Chapter 70 Half a day is half a day

A Yuan's eyes when he looked at Li Sanbiao gradually became complicated, full of unknowns and curiosity.

Li Sanbiao was seen talking in front of her with his head lowered. The content was casual and he talked about many other CPU design ideas.

Because he was so engrossed in what he was talking about, he lowered his head and closed his eyes when speaking. In fact, he was trying his best to follow the pace of the third AI master’s narration, and his posture was like the sleeping great detective Mouri Kogoro.

If he were not talking, others would mistakenly think that he was asleep with his eyes closed.

When he finished speaking, he looked up and saw that there were more than a hundred people surrounding him, and a tape recorder was placed in front of him at some point!

Chief Engineer Xing couldn't believe it and said: "Comrade Li Sanbiao, I didn't expect you to have such high attainments in chip manufacturing! I am really ashamed to be your teacher! Otherwise, you can teach my class at night!"

Li Sanbiao said hurriedly: "You are serious in your words. How dare you? I'm just doing my own thing!"

But as soon as an expert reaches out, he will know whether there is something there. No one will treat Li Sanbiao as an amateur again.

Even though he used the "I have a classmate" series and the "I have a relative" series, they accidentally revealed them during their chat.

But what Li Sanbiao talked about were all technical points in actual design and production. They were all insights and could never be learned through books and classes.

Then, Li Sanbiao started the question-and-answer mode. Many engineers from the 878 Factory briefly described the difficulties at work. The third uncle quickly borrowed Li Sanbiao's words and gave the answer.

A Yuan's mind is even more confused. What kind of man is this? He is even more powerful than a genius girl like himself!

Everyone thought she graduated from college at the age of 22, but that was not the case.

She is only 18 years old this year! That’s why she looks so petite and delicate, with a pleasant personality and no sense of maturity at all!

A Yuan suddenly remembered a question that had been lingering on her for a long time: "Brother A Biao, what do you think is the most effective way to improve the computing power of display chips?"

Li Sanbiao replied: "You can use multi-core computing. It is not as complicated as a CPU. The task of the display chip is very simple, which is to render images. You divide the display chip into dozens of simple logical operation units, and each unit is responsible for a small part of the screen.

That’ll be fine.”

A Yuan's tone was full of surprise, and he whispered in his ear: "Okay! Thank you, Brother A Biao!"

Only then did Li Sanbiao remember that A Yuan seemed to have asked this!

Wait, why is she asking?

After more than an hour of answering questions, Li Sanbiao has completely convinced these professional chip engineers.

Mr. Xing was very excited and said: "Sanbiao, don't work at the 789 factory. Come to us! Help us develop new chips. You can use these equipment as you wish!"

Li Sanbiao actually already has chip equipment. If he had not purchased the old production line of Huaqiang Factory, he might have considered it, but now that he no longer needs it, he declined.

Li Sanbiao said; "However, I am indeed here to borrow your equipment for research and development. I have promised our chief engineer to develop a calculator. Please help me, let's start now!"

Everyone was confused. It turned out that you came to borrow equipment to work after having gone through such a big circle!

Mr. Xing immediately asked Fu Gong and Xiaopo to help Li Sanbiao and began to collect the accessories Li Sanbiao needed.

Inside the calculator is a large printed circuit board.

Li Sanbiao quickly drew a printed circuit board, marked the location and model of the components, and said: "You just need to make one by hand according to the signs on it."

These are all basic operations. Xiaopo skillfully took out a piece of copper-clad board, then polished it with sandpaper, used a marker to draw the wiring of the wires on it, then prepared a corrosion potion whose main component was iron trioxide, and threw away the copper-clad board.

Go in, and after a few hours, the copper wire where the marker scratched was left because it was wrapped in an oil film, while other copper wires were corroded.

Then wrap a layer of solder resist paint on the outside of the board. The general color is green, so the motherboards are all green.

Then weld pins, golden fingers and other sockets on the board to connect with the designed components.

At this time, Li Sanbiao had designed a programmable calculator chip on the computer and written an instruction set into it.

By the time the calculator motherboard is finished, this chip will also be finished.

Factory 774 has already produced a long LCD screen.

Someone helped make a keyboard, pasted conductive rubber on it, and handwritten numbers, squares, square roots and other symbols on the keys.

After putting them all in a plastic case and installing the battery, the calculator's LCD screen lit up immediately and started working successfully.

The newly manufactured audio chip is also overkill. It is pressed on the motherboard, and a memory is specially prepared for it to store the key tone.

As long as you press the button, you can hear the sound of "1, 2, 3, return to 0"!

Of course, there is also programming function, which is the same as the function of the later Casio calculator. It can: sum up various series, multiply and other operations, solve Newton's equations, guess numbers, financial management games, etc.

Li Sanbiao randomly calculated a few questions and the answers were completely correct.

"A Yuan, you can try a complicated question. How is the programming function of this calculator?"

A Yuan looked at this calculator with a complicated expression. Why did this person say he was going to make it and then he made it in one day?

She casually wrote a small program to find the sum of the squares of the numbers 1 to 10.

Li Sanbiao discovered that A Yuan was very proficient in programming calculators, which was beyond his expectation.

Although he is a top student at the 49th City University of Posts and Telecommunications, his level of proficiency is a bit too weird for the current Dragon Kingdom.

A Yuan: "Brother A Biao, no problem, you are really good! But I want to know, where did the calculator chip program you wrote come from?"

Of course Li Sanbiao would not tell the truth, he just said that he had already thought about it.

A Yuan said with a look of disbelief: "Brother A Biao, let me see, which foreign company did you steal it from? Who did you steal it from? Don't lie!"

Li Sanbiao acted like a scoundrel: "Don't accuse people unfairly, okay, I'll tell the truth, I dreamed it myself!"

A Yuan turned his head away angrily and didn't ask any more questions.

While the two were still entangled, the director of Factory 878 led all the leaders to the scene.

With the experience of almost being in the newspaper last time, Li Sanbiao anticipated what was going to happen and quickly ran away with his calculator.

He has told Chief Engineer Xing and Fu Gong about the production methods and key points, and also handed over the calculation program to them. Let them enjoy the honor of successful research and development.

All he needs to do is quietly produce and make a fortune.

Before get off work, Li Sanbiao and A Yuan returned to the research institute with the calculator he made.

It really took just half a day to make!
Chapter completed!
