When the class officially began, a man who looked to be in his thirties walked up to the podium, holding a handout folder in his hand, and wearing a suit and leather tie shirt. Zhang Lexing muttered in his heart: "Could it be that the legendary American lecturer is this?"

Mr. Huaqiao put the handout folder in his hand on the stage and began to introduce himself, and his voice was very good, which is commonly known as Chinese. As soon as he opened his mouth, he said: "Everyone comes from all over the world is also fate, let me introduce myself first, my name is Yu Youcheng." His ancestral home is Shanghai. After half a lifetime of wandering outside, I am fortunate to be here with all of you this time, and I will talk to you about the prospects for the development of microcomputers. ”

"The microprocessor is the core of the microcomputer, it was first born nine years ago, when Intel Corporation introduced the 4-bit microprocessor 4004, which ushered in a new era......" After the opening remarks, Mr. Yu began to introduce microprocessors and microcomputers.

said quite wonderfully, but unfortunately Zhang Lexing didn't listen to a word, from the moment he heard the words "Yu Youcheng" just now, his brain exploded, as if he had been struck by lightning, and began to flash some things about Yu Youcheng.

Yu Youcheng, the backbone of Intel Corporation, has held many important positions in semiconductor technology, transistor and other product planning, and has become a member of the International Institute of Electrical and Electronics Engineers and a member of the Stanford Computer Science and Systems Committee, and has also presided over the development of 386, 486, Pentium, Pentium II, etc.

Zhang Lexing didn't understand why such a famous person couldn't do the promising job of CPU (central processing unit) design, but he went to the mainland to do some kind of training class, which is too out of bounds.

There is no end to learning, and there is less hatred when the book is used, please forgive Zhang Lexing's young ignorance. In fact, Yu Youcheng used to mix well in Intel, but unfortunately since he ran out to start his own business in 77, Yu Youcheng has been frustrated, not only the home computer that embodies the hard work of him and his partners has suffered a fiasco, but even the home computer designed by another company that has the courage to try the home market has become a floating cloud. The experience of the past three years can be described in a few words, that is, "pounce and pounce". Coming to the mainland to open a computer training course is also a last resort, and if you don't want to find a way to make some money, you won't have anything to eat. In this way, Yu Youcheng appeared in Chinese mainland, which had just begun reform and opening up, and began his gold rush journey......

Dr. Yu on the podium was very interested, and he found that after a vivid speech, the enthusiasm of the students in the audience had been mobilized, as if the door of the microcomputer era was slowly opening not far ahead. Dr. Yu felt that the heat was almost over, and reached out to pull the cloth on the big table next to the podium open, revealing the focus of today's training session, of course, it is also the main product of his class to earn money, a Cromemco microcomputer, using 8085 microprocessor, the operating system is CP/M, and comes with BASIC and other software.

As the saying goes, it's better to see than to hear. The students who were taking notes seriously just now were boiling, and they all stretched their necks to look at the mysterious machine, and even a few students in the back couldn't help but lean forward. Zhang Lexing didn't move at all, this will still be immersed in the memories of Yu Youcheng, even if he looks at the computer now, it is estimated that the most he thinks is that the screen is not as handsome as Apple II, and the host is not as small as Apple II, so naturally there will be no praise.

Soon the class was over, and Dr. Yu looked at the many students who were watching around the Cromemco microcomputer, and a sense of accomplishment came to him. It can be said that these mainland students have not come into contact with microcomputers, and many of them may not even know anything about computers, but after his encouragement, their willingness to learn is quite high, and now their interest in microcomputers seems to be like that of children who are obsessed with toys.

Dr. Yu's original idea was to come to the mainland to make some money, who made the mainland's market potential greater. But now he feels that with his efforts, the introduction of microcomputers to the mainland, so that Western science and technology began to take root in the motherland, not only opened up the horizons of many people, but also spread the knowledge of microcomputers, he felt as if he was like the general god who stole fire in Western mythology, which made his vanity a little satisfied. He had a gut feeling that this wildfire would one day burn the whole world.

Zhang Lexing also came back to his senses at this time, he saw Dr. Yu standing on the stage in a daze with an intoxicated face, and decided that whether it was Intel's Yu Youcheng or not, he had to ask, maybe there would be some good opportunities, so he got up and walked to Dr. Yu to take a look.

Seeing a teenager coming over, Dr. Yu wondered if there were still child laborers in the mainland, and he still remained polite: "Same ...... Hello comrade, is there something wrong?"

Zhang Lexing restrained the fluctuations in his heart and asked softly: "Hello! Are you Yu Youcheng of Intel Corporation?"

"I used to do it at Intel, you are ......" Dr. Yu was shocked, how could anyone in the mainland know about him, he thought about it, he should not have done anything related to national security during this time.

"It's true!" Zhang Lexing excitedly grabbed Dr. Yu's hand, "I have admired your name for a long time." ”

Zhang Lexing knew that Dr. Yu was the best opportunity he could grasp in front of him, and if he just let it go, he didn't know that he would have to wait until the Year of the Monkey next time, so he began to work hard to talk to Dr. Yu. After introducing his name, the conversation between the two began with the development of microcomputers, but he did not expect to lead to Dr. Yu's experience in the past few years.

"When I joined Intel, Intel had already introduced a microprocessor 4004, which was originally intended for a Japanese company's calculator. Later, the processor chip became smaller and smaller, and the performance became higher and higher, and I began to think about the question, what can it do? In fact, I am not the only one who is thinking about it, but the whole industry is thinking about it. ”

"In 1975, a company called MITS launched the Cowherd Star 8800, which should be the first relatively successful microcomputer, and in 1976, someone invented the first generation of TV game instrument 'Pong' with a simple microprocessor. On a whim, I thought that the biggest potential market for microprocessors should be 'home computers', which is something that every home can accept. ”

"Think about it, how many families in the United States, one in 10,000 people can sell as many microprocessors and memories as they buy a home computer. With billions of people in the world, this can solve the problem of millions of microprocessors and memories. ”

"I discussed this idea with some people within the company, but most of them were not interested, because they saw microprocessors as the right way to industrial control, without considering that microprocessors could have more new commercial uses. Only one friend was moved by my words, and they worked together for this illusory goal. We plan on paper all day long, weaving home computer dreams in our minds. ”

"Gradually, we were no longer satisfied with just keeping our ideas on paper, so we started thinking about starting a business, and soon I was able to raise $1 million in initial funding. In January '77, I left Intel with my dreams in mind, registered my own company, VideoBrain, and started designing my home computer. My old boss, Andy Grove, was not supportive of my departure, and he was skeptical that there was a market for home computers and suggested that I should do it step by step, and in retrospect he was right. ”

"Dr. Yu, I really admire your passion for entrepreneurship!" Zhang Lexing said, in fact, what he admires more in his heart is Dr. Yu's courage. Zhang Lexing remembers that the home computer market should have only begun to grow after the advent of multimedia in 1992, and before that, those who dared to set foot in the home computer market were almost one in the first place, and even the blue giant IBM encountered Waterloo in this regard. Dr. Yu was able to start in 1977, and he could not think of any other adjective than courage.

Dr. Yu continued, "It was a really passionate, and with the joint efforts of everyone, we quickly came up with our own product, which is called VideoBrain, just like the name of the company. In order to provide the best image quality, this home computer is equipped with a dedicated image processing chip, and all the software is stored in read-only memory, just like the cartridges of the popular Atari game consoles. We started with computer checkers, BASIC, financial management software, and even the ability to connect to computer databases. These functions are difficult to do on a microcomputer, and some people have been thinking that these software are myths that cannot be achieved until they are made. ”

"It was really difficult for us to design software for this home computer, because there was no BASIC language at the beginning, and our software designers had to develop the software in a combination language (assembly language). At that time, floppy drives were mainly used on mainframes, and we had to use audio tapes to store programmed programs. I didn't expect that under such difficult conditions, we actually completed more than a dozen software, and now I can't believe it in retrospect. ”

"By the first half of '78, we felt we were well prepared, and we exhibited our brainchild at that year's Consumer Electronics Show in Chicago, which we called 'the first-ever home computer.'" It was that time that I saw Apple's Apple II and Jobs for the first time. At the exhibition, we received a lot of orders, and my business partners and I had a feeling of high spirits, and success seemed to be just around the corner. ”
