The ups and downs of life in the Siheyuan

Bangge's personality has changed a lot since I passed away, but fortunately, Qin Huairu has always been there to hold her down, so I can usually see him fine.

Qin Huairu is not an easy woman. She thought she would be blessed when she married in the city.

As a result, she became a widow at a young age.

It doesn’t matter if you are not very good-looking, but you are born with a charming eye, and it is normal for you to be remembered after being widowed.

According to rumors, I worked with a deputy factory director. Although I was a small person, I could still survive.

Otherwise, life would definitely be difficult for two widows with three children.

Today, due to a strange combination of circumstances, I helped them, so I am grateful and it is not a loss.

The next day, Zhao Laosan, who wanted to die, really sent someone to investigate Li Yuan.

In the evening, he was invited away for tea. For a long time, no one saw this bad guy on the street again.

Although Liu Haizhong was easily impulsive, seeing that Yi Zhonghai didn't respond, he calmed down and thought about it, and he could guess something.

Therefore, he just acted like a turtle and escaped disaster.

Li Yuan doesn't need to worry about these things, there will be dedicated people to help handle them.

Time flies, time flies, and time flies by inadvertently.

In early September 1965, the autumn air was crisp, the grass was growing, and the orioles were flying.

On the central test bench of the 621 laboratory hall, there is a desktop computer similar to that of later generations, named "Kaitian 6501".

"Kaitian 6501" means the creation of the world, "65" represents 1965, and "01" represents the first version.

The main parameters of the basic configuration are as follows:

CPU: Pangu, PG32V01;

Main frequency: 12MHz;

Memory: 64Kb;

Program storage: 128Kb FLASH;

Motherboard: Fuxi V1.0;

Input device: keyboard, mouse

Output device: CRT black and white monitor;

External interface: 2 RS485, 1 USB;

Internal interface: IDE hard disk interface;

Operating system: Hongmeng V1.0;

Chinese character library: simplified Chinese;

Word processing software: Cangjie V1.0.

CRT monitor, scientifically known as "cathode ray picture tube", is a monitor using a cathode ray tube.

It mainly consists of five parts: electron gun, deflection coil, shadow mask, high-voltage graphite electrode and phosphor coating and glass shell.

CRT displays rely on electron beams to excite phosphors on the inner surface of the screen to display images. Since the phosphors extinguish soon after being lit, the electron gun must continuously excite these points in a cycle.

This is known as electron beam scanning.

CPU Pangu series PG32V01, internal 32-bit bus width, external 16-bit bus width, maximum bus rate is 10Mbps.

The maximum reserved bus addressing range is 512M.

The external program storage FLASH is 128Kb, and the external data storage RAM is 64Kb.

The simplified version of the USB interface supports a maximum dump capacity of 2Mb.

Hongmeng V1.0 operating system can only perform command line operations, and the installation size is less than 64Kb.

Font library: 3000 commonly used Chinese characters.

据统计，1000个常用字能覆盖约92%的书面资料，2000字可覆盖98%以上，3000字可覆盖99%以上。

Hao Wei (formerly Yang Qingsheng) is writing lines of code.

The file is formed, compiled, executed directly, and a pinball game appears on the monitor.

After trying it for a few minutes, it ran smoothly, and people in the circle suddenly cheered.

Then use relatively simple text operations. The text processing software is a small program that comes with the system, named "Cangjie".

After an hour, all functions are tested.

Everyone cheered again.

Next, a row of five "Kaitian 5" machines was filled with people, and everyone was testing them.

This is the result of more than a year's hard work by everyone in the centralized laboratory, and everyone put down their work with excitement.

Another half month has passed, and now basically everyone has an "Open Sky" computer.

All problems discovered during this period have been resolved.

On September 1965, 9, in a heavily guarded compound, major experts from all walks of life and several leaders of the First Machinery Department were gathered in a large conference room.

The only people Li Yuan knew were Principal Jiang, Old General Tan in plainclothes, Representative Tong and Leader Xu.

First, Leader Xu announced the confidentiality regulations, and all the more than 50 people attending the meeting recited them.

“The results shown to you today are the latest research from our secret experiments.

Preliminary assessment shows that the technical level far exceeds that of other countries in the world during the same period.

Now I invite Li Yuan, director of the National 621 Key Laboratory, to show it to everyone."

Li Yuan's youth once again shocked everyone.

Most of the more than 50 people sitting here had the impression that when they saw Li Yuan just now, they thought it was some leadership assistant.

I didn't expect that it would surprise them, powerful people like them in the industry.

Everyone watched with careful eyes as Li Yuan walked to the right side of the podium.

There was a table there, covered with a red cloth.

Li Yuan had neither stage fright nor humility. He opened the red cloth with one hand, and something he had never seen before appeared in front of everyone.

Everyone made guesses, but unfortunately no one was right.

Li Yuan did not hesitate, sat on the stool with his back to the audience, and started the computer directly.

At this time, Representative Tong walked to the table with a microphone and a piece of paper in his palm.

"Please see, this is a brand new computer, with a 16-bit floating point operation speed of 600 million operations per second. It is the fastest computer today.

Its power consumption is only 120W, and it can process text and perform scientific calculations.

You can also control the work of other devices through external interfaces, and can connect up to 32 devices.

Through bus extenders, it can be expanded to more devices."

At this time, Li Yuan opened an empty file and started typing.

"Okay, what I am using now is Cangjie word processing software, which can edit and store text.

Cangjie was an ancient sage and the compiler of Chinese characters.

He extensively collected existing folk pictographs and carefully organized them to create a systematic and standardized set of pictographs."

Li Yuan skillfully operated the computer, and words appeared on the screen quickly one by one. Many people ignored him and crowded behind Li Yuan.

"This is amazing. It can actually display Chinese characters, and the typing speed is no slower than a typewriter!"

"Yes, this young man is playing too smoothly!"

“You see this rectangular thing called a keyboard, which can be used to edit text using Chinese Pinyin.

The thing next to it doesn’t look like a mouse with a long tail. It’s called a mouse and is used for positioning.” Representative Tong became the narrator for the first time.

“Look here, everyone, this cuboid, we call it the host, is also the core of the computer.

The heart inside is a CPU with multiple transistors called Pangu PG32V01.

With a main frequency of up to 12MHz, it is the brain of the entire computer, which can also be said to be the heart.

This big thing is called a monitor, and everyone thinks it looks like a TV."

After saying that, I even made myself laugh.

At this time, Li Yuan closed the text file, opened a new file, and wrote more than a dozen lines of code.

Compile and run, and a line of text appears on the screen, "For multiplication calculation, please output any two numbers not exceeding 16 digits."

Li Yuan entered two floating point numbers and clicked Enter.

Immediately a long list of data appeared on the screen.

A group of experts nodded frequently. They were all experts in various industries. After just a preliminary demonstration, they knew how powerful this computer was.
