Since he intercepted a piece of the 8080 microprocessor as an experimental product and made it into a microcomputer, Li Mengyang has almost become obsessed with this toy, soaking in it every day, and exploring all the functions of this electronic monster with crazy madness.

Cao Changjiu is also very evil "guiding" Da Li, such as:

"Finally, there is a look, it looks so beautiful!" Da Li had stars in his eyes.

"It's not a good look, the input method is too primitive, and in this era, it still uses machine code input, backward!" someone spared no effort to hit him.

"Oh, since we have it, we want to be the most advanced, we are a scientific research unit, why don't you have it? You say, how can you change the input method?"

"At least you have to change to an 85 keyboard, so it's more interesting. ”

"Earlier, we have it, who asked you to design this binary button, so I thought that microcomputers were like this. He ran out, and after a while he came back with a big keyboard in his arms.

After Cao Changjiu's tinkering, the first microcomputer in Chinese history finally has its own keyboard, and Da Li can be regarded as a learner.

Da Li was moved to tears, and affectionately stroked the thick keyboard, as if he was very intoxicated by this feeling: "Baby, you are the most advanced now!"

"It's almost time to make a typewriter, hehe, it's still a garbage typewriter. The serpent still spat out the letter and spewed venom from its mouth.

"Is this something missing?"

"What do you say? Input and output are complementary to each other, you just have a keyboard to use, at least a monitor is enough. ”

"Yes!" Da Li suddenly said, "We used to have a monitor in the warehouse, French goods, I don't know if it's good or not." ”

"There's a monitor? This is a good thing!" It was Cao Chang's turn to be pleasantly surprised, originally he was still a little worried that modifying the TV would add a lot of trouble, who knew that Da Li actually still hid this thing, this thing itself is digital.

Wait, why do you say before, "Before, ......was there before?"

"That's good!" Da Li nodded vigorously, "Now it's gone, the French carried forward the spirit of internationalism, regardless of the obstruction of the international community, and resolutely sold a batch of monitors to Shanghai Airport, making a lot of money." Later, the airport gave us a few units, and a year ago it broke again, and it couldn't be repaired, so it was thrown directly into the warehouse, and then it was disposed of. Da Li felt that he had finally played a game for a long time, and he smirked.

Cao Changjiu was simply crazy, "It's all dealt with, then you haven't said the same as if you didn't say it," but he always felt that Da Li was smiling very much, and there must be a bucket of bad water in his chest.

Sure enough, Da Li smiled enough and finally shook out the burden: "It's just that Uncle Li had a discerning eye back then, and bought it with great wisdom and perseverance, and he was alive~~~"

"Look at the bear you are smiling, I knew you would be ambushed, so don't you contribute quickly!"

"Right away, you wait. ”

Da Li brought a square-looking, old-fashioned, got acquainted with a big box, about eight inches of black and white screen, the coolest thing is that it actually integrates an 8-bit RS232 interface, that is, this thing can be connected to almost all computer systems, because RS232 is a universal interface standard.

It took two days to modify the system and add the display crossover circuit, and Da Li and Changjiu finally successfully used French goods and became the first batch of people in China to use microcomputers.

So far, Cao Changjiu has successfully led Da Li into the door, due to his own solid foundation in electronics, for the formation of a microcomputer system, Da Li has a clear mind, resolutely entered the ranks of DIY.

In short, for the upgrade of this personal computer, Da Li did everything he could, used his personal connections, and picked up a floppy disk machine. Of course, Cao Changjiu also gave Da Li his disk operating system for free.

Da Li's interest in microcomputers is a thousand miles a day, a pour, a burst of effort, and out of control, in the system that Cao Changchang gave him wantonly exerted his imagination.

However, in the case of this self-assembled copycat machine, the computing power can really be compared to the low-end mobile phones of later generations, slightly behind, and equal.

Although Da Li felt that he was already very happy, and he didn't even go to the game room, he couldn't help but belittle the performance of the machine for a long time, and couldn't help but think about whether he should help Changjiu make a processor with extremely high performance and extremely cool to use.

Of course, Da Li also has his own considerations, since he pounced on this toy, he has not worked hard, although he has no tasks now, but he can't always mix like this.

Helping Cao Changjiu make microprocessor chips can also be regarded as research work, Da Li thought.

Just when Da Li made up his mind to confess to Changjiu that he wanted to create an era with him, Changchang was going back.

It turned out that there was a telegram from Beijing, and Mr. Wang obviously had reached the limit of his patience for a long time, and there were only four words in the telegram: test the machine and return quickly!

Cao Changchang had to leave for the computing institute even if he had all kinds of reasons.

Director Mei personally arranged the train ticket for Cao Changjiu, and he really couldn't get rid of it, so he asked Li Mengyang to send it.

Although Cao Changjiu and Li Mengyang have only been together for a short month, they have the same hobbies and have experienced so many things, but they are like old friends for many years, talking about everything with each other.

Before leaving, Li Mengyang took out a bag, which was a variety of snacks, and said that he would eat it for a long time, but he couldn't help crying.

Temperamental, Cao Changjiu took it with a smile and said, "Thank you, see you in the future!" The voice couldn't hide his choked voice.

The car drove for a long time, and I still saw Da Li waving to him at the window for a long time, and finally couldn't help it, his nose was sore, and tears dripped down uncontrollably.

Da Li is the first person in this strange world to treat him as a brother of the same generation, doing things together, stealing food together, playing games together, bragging B together, and not treating him as a little kid at all, which makes Cao Changjiu, who has been lonely for a long time, really have a sense of belonging, and seems to have returned to the days when he used to get along with his bosom friends.

The little girl opposite seemed to be very interested in this little brother crying alone, and asked her mother: "Mom, look at him, he still cries when he is so old, and he is not shy, Xiaoyun doesn't cry." He also made a grimace at Cao Changjiu,

"Yes, Xiaoyun is the bravest, Xiaoyun has grown up and will never cry anymore. The woman looked apologetically for a long time, smiling and coaxing her daughter.

Cao Changjiu was also amused, took out the bag that Da Li gave him, took out a few pieces of White Rabbit milk candy and handed it to the little girl: "Big brother didn't eat candy when he was a child, I always want to have candy to eat, and now a friend gave me so much candy, and my big brother was moved to tears." Well, this one is for you to eat. ”

The woman hurriedly excused herself and said don't want to, but her daughter stretched out her hand to take the candy, and the woman was embarrassed, so she had to say to her daughter: "Thank you little brother yet!"

The girl had already peeled a piece of white rabbit and stuffed it in her mouth, and said thank you vaguely, but she almost didn't get rid of the sugar. Cao Changle laughed, the girl was embarrassed, but she grabbed the candy in her hand.

Director Mei gave a long train ticket or a soft sleeper, and he and his mother and daughter were in the carriage, and a few pieces of candy were delivered, which narrowed the distance between the three people and diluted the strangeness.

After talking, Cao Changjiu learned that the woman was going to visit relatives and go home, and her husband was an officer in a certain department in Shanghai.

"It turned out that she was still a military wife, what a disrespect!"

"Aren't you also a military family? Then she said her own thing.

She herself is a Beijinger, and she took her daughter to Shanghai to visit relatives for a few days, and she wanted to spend a few days with love, but her husband received a notice that there was a task and all of them canceled their vacations.

She was very reluctant, but she firmly supported her husband, although he left without even saying a word, and let her go home by herself.

When the woman talked about this matter, her tone seemed to be holding back for a long time, and she seemed to be talking to herself, but the expression on her face revealed mixed feelings.

After a long silence, he knew that he only needed to be a listener now, but in his heart he blessed this officer who had never met before, because he went to defend the frontier.

Along the way, the three of them chatted with friends for a few days, during which they consumed a few snacks, which made the girl laugh countless times, and screamed one brother after another, which made Chang Chang very happy.

When she got off the bus in Beijing, the woman touched Cao Changjiu's head and said, "What a sensible child!" and left, while the girl waved her hand vigorously on her mother's shoulder and shouted: "Big brother, goodbye!"

Cao Changjiu also waved goodbye to her, and laboriously picked up his things and left the station.
