Chapter 282 Kids, you’re welcome
And the 16-inch size is also very interesting. It comes in two sizes: generous size and regular size.
The large size is slightly shorter than A4 (210mm×285mm) and is widely used internationally; the full size is slightly smaller than A4 paper (185mm×260mm) and is widely used domestically.
So in China, generally speaking, 16 karat refers to the positive size of 185mm×260mm.
Because it is a domestically developed printer, the paper size is defined as the most commonly used 16-inch paper. However, according to Gao Zhendong’s original design, the computing center still implements the function of adjusting the paper size. Print on paper of different sizes within a range.
Gao Zhendong put the paper into the paper input port, and the paper out of paper light went out.
The staff had already prepared the content to be printed, and the printing instructions had been entered, and they were waiting for Gao Zhendong to hit the Enter key.
The name of the Enter key, Gao Zhendong and the people at the Computing Institute did not change it when they were working on JP-59, because this name was actually inherited from the typewriter, which can be called a legacy. The preface and chronology are clear, which really opens the door.
Under everyone’s gaze, Gao Zhendong hit Enter.
After waiting for a while, the printer began to sizzle, and a piece of white paper was swallowed. Amidst the movement and hitting of the print head, a line of words jumped out on the paper.
"Proletarians of the world, unite!"
Seeing these lines, Gao Zhendong remembered that May Day was coming soon.
Everyone applauded and laughed heartily. The staff nearby who had been prepared recorded the scene with their cameras.
Next, Gao Zhendong and people from the computing center tested basic functions such as continuous printing, manual double-sided printing, and fault prompts.
The blank white tape was also replaced and the carbon paper printing and wax paper printing functions were tested.
Seeing the printed wax paper being printed on the mimeograph machine, Gao Zhendong was very pleased. He could now give the children test papers. The teacher did not have to work hard to write on the blackboard, and the students did not have to work hard to copy on paper.
You're welcome, kids, this is what Uncle Gao should do.
The only problem is that computers are a bit expensive. I guess most students still can’t use them. It’s a pity.
No, we need to speed up the popularization of computers. Gao Zhendong suddenly felt that the matter of single-board computers became more urgent. At least, a county's education bureau could have a set of this thing, plus data transmission technology, The teaching results in advanced areas will soon spread to remote areas.
This is really not a joke by Gao Zhendong, this is a real need. Without a well-educated basic population, other development will be impossible.
After all the test items were tested, Gao Zhendong, Director Li and Chief Engineer Chi discussed the next step together.
"Our consideration is to organize a project to be completed and accepted, and then start mass production. Director Gao, what do you mean?"
Gao Zhendong also thinks this idea is acceptable, Let’s solve any problems first. Although there is only half of this printer now, strictly speaking, the other half of its internal firmware is actually in DJS-59. However, the one that is more popular in China now only has DJS-59. This It covers up its compatibility issues.
The next-generation computers planned by Gao Zhendong, whether they are single-board computers or new medium and large computers, are a continuation of the DJS-59 architecture and instruction set, and there are still no compatibility issues for printers. .
Gao Zhendong nodded: "This is a good idea. This machine has reached a practical level and can be widely used. With this thing, combined with the Chinese character editing environment, the problem of computer office work can be basically solved ”
Director Li smiled and said: "There are probably not many companies that are willing to use this thing for office work, haha."
Gao Zhendong laughed and said nothing more. After all, the situation a few decades later is not comparable to the present.
Chief Engineer Chi said: "In short, it will greatly facilitate the work of other comrades. At least they don't have to copy the calculation results arduously on the computer monitor, and it will make them feel a lot more relaxed."
< br>Gao Zhendong smiled and said: "It is inconvenient for other comrades, let alone talking about it. I have been looking forward to it for a long time. Mr. Li Suo and Mr. Chi, prepare one for me. I will ask someone to pick it up."
This It's not light, so it's better to ask the factory to send a truck to pick it up. It's too tiring to move it yourself. Gao Zhendong has been looking forward to this thing for a long time, so he asked for it directly without any politeness.
Chief Engineer Chi pointed to a wooden box in the corner: "Haha, I have prepared it for you a long time ago. I know you are in a hurry to use it. Do you want us to send it to you?"
This thing is made of iron. , heavy and heavy, cardboard packaging is not easy to use.
Gao Zhendong thought for a while and refused. He had stayed in the computing institute for a long time and knew that the computing institute did not have enough cars, so he might as well transport it from his own factory.
Director Li didn’t insist. They were really nervous about the car. Outside of the normal production schedule, for some unknown reason, some unit applied for an extra batch of DJS-59, which slowed down their production. and transportation pressures have suddenly increased.
Although the computing center is not responsible for transporting DJS-59 to users, it is generally only responsible for delivering it to the train station or airport. Some users will even come to pick up the goods in person, but even so, the transportation capacity is already stretched. It also adds insult to injury.
At this time, deep in the desert, several scientific research leaders were having a meeting.
“When will the newly applied DJS-59 arrive? In addition, the power supply problem needs to be solved.”
Yes, the units that applied for this additional batch of DJS-59, It was none other than the other side of the desert. Except for a few units like Desert, other units want to apply for additional DJS-59, which is not to say wishful thinking, but at least it is fanciful.
There is not a single extra screw on the DJS-59, let alone the entire machine.
The reason why they applied for DJS-59 is also very simple.
First of all, this thing is really easy to use. With the withdrawal of northern support experts and the advancement of related work, the need for computers has become more and more urgent. The original few units are ridiculous, not enough, not enough at all. Use it.
The second reason was unexpected, or it was an abnormal reason.
A few DJS-59s died due to the harsh power environment there.
When it comes to precision equipment, there are a series of operating procedures and specifications during use. The main purpose is to use the equipment as well as possible and ensure the safety of the equipment in harsh working environments.
Moreover, there are more equipment regulations these days. Due to technical reasons, many operating steps need to be completed manually.
Many requirements or processes may seem inexplicable in the future, but in this era, they are necessary.
For example, a command that no one will use in the future, and even most ordinary people don't know: head parking or head return, is a typical example.
In the early days of the invention of the hard disk, the operating system did not have the ability to automatically complete these tasks. Even a small number of operating system compilers did not know that this work needed to be completed.
However, no matter how good the system is, it cannot prevent accidents from happening. This is the case over there in the desert, where frequent unexpected power outages cause computer damage.
This made the staff who had already experienced the charm of advanced technology very uncomfortable. Considering the already high demand, they simply applied for an additional batch of DJS-59.
"The computing center is already working overtime and production should be soon."
"But if the power supply problem is not solved, new damage will still be inevitable. Computers are precious, but I can’t stand our torment like this.”
If Gao Zhendong heard this, he would probably laugh, and it would soon become less precious.
“But the problem of power supply is difficult to solve. Energy is already tight. We have already thought of ways to use batteries to ensure normal operation. But the problem now is that there is no surplus electricity to feed these people. Battery.”
"I'm tight on fuel. There's nothing I can do about it."
"It would be great if this poisonous sunlight could be turned into electricity. I would be willing to be exposed to the sun for a few more days."
"Solar cells ? The technology is not very mature now and the efficiency is very low."
Even in the future, the efficiency of solar cells will be less than 30% at most, except for laboratory theoretical technologies such as perovskite.
In this year and year, due to technical and material reasons, the efficiency of solar cells is even more shockingly low. Compared with the solar cell that will account for most of the world's photovoltaic production capacity in the future, it has performed on the national production capacity dynamic comparison chart. Different countries have different "abscissa compression technology". At this time, our photovoltaic industry is not only nothing, but at least nothing.
The first man-made satellite we launched in the early 1970s had a designed lifespan of 28 days, which probably meant it would die when the power ran out. The lack of solar cell technology is probably one of the reasons.
At this time, a scientist smiled and said: "Not necessarily, I think our technology is starting to show some promise."
The other scientists looked at him, and he pointed at the screen that just showed up. The news report received: "Someone has developed a monocrystalline furnace that can mass-produce high-purity monocrystalline silicon. Can we do something about it?"
Thanks to Gao Zhendong's encryption algorithm , although now they are far away in the desert and supplies are still inconvenient, their information is far better than before.
What this scientist saw were daily reports on the development of cutting-edge science and technology transmitted through encrypted data transmission channels.
The place he pointed at was the single crystal furnace. Although the results of the National Academy of Sciences and the 12th Ministry of Machinery have not yet been released, the 17th Ministry of Machinery has informed the National Defense Work Committee of the general situation. This place is special.
Scientists engaged in related research were overjoyed when they heard this: "How pure is it?"
"Five nines."
"Five nines? Monocrystalline silicon? That's too much Well, there is hope. We can design a silicon monocrystalline solar cell and ask them to produce it for us.”
Monocrystalline silicon solar cells are expensive, but their efficiency is higher than polycrystalline silicon. They can't manufacture it, but they can still design it, especially foreign low-efficiency solar cell technology, which is not severely blocked.
"Well, this method can be used. Now that we have this technology, we might as well use it. There is not much else in the desert, but there is a lot of sunshine and a lot of idle land. It just solves the two major work needs of solar cells and can greatly alleviate our problems. Electricity problem.”
After discussion, everyone agreed.
In this way, Gao Zhendong’s monocrystalline furnace has not yet been completely completed, but it is already on the minds of the big guys.
