is not suitable."

Wang Haoran smiled and said, "Dad, don't you also study microelectronics?"

"You can certainly continue to play an important role in this subject of mine."

"I am going to assign you an important task."

Xiao Renming said: "I have only a rough understanding of microelectronics. Today's integrated circuits are a bit too complicated."

“I personally feel like I can’t quite figure it out.”

Wang Haoran said, "It's okay. Let's study it together. You will definitely find that researching computer hardware is not that difficult."

The task that Wang Haoran planned to assign to Xiao Renming was the research task of mechanical hard drives.

Mechanical hard disk is an important component of computer.

It is a computer data storage medium. The software and operating system installed on the computer are all on the hard disk.

However, the technology of today's mechanical hard drives is quite poor.

The best technology for today's mechanical hard drives is thin-film head technology.

This technology was invented by IBM and can significantly reduce the distance between the head and the disk, making it possible to further reduce the size of the hard disk, increase its capacity and improve the reading and writing speed.

Hard disks using thin-film head technology can have a storage capacity of up to 571MB.

Wang Haoran thought: The technological development of mechanical hard drives should continue to move forward steadily.

First, develop the thin-film magnetic head technology, and then in two years develop the giant magnetoresistive magnetic head technology. In this way, Longguo can continue to lead in hard disk technology.

This giant magnetoresistance technology is a Nobel Prize-level invention.

The two physicists who invented giant magnetoresistance technology won the Nobel Prize!
Although Wang Haoran doesn't care about the Nobel Prize, he cares about keeping the technology firmly in his own hands.

For example, the thin-film magnetic head technology, according to the trajectory of historical development, would have been invented by IBM in mid-1979.

Now Wang Haoran doesn't mind stealing this technology first.

Wang Haoran began to discuss the hard drive with Xiao Renming.

What he said was still very clever. Through discussion guidance, he made Xiao Renming develop a strong interest in mechanical hard disk, an important component of computers.

Actually, in China today, there are really not many professionals in the field of mechanical hard drives.

Currently, most of the mechanical hard disks used in China are imported from abroad.

Moreover, most of these hard drives are very large, with the smallest one being as big as a cabinet.

There are also miniaturized hard drives, but unfortunately their capacity is very small, often less than 1M.

Therefore, today’s computers simply cannot install any major software.

In fact, the reading and writing of the magnetic head of a mechanical hard disk is still based on the principle that magnetic information is converted into electrical signals and transmitted outward under the action of changes in the magnetic field.

Xiao Renming's major is still related to this.

During the discussion with Wang Haoran, Xiao Renming quickly realized the working principle of mechanical hard drives.

He felt that this mechanical hard drive was not that difficult to deal with.

While Wang Haoran was discussing with Xiao Renming, he was drawing a schematic diagram of the magnetic head on paper with a pen.

After more than two hours of discussion, it was already dark, and the design of a micro hard drive was already on paper.

Wang Haoran smiled and said, "Dad, look, I think the design we came up with through brainstorming should be pretty good."

"How about you implement this idea and make a sample?"

"You should form a technical team on your side. My suggestion is to bring in talents from various fields that are needed to collaborate."

Xiao Renming scratched his head and looked at Wang Haoran in a daze.

"Haoran, I feel like this whole creative idea seems to come from you!"

Wang Haoran waved his hand and said, "Dad, this is the result of our discussion! We discussed it together, revised it together, and finally came up with this design, didn't we?"

"If this solution is feasible, it will be a major revolution in mechanical hard drive technology!"

"Would you please give it a try?"

Xiao Renming sighed. He knew that his son-in-law was helping him again.

However, Haoran was right. He couldn't do so much work by himself. Even if it was his creative idea, he needed someone to help him with the work.

Everything is done to develop an advanced domestic electronic computer production line as quickly as possible.

Thinking of this, Xiao Renming said, "Okay! Then I'll help you take a look and test this idea."

Wang Haoran smiled and said, "Thank you for your hard work, Dad."

Xiao Renming waved his hand and said, "Why work so hard? Everything is for the country!"

……

Wang Haoran visited his partners for several consecutive days.

He basically divided up the task of developing each important component of the computer.

Of course, while visiting partners, he was also perfecting the design of his vision for Longguo's first application-oriented computer.

He drew the final draft of the overall design plan and determined the technical routes for each important component.

Time flies, and in a blink of an eye, it is already mid-January 1979. There are still more than 10 days to the Spring Festival.

At this time, Wang Haoran had already held several meetings with the research team and clearly assigned tasks.

Of course, for the display, after he drew the process design drawings, he communicated directly with Tang Jianming of the Beijing Television Factory.

He wanted Tang Jianming's Beijing TV Factory to be responsible for the production of monitors.

Today, the Beijing Television Factory has become a very prosperous large enterprise in Beijing.

It has installed two color TV production lines, with an annual output of more than 2 color TV sets.

Great Wall brand color TVs are sold well all over the country, and have even suppressed the Jinshi TV Factory.

In fact, the principle of color TV is exactly the same as that of monitor.

As long as the design drawings are provided, color TV manufacturers can produce monitors.

Tang Jianming was also very grateful to Wang Haoran.

If it weren't for Wang Haoran's persuasion, he wouldn't have made up his mind to do everything he could to purchase and install a domestic color TV production line.

Judging from the current situation, this move has been very successful.

Tang Jianming naturally agreed to the task assigned by Wang Haoran.

He held the blueprint and said to Wang Haoran: "Comrade Haoran, don't worry! We will definitely go all out and strive to produce the display sample as soon as possible!"

Wang Haoran smiled and said, "Thank you Director Tang for your cooperation!"

"As long as you can produce monitors with guaranteed quality and quantity, it is equivalent to expanding a new business!"

"In the future, this computer will definitely be promoted nationwide!"

"You will reach new heights with this new business! Come on!"

After explaining the task to Tang Jianming, the project assignment was completed.

Wang Haoran himself is mainly responsible for the development of new computer CPUs and motherboards.

This is the heart of the computer and is very important.

When designing these two items, Wang Haoran specifically used foreign computers imported from the Computer Institute of the Chinese Academy of Sciences.

When he was using this expensive imported computer, he felt it was really difficult to use, with only 64K of memory and 512K of hard disk.

When doing a design, it takes several minutes to more than ten minutes to respond to each step.

Wang Haoran was tortured to the point of ecstasy and was almost going crazy.

But he got the design done anyway.

Wang Haoran swore secretly: I must hurry up and assemble a domestic high-performance computer!

That afternoon, when Wang Haoran returned to the office, the director of the school office came to tell him that Zhang Yongcun, the director of Factory 742, wanted him to call back...
