Chapter 282 Children, You’re Welcome

And the 16-page version is also very interesting, with two specifications: large size and regular size.

大度尺寸比A4略短(210mm×285mm)，国际上用得多；正度尺寸比A4纸小一圈(185mm×260mm)，国内用得多。

So in China, when we say 16k, it means the correct size of 185mm×260mm.

Because this is a domestically developed printer, the paper size is defined as the most commonly used 16K paper. However, according to Gao Zhendong's original design, the Institute of Computing still implemented the function of paper size adjustment, which can print papers of different sizes within a certain range.

Gao Zhendong put the paper into the paper inlet and the paper out light went out.

The staff had already prepared the content to be printed and had entered the printing instructions, and were just waiting for Gao Zhendong to press the enter key.

Gao Zhendong and the people at the Institute of Computing did not change the name of the Enter key when they were working on JP-59, because the name was actually inherited from the typewriter, and it can be said to have an orderly inheritance and clear generations, which is really a big win.

Under everyone's gaze, Gao Zhendong pressed Enter.

After a short wait, the printer began to make a hissing sound, and a piece of white paper was swallowed up. Amid the movement and hitting sounds of the print head, a line of words appeared on the paper.

"Proletarians of the world, unite!"

When Gao Zhendong saw this line of words, he remembered that May Day was approaching.

Everyone applauded and laughed together, and the staff who had been prepared recorded this scene with their cameras.

Next, Gao Zhendong and the people from the Computing Institute tested basic functions such as continuous printing, manual double-sided printing, and fault prompts.

We also replaced the blank ribbon and tried the carbon paper printing and wax paper printing functions.

Gao Zhendong was very pleased to see the wax paper being printed out on the mimeograph machine. 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.

Kids, you’re welcome. This is what Uncle Gao should do.

The only problem is that the computer is a bit expensive. I guess most of my classmates still can’t use it. What 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, if a county education bureau could have a set of these things, plus data transmission technology, the teaching results in advanced areas could soon be popularized to remote areas.

Gao Zhendong is not joking. This is a real need. Without a well-educated basic population, there will be no other development.

After all the test items were completed, Gao Zhendong, Director Li, and Chief Engineer Chi discussed the next steps together.

"We are considering organizing a project completion acceptance and then starting mass production. Director Gao, what do you think?"

Gao Zhendong also thought this idea was feasible. He first solved the problem of whether or not there was one. Although this printer was only half now, strictly speaking the other half of its internal firmware was actually in the DJS-59. However, the most popular printer in China now was the DJS-59, which concealed its compatibility issue.

The next generation of computers planned by Gao Zhendong, whether single-board computers or new medium and large computers, are all continuations of the DJS-59 architecture and instruction set, and there will still be no compatibility issues for printers.

Gao Zhendong nodded: "This is a good idea. This machine has reached a practical level and can be put into use. With this thing, combined with the Chinese character editing environment, the problem of computer office work has been basically solved."

Director Li laughed and said, "I guess not many companies are willing to use this thing for office work, haha."

Gao Zhendong laughed and didn't say much. After all, the situation 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 painstakingly copy the calculation results on the computer monitor, which can also make their work a lot easier."

Gao Zhendong smiled and said, "Whether it is convenient or not, let's not talk about it for now. I have been looking forward to it for a long time. Chief Li, Chief Chi, please prepare one for me. I will ask someone to come and get it."

This thing is quite heavy, so it would be better to ask the factory to send a car to pick it up, as it would be too tiring to carry it by myself. Gao Zhendong had been looking forward to this thing for a long time, so he asked for it directly without any hesitation.

Chief Engineer Chi pointed to a wooden box in the corner and said, "Haha, we've prepared it for you a long time ago. We know you're in a hurry to use it. Do you want us to deliver it to you?"

This thing has an iron shell and is very heavy, so cardboard packaging won't work.

Gao Zhendong thought about it and refused. He had spent quite a long time in the computing institute and knew that they did not have enough vehicles. It would be better for him to do the transportation in his own factory.

Director Li did not insist. They were indeed short of vehicles. Outside of the normal production schedule, some unit, for some unknown reason, applied for an additional batch of DJS-59s, which suddenly increased their production and transportation pressures.

Although the operation center is not responsible for delivering the DJS-59 to the user, it is generally only responsible for delivering it to the train station or airport. Some users will even pick up the goods in person. However, even so, the already stretched transportation capacity is further aggravated.

At this time, deep in the desert, several scientific research leaders were holding a meeting.

"When will the newly requested DJS-59 arrive? Also, the power supply problem needs to be properly resolved."

That's right, the unit that applied for this batch of additional DJS-59s was none other than the Damo unit. Apart from a few units like the Damo unit, it would be wishful thinking for other units to apply for additional DJS-59s.

There isn't a single extra screw on the DJS-59, let alone an extra unit.

The reason why they applied for DJS-59 is very simple.

Firstly, this thing is really useful. With the withdrawal of the northern support experts and the advancement of related work, the demand for computers has become more urgent. The few computers we had before were not enough, so funny, they were not enough at all.

The second reason was something that was not anticipated, or it was an abnormal reason.

Several DJS-59s broke down due to the poor electrical environment there.

When it comes to precision equipment, there are a series of usage regulations and specifications during use, which are mainly to make the best use of the equipment in harsh working environments while ensuring the safety of the equipment.

Moreover, there are more regulations for equipment 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 used in the future and even most ordinary people didn’t know about: head docking or head return, is a typical example.

In the early days of hard disk invention, the operating system was not capable of completing these tasks automatically. Even a small number of operating system programmers did not know that this task needed to be completed.

However, no matter how good the system is, it cannot prevent accidents from happening. This is the case in the desert, where frequent unexpected power outages caused computer damage.

This made the staff, who had already experienced the charm of advanced technology, very uncomfortable. Combined with the already high demand, they simply applied for an additional batch of DJS-59.

"The computing institute is already working overtime to produce it, so it should be ready soon."

"But if the power problem is not solved, new damage will still occur. Computers are valuable and cannot withstand such a tampering."

If Gao Zhendong heard this, he would probably laugh. Soon it will not be so precious anymore.

"But the power supply problem is not easy to solve. Energy is already in short supply. We have already thought of a way to use batteries to ensure normal operation, but the problem now is that there is simply no surplus electricity to feed these batteries."

"Fuel is in short supply. There's nothing we can do about it."

"It would be great if this scorching sun 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 right 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 that cannot be commercialized.

At that time, due to technical and material reasons, the efficiency of solar cells was shockingly low. Unlike the country that later occupied most of the world's photovoltaic production capacity and performed the "horizontal axis compression technology" on the national production capacity dynamic comparison chart, at this time, our photovoltaics were not nothing, but at least very poor.

The first artificial satellite we launched in the early 70s had a design lifespan of 28 days, which meant it would die once the power ran out. The lack of solar cell technology was probably one of the reasons for this.

At this time, a scientist smiled and said, "Not necessarily. I think our technology is showing some promise."

The other scientists looked at him, and he pointed to the news report he had just received on the screen: "Someone has developed a single crystal furnace that can mass-produce high-purity single crystal silicon. Can we do something about it?"

Thanks to Gao Zhendong's encryption algorithm, although we are now far away in the desert and supplies are still inconvenient, the level of information we have is far better than before.

What this scientist sees are daily reports on cutting-edge technological developments coming through encrypted data transmission channels.

The place he pointed to was the single crystal furnace. Although the results from the Chinese Academy of Sciences and the 12th Ministry of Machine Building had not yet come out completely, the 17th Ministry of Machine Building had already reported the general situation to the Defense Work Committee. This place was special.

A scientist who was doing related research was delighted when he heard this: "What's the purity?"

"5 9."

"Five nines? Monocrystalline silicon? That's great, there's 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 relatively higher than that of polycrystalline silicon. Although they cannot manufacture them, they can still design them. In particular, the technology of inefficient foreign solar cells has not been severely blocked.

"Well, this method is feasible. Since we have the technology, we might as well use it. The desert doesn't have much else but lots of sunshine and idle land. These just meet the two major requirements of solar cells and can greatly alleviate our electricity problem."

After discussion, everyone agreed.

In this way, Gao Zhendong's single crystal furnace had not yet been completely completed, but it had already been noticed by the big guys.
