Bit Mania [Hacking]

"Computer!" Zixin looked at the white and yellow machine in front of him in disbelief.If he was full of excitement and anticipation when he saw Big Brother before, now a computer is in front of him, just like an ordinary civilian walking on a road that he passes every day, suddenly Finding the queen of her own country standing at the intersection, she gave herself a dignified smile.

In 1991, Huaguo had not yet stepped into the Internet era, and PCs had not yet been popularized. Most computers were only used for scientific research or high-level office work, and it was difficult to find such things as civilian computers on the market. Recognizing it is not because I have been in contact with it before, but because I have glimpsed it in the report about the latest technology on the TV news in the past.

At that time, the TV camera happened to be pulled into a research and development laboratory. Three academic workers in white coats were sitting in front of a TV-like screen. The oblate object used to operate the computer, the white case, was placed on the table.

Luo Zixin, who was sitting in front of the TV at that time, subconsciously jumped off his chair and walked forward, wanting to watch it more carefully, but the news had already changed to the mayor receiving foreign guests, which made him deeply disappointed.The only thing I heard in time was that this thing is called a computer, and it is manufactured by integrating tens of thousands of transistors on a silicon chip. It can perform calculations, and the calculation speed is as high as hundreds of millions per second!

5000 million, what a shocking unit in the eyes of the Chinese people at that time. You must know that the annual domestic steel production at that time was only [-] million tons!

It is such a horrible creation, it also has a name called "computer".Perhaps in normal times, people have heard of this alias, but Luo Zixin, as a person immersed in electronics, can't think so.The brain is the most important thing for a person. It controls all behaviors of a person's life. It is mysterious and powerful. Now there is something called "electronic brain", which is enough to see that it is in the electrical family. What a place it occupies!

"You're right, kid," one of the youths pushed his glasses. "This is a computer. Can you fix it?"

As an old electrician, Luo's father still understands the market: "... I am afraid that this thing must be repaired by professionals. How did you get it? Logically speaking, such high-end electrical appliances should not be It was moved out to be repaired by outsiders. Where it used to be, is there no one who specializes in repairing this thing?"

"Oh, to be honest, we moved out this computer secretly." The two young men looked at each other with wry smiles.

It turned out that they were students from a nearby university. The young man wearing glasses was named Lin Guang, and the other baby-faced boy was named Li Yunze.They majored in computer science, which was definitely new at the time, and their graduation projects also needed to be operated on computers before they could draw data and write papers. However, computers are a brand-new concept after all. It is also new and abstract, and it is very difficult to learn, so they can only borrow keys from their instructors and work overtime to borrow computers to research topics. Unexpectedly, due to improper operation, the computer broke down under their hands, and it can no longer be turned on normally.

The two were shocked, and decided to secretly find someone to repair it without telling the professor, because if the professor knew about it, they would not only have to compensate for the loss of the computer, but more importantly, they might lose their diplomas.However, after looking for many people, they all ended in failure. In desperation, they had no choice but to bite the bullet and ask around for talented craftsmen to try their luck. Luo Hui's repair shop was already the last stop. A dead horse becomes a living horse doctor.

"This...I'm afraid we can't do it." Father Luo looked embarrassed.

"Even you can't do it?!" Lin Guang wearing glasses was anxious like an ant on a hot pot, but April Hanchun was sweating profusely: "It's over, it's over, we're in trouble now! The professor will definitely kill us !"

Li Yunze also looked like he was about to cry: "A computer! Even if we sell the two of us, I don't know where to buy one... I, I don't want to be expelled from school!"

Disappointment enveloped the two of them. They bowed down and wanted to move the computer away, but they couldn't lift it up after trying hard. Looking down, it was the little boy from Master Luo's family who had recognized the computer before. Holding the case with both hands, staring at the inside through the hollow baffle at the back, his eyes are full of fanaticism and obsession, the scorching sight almost burns the machine in his hand.

It was the first time for them to see someone who could look at something so intently, as if he didn't pay attention to anything in the world, and his eyes could only focus on this unremarkable and bulky machine in front of him.

"Well, since you guys can't fix it..." Lin Guang swallowed, and waved his hand in front of the child: "We're going to move it away, kid, let go."

Zixin's eyes blurred, and it was like waking up from a start. The college students thought he would obediently let go, but they didn't expect the boy to stretch out his arms and hug the case even tighter.

"Xiu...yes, Xiu!" The exquisite structure of the computer that has never been seen before completely attracted Zixin, making him almost incoherent even now: "Please let me try!"

"Try what?" The young people were also in a daze, not sure if what the other party said meant what they understood.

"Let me try to fix it!" Luo Zixin hugged the computer in front of him tightly: "I can understand it, I can understand it!"

Keep it, be sure to keep it, there is only one chance!A voice in his heart was shouting vigorously, and the boy's mind was running fast. The memories of all the electrical appliances, components, parameters, and theories he had been in contact with over the years were all recalled, passing through his mind like a revolving lantern, constantly Overlap and combine with the machine in front of you.

"Here," he pointed to the central processing unit: "This should be the system core of the entire computer, and its function is calculation and control."

"And here, according to its circuit and chip structure, it should be an electronic storage device, and it will be reset to zero when the computer is turned off."

"This one is made of a metal magnetic plate. The magnetic plate has a memory function, so it can permanently store the codes of 0 and 1, even without power!"

"And this, this, this..." If at first Luo Zixin wanted to prove that he could do it, then he unconsciously put all his energy into it, and the mysterious structure of the computer was revealed one by one following the direction of the boy's fingers. open.

The two college students majoring in computer science looked in the direction of the boy's finger, gasped slightly unconsciously, and looked at each other, seeing surprise in each other's eyes.

"Xiao Xin," Luo Hui whispered to his son to emphasize a fact: "We have never repaired computers!"

"Don't be afraid." Luo Zixin had already made up his mind, and turned to the two customers: "Although I haven't repaired a computer before, I can understand its parts and time. Just give me some time and let me decipher it." How it works, I can try to fix it!"

"This, this is too absurd..." Li Yunze turned his head and looked at his classmates with questioning eyes: "We..."

Lin Guang gritted his teeth and stomped his feet: "Is there any worse situation than now!"

After a pause, his expression turned gray, and he said to Luo and his son: "If it can't be repaired, at least remember to restore it to its original state!"

After the two college students left their contact information, they left in a hurry. Luo Zixin bent down impatiently, and with all his strength in his thin body, he moved the large items into his room one by one, and carefully placed them on his desk. He turned around and gathered the manuscripts he had written before, trying to put them in the drawer, but was surprised to find that the half-written design drawing on the top was gone.

Zixin rummaged in the room for a long time, and finally looked down from the wide-open window. From time to time, under the window facing the street, a few pedestrians walked by with umbrellas, but there was no trace of the manuscript paper. Unfinished blueprints are lost.

But he didn't take this matter to heart, regrets are regrets, but with his head, those manuscript papers are just straightening out his own thoughts and writing them down, and the detailed content is all in his heart It's perfectly backed up.

What's more, there is one more obsessive thing nowadays, which is attracting almost all of the boy's attention.
