Siheyuan: Starting from a fitter

Chapter 155 Both Hard Disks Are Successful

In this era, there were no paternity leave provisions, so Li Guocheng went to work normally the next day.After being blessed with a daughter, Li Guocheng was full of motivation and quickly devoted himself to technology development, hoping to lay a solid future for his daughter and their generation.

I found one and a half kilograms of White Rabbit milk candies in a secret place, and gave two wedding candies to each of my colleagues in the laboratory, receiving lots of blessings.

"Brother Li, this is the mold drawing. These materials on the cart are what you requested. Tell me what you need." Zhou Xiaojuan put down the drawing and pointed to the cart.

"OK, thanks".

Li Guocheng became much more polite now that he had a little cotton-padded jacket. Before, he usually waved his hand to let him leave.

In this way, Li Guocheng was busy in the laboratory during the day and went home to tease Xiao Yu'er at night. He had endless fun.

This baby name was given by my mother-in-law. The reason was that in less than ten days, little Yu'er had grown into full bloom. She was pink and jade-like, and her skin was as white as snow. The mother-in-law thought it was very good to call her granddaughter Yu'er. It clearly meant that her skin was fair, and it implied that she was as holy as Yu'er. noble.

Time entered the beginning of May 1968. With everyone's joint efforts, the hard disk was finally finalized, and three samples were placed on Li Guocheng's workbench.The appearance is larger than the mature Seagate hard drive in later generations.The thickness is three thick of it.That's it, it is also the most advanced, largest-capacity, and smallest-volume industrial hard drive.

Li Guocheng named it YP32MG100. YP is the abbreviation of hard disk, 32M represents the capacity, G represents fixed installation, and 100 is the version number.

The redesigned motherboard is soldered and sits next to the hard drive.Next to the motherboard are three main chassis with power supplies.Under everyone's watchful eyes, Li Guocheng put the motherboard into the chassis, inserted the hard disk, tightened the screws, connected all the interfaces, checked that they were correct, and installed the side cover.

On the test bench in the laboratory, three computers were placed in a row.Zhang Zhijing, Zhou Xiaojuan, and Yan Jiefang each have one machine, waiting for test orders.

Wu Liankui, who rushed back from Changsha, accompanied Director Li and stood behind the three of them.

"Director Li, please give the test order," Li Guocheng invited.

Li Huaide looked around at everyone, turned back, and shouted excitedly: "Start!"

The three picked up their respective test cases, edited a piece of code using Pangu language on a DOS-like interface, then entered the save command and file name, and it was prompted that the save was successful.

Shut down the computer, turn it on, enter the open file command, and open the file just now. The code displayed on the screen is the code you just saved.And the test results of the three devices were all correct.

At this time, the three of them picked up a small black box next to them, the size of a cigarette box.This is a 2MB mobile hard disk, and the bus interface is exactly the same as the hard disk installed in the chassis, both of which are DB15 interfaces.

After the YP32MG100 design was completed, Li Guocheng thought why not design a mobile version?For ease of use, a single platter is used, and the platter is doubled in size.The secondary hard drive is named YP2MY100, and Y stands for mobile.

The three of them each inserted the mobile hard drive into the interface on the front panel of the host, transferred the files just now to the mobile hard drive, waited for 3 seconds, unplugged it, and passed the mobile hard drive to the next person in a loop.

When the three people announced that the basic test of the mobile hard drive was successful, everyone immediately burst into cheers, which indicated that the basic functions of both hard drives had been realized.

At this time, everyone was just happy and cheering, thinking that the laboratory had completed another product.But they definitely can't understand Li Guocheng's inner feelings now.

The success of the Sugon 103 computer research and development is by no means a design of a world-leading computer, but that during the development process, the team was trained, talents were trained, and production lines were established, laying a solid foundation for subsequent breakthroughs.

When the operating system design is completed, the Shuguang 103 computer with the operating system installed will become the possibility and cornerstone of all technological progress.

Looking at the cheering crowd, Li Guocheng shed tears silently.

At this time, Zhou Xiaojuan, who was careful, came over, "Brother Li, it's not enough, I'm still crying."

"It's okay, there's sand in my eyes," is an old-fashioned excuse, but it works.

Zhou Xiaojuan smiled and said nothing.

After a few minutes passed, Li Guocheng clapped his hands and said, "Everyone, be quiet. Next, the three of you will write code according to the test cases, and conduct full coverage testing, stress testing, and reliability testing on the hardware. This is a long-term job. Please Record test results daily."

The three of them sat down happily without any complaints and quickly entered the testing state.

Zhang Zhijing is installing the first version of the operating system 'Kunlun 68V1.0' on three computers. It is still very rudimentary and only has simple scheduling, file management and interface management functions.

Under the scheduling of the operating system, the compiled test program will automatically run, and the running heartbeat status and results will automatically be stored in the hard disk.So, when the test case runs, the three of them can continue their previous work.

Following Wu Liankui to Li Huaide's office, Li Huaide personally poured them a cup of tea.

"I didn't expect that the laboratory would have preliminary results so soon. I think I should be able to give the best gift on National Day."

Li Huaide was still worried. On this happy day, he hoped to hear Li Guocheng's affirmative answer.

"Director, don't worry, I promise to complete the task ahead of schedule."

"Okay, the leader of your laboratory is indeed courageous, and I will celebrate your achievements then," Li Huaide laughed.

"Old Wu, once the 103 model is finalized, you will be busy." Li Guocheng said hello in advance, so as not to be in a hurry when you get it.

"Don't worry, the more busy you are, the better!" Wu Liankui also made a hahaha noise.

The Dawn 103 computer was a milestone computer, and they didn't know what it meant.But there are so many research institutes in the country, and they are all experts, so we don’t know how big the storm will be.

"The two leaders took over the focus of our laboratory and planned to shift to the research of CNC machine tools. The 103 computer will be enough for the next 5 or 6 years. We only need to slowly optimize and improve it based on it.

Now that we have powerful computers, we can't just use them in special industries as we did in the past.Without economic benefits, there will be no subsequent investment in R&D funds.The combination of computers and machine tools can provide the strongest support for the development of our basic industry.

We all know that now they have started the research and development and application of CNC machine tools, and we must keep up, so as to ensure that the basic industry does not fall behind and compete with them."

Li Guocheng expressed his thoughts in one breath. Wu Liankui was a little unable to turn around, but Li Huaide was thoughtful and kept spinning the teacup with his hands.

Seeing the performance of the two of them, Li Guocheng also picked up his tea cup, savored it slowly, and waited for the result of Li Huaide's thinking.

No matter what, the possible consequences of the Sugon 103 computer must be discussed with Mr. Zhao in advance in the near future to avoid errors in judgment.
