Chapter 285: The third generation computer is completed, Qin Huairu comes to work
Next, it is the input and output components.
In this area, Li Yang also did a lot of work.
In addition to the essential punched paper tape and control console, he also added more advanced tape machines and magnetic drums.
Both of these were high-tech equipment at the time, large in size and expensive.
But in the small world, it is easy to create them?1?8
Li Yang selected 0.5-inch wide tapes and adopted parity check to greatly improve data reliability.
The magnetic drum is his masterpiece?1?8
The drum has a diameter of 8 inches, a capacity of millions of bytes, and a rotation speed of 6000 rpm. It's terrifying!
With these two powerful tools, the data throughput capacity of YN-1 will far exceed that of other computers of the same period.
Li Yang drew the structures of the tape drive and the magnetic drum in the blank spaces of the drawing and marked the detailed technical parameters.
At this point, the design of a complete third-generation computer has taken shape.
Li Yang let out a long sigh, stretched, and a relieved smile appeared on his face.
He looked around, his eyes sweeping across the piles of information and drawings on the table, and his thoughts gradually drifted away.
He thought of the era before he traveled through time, the 21st century when personal computers were everywhere and the Internet was accessible in all directions.
Computers at that time were no longer what they used to be.
With the performance of YN-1, I am afraid it cannot even be compared with a mobile phone in the 21st century.
But in this era, in the New Yan Country, its appearance will be epoch-making.
It marks a new era in the computer industry of Xinyan Country and opens up an infinitely bright future.
Li Yang couldn't contain his excitement when he thought about how much impetus this machine would inject into Xinyan Country's cutting-edge scientific research after it was put into use.
He stood up, sorted out the drawings, and carefully put them into a file bag.
Starting from tomorrow, we will enter a new stage - preparation of peripheral hardware.
Cabinets, brackets, cables, power supplies...each one is indispensable and each one needs to be carefully designed.
Li Yang secretly encouraged himself: Although the road to research and development is still long, there is still a long way to go and the future is promising!
He wants to use his own strength to make the computer industry of Xinyan Country stand out from the crowd and attract the attention of the world!
As the night deepens, cicadas chirp outside the window.
Li Yang turned off the desk lamp, lay down quietly, and soon fell asleep.
……
The next morning, Li Yang arrived at the center refreshed.
He couldn't wait to take out the drawings and call a meeting of core members.
"Mr. Zhang, please help me prepare the cabinet and bracket. Use good cold-rolled steel and follow the size shown in the drawing."
"Xiao Liu, you are responsible for the cables. Use the best copper core wires. The signal wires must be shielded, and the power wires must be rated at more than 1000 watts."
"Mr. Zhao, you should design the heat dissipation and dust removal solutions. The temperature inside the cabinet should be kept at 25 degrees and the dust should be controlled below 100 microns.?1?8"
……
Li Yang arranged everything one by one, and everyone rushed to receive the orders.
Seeing that everyone was doing their job well and full of fighting spirit, Li Yang also showed a gratified smile on his face.
In the following days, the center was bustling with activity.
There are busy figures everywhere, the roar of machines and the sound of metal knocking merge into a symphony of progress.
Lao Zhang, along with a few capable assistants, carefully selected the materials, measured the dimensions repeatedly, and soon welded out neat brackets.
Xiao Liu led the electricians to carefully arrange each cable, fearing that there would be no mistakes. The colorful lines were like rainbows, adding a lot of vitality to the workshop.
Even Lao Zhao was extremely busy.
Wearing reading glasses, he repeatedly pondered the drawings, and from time to time he had to climb to the top of the cabinet to check the fans and dust filters.
Everyone was very curious when looking at these uniquely shaped sheet metal parts.
"Mr. Li, what are you doing? It looks like a radio, but not quite."
"That's right, can you please give me a hint? This thing is not a national defense project, right?"
Faced with everyone's surprise and questioning, Li Yang just smiled mysteriously and refused to say more.
He knew that the time was not right and he could not lift the veil of mystery.
In this way, under Li Yang's supervision, the computer's peripheral hardware was finally ready.
At the same time, he was also working intensively on the development of the most critical component - the integrated circuit chip.
Every day, he would shut himself in his little world and concentrate on working on rows of silicon wafers.
Under his control, the mask accurately casts the shadows of each circuit on the silicon wafer, and a flash of ultraviolet light firmly imprints the pattern on it.
Development, etching, doping, oxidation... those complicated processes condense wonderful patterns on the silicon wafer like magic.
Li Yang carefully picked up a chip with tweezers and examined it carefully under a microscope.
The densely packed circuit lines are arranged in an orderly manner, and the transistors stand neatly in a small space, like buildings rising from the silicon plain.
The various chips required for YN-1 were formed one by one in Li Yang's hands.
He first completed the arithmetic logic unit chip, which is the heart of the arithmetic unit.
Thousands of transistors are integrated on a silicon chip the size of a fingernail, which can easily complete 32-bit addition, subtraction, multiplication and division.
Next, the memory chips.
Li Yang spent a lot of effort and finally used the principle of magnetic domain wall movement to make a 1K-bit random access memory on a chip.
The microprogram chip of the controller uses his most proud photolithography technology.
4000 instructions are neatly recorded on a chip the size of a fingernail, and each one corresponds to a specific control action, which is extremely exquisite.
There is also channel control, bus control, and so on, and so many more.
Li Yang played with the chips carefully under the incandescent light, feeling deeply moved.
Although they are small, they embody his countless efforts and ingenuity.
It is also the hope for a nation's rise and a mark of the progress of an era.
Finally, on a sunny afternoon, Li Yang put the last chip into the tray.
Since then, the core components of YN-1 have all been in place.
Next comes the final assembly.
Li Yang did not call others immediately, but embarked on the journey of overcoming difficulties alone.
He got up early and went to bed late every day, working non-stop for more than ten hours.
First, accurately drill mounting holes on the base plate, and then fix the various brackets and back panels one by one.
Then, he carefully inserted the magnetic core memory pieces one by one and connected them with enameled wire as thin as a hair.
Those slender hands moved flexibly inside the narrow chassis, expertly soldering each pin.
Li Yang was so focused that his brows were furrowed, and he could not even hear the noise around him.
He worked hard for two whole days and nights.
Finally, when the last plug was firmly seated, a brand new YN-1 computer stood in front of Li Yang.
At this moment, he had mixed feelings.
After so many days and nights of hard work and so many all-nighters of research, fruitful results finally emerged.
He stared at the huge machine, and his eyes became moist.
……
While Li Yang was fighting day and night, a major event also happened in the courtyard.
Qin Huairu was forced by her mother-in-law Jia Zhang and her husband Jia Dongxu to find a job.
Her family was originally poor, and since she gave birth to the child, they have become so poor that they can barely make ends meet.
The mother and son of the Jia family scolded her all day long for being a "money-loser".
Qin Huairu couldn't bear it anymore and had to come to take over the job.
Early in the morning, she dressed neatly and walked into the gate of the steel mill with a nervous mood.
On the road, she saw a familiar figure from afar.
Isn't that Li Yang?
At this moment, he was full of vigor and energy, and walked towards the laboratory building with big strides, surrounded by a group of engineers. Along the way, those people talked to each other, listening to his endless explanation.
Li Yang answered every question patiently with a confident smile on his face.
The dashing heroic posture and the admirable bearing made Qin Huairu a little dazed.
A trace of sadness rose in her heart.
Once upon a time, she was also the focus of the crowd and was highly sought after.
But now, she can only stare at others and cry secretly in a dark corner.
Thinking of this, Qin Huairu's nose felt sore again.
She quickly wiped away the tears from the corners of her eyes and walked towards the factory office with gritted teeth.
There, Deputy Factory Director Li Huaide had been waiting for a long time.
He sat behind his desk, with a fat body and a shiny forehead, and looked Qin Huairu up and down with malicious eyes.
"Comrade Xiao Qin, you just applied to come to work? Don't you need to take a rest?" Li Huaide asked in a frivolous tone, crossing his legs.
Qin Huairu blushed and nodded quickly.
She was petite and delicate, with a pair of big watery eyes and a pitiful look, which aroused Li Huaide's animal desires.
He asked Qin Huairu a few more questions.
Qin Huairu answered hesitantly, her voice as soft as a mosquito's.
"Okay, I'll arrange it for you right away." Li Huaide nodded with satisfaction, his eyes lingering on Qin Huairu's graceful figure for a few more times.
Qin Huairu felt as if she had been pardoned, and hurriedly said goodbye and left.
However, she didn't know that a huge trap was waiting for her to step into.
……
One morning a few days later, when the first ray of sunlight shone into the office, Li Yang finally straightened his aching back.
YN-1, the first large-scale third-generation computer in the New Yan Nation, was finally born in his hands!
It is pitch black all over, and its trunk is huge, as big as a washing machine.
The front is covered with large and small instruments and indicator lights, just like the cockpit of a fighter jet.
On the back panel, densely packed interfaces are neatly arranged, serving as a bridge for communication with peripheral devices.
The most eye-catching thing is the nameplate on the top of the cabinet, which is as big as a washbasin.
There are four big characters engraved on it in a flamboyant style: YN-1.
Li Yang stroked every inch of the metal carefully, feeling extremely excited.
He finally completed the mission of this era and established a milestone for the computer industry in New Yan Country.
At this time, the sun was shining brightly, shining through the window lattice and casting mottled light and shadows on the computer chassis.
The body of YN-1 was coated with a layer of gold, shining brightly, like a mighty and extraordinary god.
