After successfully achieving mass production of radios, the little princess was not satisfied with this, but continued to embark on a new research and development journey.

Her attention turned to another epoch-making challenge: computers.

To be more precise, it is the first-generation product that is more in line with the current era, the punched paper tape computer.

This is because punched paper tape computers do not require complex chips, circuit boards, or even transistors and vacuum tubes.

It only requires precise mechanical components and ingenious design.

Therefore, in order to better manufacture the various parts of the computer, the little princess built a laboratory directly in Ziyun Valley adjacent to the steel plant.

Then I immersed myself in it and began my journey of replicating the punched paper tape computer from scratch.

That’s right, it’s a replica, because the little princess had already completed the relevant information about the theory of drawing relics in modern times.

After returning to the Tang Dynasty, she only needed to follow the drawings step by step to manufacture the designed punched paper tape computer.

First, she used her superb drawing skills to draw out the various parts that had long been in her mind.

He began to instruct the craftsmen to manufacture the various components of the computer precisely according to the drawings.

Although these parts do not require electronic components, they require extremely high precision. Any carelessness may cause problems in the operation of the entire computer.

Therefore, the little princess often personally supervises the manufacturing process to ensure that every step strictly meets the design requirements.

Whenever we encounter a difficult problem, she will patiently guide us and work together to find a solution.

"The shape of this part is too complicated. We tried many times, but the precision still does not meet the requirements." said a craftsman with a bitter face.

The little princess looked at the parts carefully, then encouraged: "It's okay, let's try again together.

Perhaps we can adjust the angle of the tool or improve the machining method.”

After repeated attempts and improvements, the craftsmen gradually found the feeling.

As precise components were produced in their hands, a satisfied smile appeared on the little princess's face.

Finally, it was time for the final assembly. The little princess and the craftsmen carefully put the various parts together.

Every debugging makes their heart beat faster, but at the same time they are full of anticipation.

When the last component was gently snapped into place, the little princess and the craftsmen held their breath and stared intently at the punched paper tape computer in front of them.

Although it does not have a gorgeous appearance, every detail reveals precision and ingenuity.

This punched paper tape computer has a simple and exquisite appearance, without too much decoration, but exudes a sense of technology.

Its main structure is made of solid metal material, and the surface is finely polished and sprayed to present a calm gray tone.

The various components of the computer are closely connected together to form a harmonious whole, as if every detail is telling of the ingenuity of the craftsmen.

The little princess carefully looked at the computer in front of her, her eyes full of anticipation and pride.

She knew very well that the successful development of this computer would not only represent a major breakthrough in her field of science and technology, but would also bring unprecedented changes to the entire Tang Dynasty.

In order to test the performance of this computer, the little princess specially prepared a series of complex computing tasks.

She expertly encoded these tasks onto punched paper tape, which she then carefully entered into a computer.

As the paper tape slowly moved, the computer began to emit a slight mechanical sound, as if telling of the magical journey it was about to embark on.

The little princess stared nervously at the computer's output device, only to see it begin to tap rhythmically, and rows of precise pinholes gradually appeared on the paper.

As the knocking continued, the little princess became more and more nervous.

She knew that these pinholes represented the computer's calculation results, and each hole was crucial.

She stared at the tape intently, afraid of missing any details.

The pinholes on the paper tape gradually became denser, and the little princess's heartbeat also accelerated.

Finally, the computer stopped working and the paper tape stopped moving.

The little princess couldn't wait to pick up the paper tape and asked the recorder who was ready beside her to carefully check the results.

The recorder quickly read out the results on the tape, and a happy smile immediately appeared on the little princess's face.

All the test results were in perfect agreement with the little princess's expectations.

This punched paper tape computer undoubtedly successfully handled all complex computing tasks.

Afterwards, the little princess further challenged herself with a series of more complicated addition, subtraction, multiplication and division operations.

Each time, the computer gave an impeccable answer with amazing accuracy and efficiency, which made the little princess deeply pleased.

She turned around excitedly and gave a decisive order to the guard captain Li Junxian who had been guarding beside her:

"Li Junxian, quickly report this good news to His Majesty and His Highness Changle. There must be no mistakes!"

Li Junxian took the order and left, while the little princess continued to stay in the laboratory and devote herself to further research and development of transistors.

But it is obvious that developing transistors is a huge project for Datang, an industrial desert.

Datang's industrial base was relatively weak, and many key materials and technologies had not yet been developed.

The first dilemma the little princess faced was the scarcity of materials.

In Datang, high-purity silicon materials were almost impossible to obtain, and silicon was an indispensable element in the manufacture of transistors.

In addition to material problems, technical difficulties also arise one after another.

The manufacture of transistors requires precise control technology, including multiple steps such as doping, oxidation, and metallization, and each step requires extremely high precision and stability.

But in the Tang Dynasty, such technical reserves were almost zero, and everything had to be explored from scratch.

In addition, the little princess also faces the problem of talent shortage.

Although she had some skilled craftsmen around her, they knew almost nothing about high-tech products such as transistors.

Therefore, the little princess not only has to carry out technical research and development, but also has to take on the task of training and guiding the team.

This also means that even if the little princess has obtained detailed production information in modern times, it will take several years or even decades to successfully replicate it in the Tang Dynasty.

But fortunately, the little princess is still young and she can wait.

On the other side, Li Junxian rode his horse at full speed and rushed to the palace to report to Li Shimin the news that the little princess had developed a punched paper tape computer.

"Come in." Li Shimin's calm voice came from Ganlu Palace.

Li Junxian pushed the door open and walked in, kneeling and bowing, saying, "Your Majesty, I have important news to report."

Li Shimin put down the memorial in his hand, looked up at Li Junxian, and raised his eyebrows slightly: "Why are you so flustered?"

"Your Majesty, His Highness Jinyang has successfully developed a punched paper tape computer, and I have been specially ordered to report this to Your Majesty." Li Junxian said excitedly.
