(ps: It was ten chapters at the beginning, but now it has become 15 chapters, and more and more are added. Today, there are ten thousand changes. Please subscribe for a monthly pass.)
When they heard that it would take a long time to assemble a transistor computer, the netizens in the live broadcast room were immediately discouraged.

[Ah, what is this! 】

[How long will it take. 】

[It's so boring, I can't understand it, I just make it up every day. 】

[Speaking of memory, I know, core board?What is this?I have never heard of the name. 】

[I heard from the anchor just now that it should be something similar to a computer motherboard. 】

[Is there such a thing in a transistor computer? 】

[I don’t know, what does it look like after the anchor made it? 】

[What material is used?silicon?plastic?copper】

[Is there any UP master who will explain the video of the anchor, he is too high-tech, I am already confused. 】

From the physics laboratory to the storage room of the chemistry laboratory, Han Yuan found some materials, including resin, copper, aluminum and so on.

Looking up, he happened to see the barrage of inquiries, and explained with a smile: "The magnetic core board is not the main board of the computer."

"If you want to put it another way, it would be more appropriate to use the silicon substrate of the integrated chip."

"Because it connects transistors in series, it functions similarly to the silicon substrate of a chip, while the motherboard of a computer is connected in series with various components such as the CPU, graphics card, and memory."

"As for the manufacturing material, the main body of the magnetic core board is made of insulating hardened electrical plastic, and then supplemented with copper and aluminum wires as bridges to connect the various transistors."

With the materials, Won enters the chemistry lab.

Make the mold of the magnetic core plate first.

Different transistors vary in shape, size and function.

And it is impossible to install thousands of transistors on the same magnetic core board.

Therefore, after the final molding of each magnetic core board, the size and shape may be different.

In addition, he also needs to consider the thickness of the magnetic core board, so as not to burn through when adding grooves and contacts such as copper, aluminum and tin later.

Having said that, the manufacture of a magnetic core board is much easier than the manufacture of transistors. After thinking about it, Won confirmed the manufacturing information of the first magnetic core board.

Resin can be used to make the mold. Find a wooden board to measure out the position that needs to be hollowed out, then melt the resin and pour it into the groove line, and then put it in cold water to cool and solidify.

After cooling and solidifying, take it out, and there are frames of different sizes.

Use a plasticizer to prepare and harden the electric plastic, then melt it and pour it into the frame of the mold. After condensation and molding, the frame of the mold is removed, and it is polished and smoothed with a lathe.

In this way, a rough magnetic core board base is formed.

After preparing all the required magnetic core board substrates, Han Yuan said: "The rough magnetic core board substrates have been completed. This step is very simple, and everyone will know it."

"But then it's a little more complicated to draw the circuit diagram and draw the slot lines on the core board."

"Before this, I needed to draw the circuit diagram on paper before transferring it to the magnetic core board."

As he spoke, he took out a stack of white paper from the drawer, and then cut it to the corresponding size according to the prepared magnetic core board.

Pens, paper, rulers, erasers, compasses and other drawing tools commonly used by elementary school students are the tools used by Won to draw circuit diagrams this time.

The straight lines represent the grooves that need to be carved on the core plate.

The dots and rectangles drawn one by one represent the positions where contacts need to be connected, and different shapes also represent different types of transistors placed.

After working for more than three hours, the circuit diagram required for the first magnetic core board was finally drawn.

This is still taking such a long time with the knowledge and information in his mind.

If another ordinary person came over, he would not know how to draw a pen, let alone draw a circuit diagram.

After all, the design of circuits has never been a simple matter, even the wiring of ordinary households is also quite complicated.

As for the circuit diagrams designed to computer chips, if you don’t have professional knowledge, you may not even understand them, let alone design them.
Stretching and putting down his pen, Han Yuan showed the successfully drawn circuit diagram to the audience in the live broadcast room.

"This is the first circuit diagram. It is mainly used to arrange signal amplification transistors. Its function is mainly to access the electrical signals in the memory and make judgments."

Hearing this, the audience in the live broadcast room looked curiously at the drawings laid out on the silver-white experimental table.

Numerous branches and dots occupy the entire drawing, like a spider web.

There are some numbers marked on each line, dot, and side of the rectangle. The numbers on the lines look disorganized, but the numbers on the sides of the dots seem to be arranged quickly from zero.

And each dot has three numbers, and it is connected with three branches.

Many viewers are dizzy looking at the dense black lines and drawings, and the numbers on it don't know what they are used for.

【ε=(ο｀*))) Alas, it was another day when I couldn't understand the drawings. 】

[Like a gossip map. 】

[If you can understand this, you probably have to start as a graduate student. 】

[This is called a little more complicated?Anchor, do you have any wrong understanding of a little more complicated? 】

[Graduate students may not be able to, don't forget that this is something in the computer, it is estimated that you have to graduate with a Ph.D. 】

[Good guy, the efficiency of the anchor is really high!From thinking to design to drawing, it only took three hours. 】

[Then you haven't seen the blueprints of the generator drawn by the anchor before, such a complicated stack of blueprints can be done in two hours. 】

【Alien bar (dog head)】

[What do the numbers above mean? 】

After showing the drawings, Han Yuan did not continue to draw the circuit diagrams of other magnetic core boards.

Drawing blueprints is not a small amount of work. Even if he can complete the drawing without any mistakes with his current ability, it will take at least a day or two.

He now needs to manufacture the first magnetic core board according to the drawings, then package the transistors, and then test to confirm that there is no problem before proceeding to the next step.

Although he has enough information about the circuit diagram he has drawn, he still has to test it first.

Otherwise, after spending a few days to manufacture all the circuit diagrams and magnetic core boards, if he finds that they can't be used, he will be cheated by then.

With the drawn circuit diagram and the corresponding magnetic core board, Han Yuan went straight to the two-axis lathe.

In the previous first-level mission, he thought about upgrading the two-axis lathe, but at that time he couldn't change it because he didn't have enough knowledge and information.

After the second level mission started, he didn't have time to care about it.

Fortunately, at present, the two-axis lathe is barely enough, but it will be upgraded sooner or later.

The magnetic core board is fixed on the frame, and different kinds of turning tools are constantly cutting on it, and the hardened electric plastic rolled into filaments is scattered on the frame.

Although it is not difficult to install the drawing to process the magnetic core board, it is time-consuming and labor-intensive to process.

After all, although the two-axis machine tool can control the feed depth, it needs manual adjustments.

However, the depth requirements of the lines on the circuit diagram and the round holes are different, so it is very troublesome to adjust the tool and feed every time a line or a round hole is cut out.

The first magnetic core board was only half processed, and it was already around nine o'clock in the evening.

Glancing at the clock hanging on the wall, Han Yuan stopped what he was doing and stopped the lathe.

It's almost the end of the day, and he still has to save some time for himself to make dinner and record materials.

After saying hello to the audience in the live broadcast room, he downloaded the broadcast.

The next day, after another busy morning, Han Yuan manufactured the first magnetic core board.

The original off-white and extremely flat magnetic core board is now covered with various grooves and holes, in different shades, and some holes are punched through.

After blowing off the dust and doping on the magnetic core board, and cleaning it, Han Yuan carefully inspected the processed material.

After confirming that there were no cracks or other defects due to processing, he came to the physics laboratory with the processed magnetic core board, drawn drawings and previously prepared materials.

According to the drawings, Won took out the transistors corresponding to the function and the number of transistors from the box storing the silicon carbide transistors, saying:
"The core of a transistor computer is a transistor for calculation, but a single transistor cannot form a calculation, so it needs to be combined."

"And the function of the magnetic core board is to connect them in series to form an operation circuit."

"Now that the transistor and the first magnetic core board have been manufactured, I need to assemble a magnetic core board first and then test it. After confirming that there is no problem with the circuit diagram, I will manufacture other magnetic core boards."

While talking, Won started to assemble the materials.

The magnetic core board is fixed on the experimental table to prevent it from moving, and the materials brought over include hair-thin copper wires.

These copper wires are the key materials arranged in the grooves to form the circuit. They are measured and cut according to the numbers on the drawing line, and then placed in the corresponding grooves of the magnetic core board.

Finally, the electric plastic is melted, and the groove where the copper wire has been placed is filled and leveled, which plays the role of insulation and protection.

A group of three copper wires surrounds a rectangular point.

The rectangular point is where the signal amplification transistor is placed. The three copper wires need to confirm the three-pole point before connecting to the corresponding copper wire.

When installing the first signal amplifier transistor, Han Yuan casually added:
"Arranging the transistors on the magnetic core board is a careful job, and the wiring of the three poles must not be mistaken."

He just said a casual sentence, but it aroused the curiosity of the audience in the live broadcast room, asking what would happen if they made a wrong connection.

Seeing the dense barrage, Han Yuan replied with a smile: "Once the connection is wrong, there will be a calculation error, and the transistor will be burned or the entire magnetic core board will be burned."

"It's even possible to burn out an entire transistor computer."

"At that time, my efforts of more than three months will be in vain."

"But there is a solution to this."

As he said that, he showed the transistor that was about to be arranged in his hand at the end.

The audience in the live broadcast room can clearly see two small letters 'b' and 'c' written on both sides of this small transistor.

"The transistors I made are marked with two groups of letters bc, group b corresponds to the base, and group c corresponds to the collector."

"In this way, through the letters, we can naturally judge the two poles of the three levels."

"The rest of the emitters can also be judged naturally, and it will be much more convenient for the access of the magnetic core board."

"This is my solution, otherwise the same transistors are mixed together, and it is impossible to tell which one is the third."

[This method is good, simple and practical. 】

[For me, useless knowledge has increased, and I don't assemble transistors. 】

[This is not useless, ordinary labels can also be used in daily life. 】

[By the way, this anchor is quite careful, specially marking on the transistor. 】

[If he wasn't careful, he would have died long ago (dog head), you don't know how many dangerous objects this anchor has made in the past year. 】

[All kinds of dangerous chemicals, gunpowder, sulfuric acid, nitric acid, ether, all will be killed if you are not careful. 】

[Speaking of this upstairs, I remembered that the first time the anchor built a motor, he almost burned the whole house down. 】

Over time, piece after piece of silicon carbide transistors and copper wires were tapped into the core board.

The functions of transistors are different, and the shapes are naturally different. For example, some signal amplifier transistors are flat, voltage regulator transistors are cylindrical, and constant current transistors are cubic.

These transistors of different shapes look like a miniaturized city after being fixed on the magnetic core board through corresponding holes.

The transistors standing in a row are like tall buildings and houses.

In fact, it is true to say so.

If a magnetic core board is compared to a city.

The copper wires arranged in the magnetic core board are like roads, and the third level is like the traffic lights at the crossroads, which specifically control the entry and exit of electrons.

When the various transistors and wires on the first magnetic core board were all arranged, the time came to night again.

After checking carefully and confirming that there is no missing, unconnected, or wrong wiring, the Korean won turned to the camera.

"It took an afternoon, and the first magnetic core board was finally manufactured. It consists of 31 tungsten signal amplifying transistors, [-] dampers, [-] voltage stabilizing transistors, and nine signal reducing transistors."

"This is a transistor board based on the DCTCL script, which can control the passage of current through the script constraint file designed later."

"Of course, that's for later work."

"Now, I want to test it and test whether it can input and output electrical signals normally."

"If it works, it means the magnetic core board was manufactured successfully. Otherwise, I have to spend a lot of time to check what's wrong with him."

"Hopefully pass it once!"
