Chapter 301 "Telegraph Digital Communication Machine"

Seeing their surprised expressions, Gao Zhendong explained: "In addition to being a practical single-board computer, this is also equivalent to a prototype of a second-generation computer. Although the specifications are relatively low, the technology used is second-generation computer technology, so it can achieve performance that is basically the same as that of DJS-59 at this scale."

Chief Engineer Feng smiled knowingly: "I see, Director Gao took small steps and made quick progress. His planning was very appropriate, and the intermediate results were not wasted. They are also very useful and good things."

"Take small steps and run fast." Upon hearing this, Gao Zhendong felt that something was moving in his DNA.

As a top expert in the field of communications, there is no doubt that Chief Engineer Feng knows what the "DJS-59" of this scale can do, as communications and information are inseparable.

Dean Dong also seconded the proposal: "Director Gao's second-generation computer development plan is indeed ingenious. This time you called us here, is it to give us this?"

Gao Zhendong nodded: "Yes, President Dong, President Feng, although the production volume of this thing is still very low and cannot compare with DJS-59 because the manufacturing process problem is still being solved, I can provide you with some information first so that you can familiarize yourself with it.

After saying that, he turned around, opened the safe, took out a stack of information from it, and said, "Wait a few days for the computing institute to manufacture the first batch of prototypes according to my design. I will give you two of them, and you can start making related products first."

The two were overjoyed when they heard this. They knew that there would not be much of this new product available for distribution before the production capacity was increased. Not to mention that the Defense Work Committee in the outside system, which Director Gao was most familiar with, would definitely be eyeing it covetously. No one could compete with them for this unit.

I thought that in addition to drawing the pie in the sky, Director Gao could first show them the pie so that they could get familiar with it. But I didn't expect Director Gao to just wave his hand and allocate two units over first. This was really generous of him.

They were not worried that Gao Zhendong would not be able to fulfill his promise. They knew a little about Gao Zhendong's abilities. The leaders of their committee had mentioned him many times and had issued orders several times to cooperate with him in work.

Although the order was given, Director Gao didn't seem to care much about us, and there was no news. I didn't expect that he would make a big surprise as soon as he arrived.

Postal and Communications Commission leader: You are being righteous, right? I changed the telephone line.

Of course this is a joke. If you don't have the conditions, you can't install it even if you want to, and you can't change it even if you want to.

Dean Dong smiled and said, "I said that communications and electronics are inseparable. Director Gao really doesn't treat us as outsiders. It would be disrespectful for us to refuse him."

He had no intention of refusing. What if Director Gao thought they really wanted to promote their style?

Chief Engineer Feng struck while the iron was hot: "Director Gao, in your opinion, what should we do as the first step?"

Gao Zhendong didn't even think about it and said, "Last time, the leaders of your committee thought about using modems and telephone lines to partially replace telegraphs to reduce the cost and price of telegraphs. I think this is a good first step. The technology is mature and basically ready. We just need to integrate it."

Dean Dong and General Manager Feng had heard about this matter: "Yes, I have heard about this matter. This is reliable. Director Gao, can the price of this DJS-60D be lower than that of DJS-59?"

If the price is high, there will still be problems with promotion.

Gao Zhendong smiled and said, "Don't worry, the price will definitely be reduced, and it will be much lower. In fact, the price of this thing is not high now, it's just a problem of component sources, and the quantity is relatively small."

The two of them were relieved when they heard this: "Okay, Director Gao, let's do this!"

Although he was not prepared to intervene directly, Gao Zhendong still made some suggestions.

"Technically, whether it's message transmission equipment, message transmission software, message editing software, etc., they are all ready-made. I will notify the computing institute to hand them over to you later. Your main task is integration, which will actually be quick."

Mr. Feng nodded. "Well, we have used the modem and the supporting software you developed. It is indeed easy to use and does not require major changes. We mainly want to add some peripherals that meet our requirements and those of the Postal Communications Administration. The core does not need to be changed much. By the way, Director Gao, is the programming work of this DJS-60D much different from that of the DJS-59?"

They have quite a few DJS-59 programmers. Although C language is difficult, there are quite a few who can learn it well.

Gao Zhendong smiled and said, "You asked the right question. The instruction sets and architectures of the two are the same. If you use assembly language programming, you should pay attention to the difference between registers and addressing spaces. If you use C language programming, there is basically no difference. You just need to modify some predefined definitions and macros."

Mr. Feng was delighted: "That's great. The differences you mentioned are the same as no differences. There is no learning cost at all."

After the DJS-59 series of technologies appeared, he did not fall behind at all and learned them very well, so he was able to evaluate them immediately. There was nothing he needed to learn again.

After saying that, he also complimented Gao Zhendong: "Director Gao, the C language you developed is really amazing. It has great portability."

Several people discussed it heatedly for a long time. The comrade from the Communications Institute even carefully copied the appearance and wiring of the DJS-60D and drew it exactly.

Although this method seems crude, it is helpful for enhancing familiarity with the equipment and improving perceptual understanding without actually installing the equipment. There are many practical things, and it is better to take a look than to talk about them.

Compared with "here, plug it in here", "connect it to the second 9-pin aviation plug on the left behind the circuit board" is much clearer. Because the first statement must first define the front and back of the circuit board, as well as the "left and right" observation direction, otherwise you may really see what "preventing stupidity but not foolishness, and great force will make miracles happen" means.

A typical example in this regard is that when our troops were "waiting for equipment", they often drew instruments on cardboard boxes and trained while waiting.

It was not until almost noon that the comrades from the Communication Institute left with a full harvest and a satisfied mood. Gao Zhendong invited them to have lunch, but he didn't keep them. They stayed here for a long time because of work needs, but they didn't want to stay until noon to eat for free.

Before leaving, they agreed with Gao Zhendong that they would quickly complete the research application and plan for the "telegraph digital communication device" and send them to Gao Zhendong for his review.

After sending them away, Gao Zhendong devoted himself to designing the rocket engine for individual anti-tank missiles.

Yu Yuncheng is still in Institute 1761. After all, the single crystal furnace is such a big thing, and he has a lot of related finishing work to complete in the institute when he returns, such as distributing cakes in their institute.

Fang Yinghong has gone as an expert to support the technical transformation process mentioned last time.

Liang Faming and Liu Rongguo were burning double platinum-rhodium thermocouples using the information given by Gao Zhendong.

So thinking that there was nothing urgent for the time being, Gao Zhendong could rarely concentrate his energy on one thing.

The next day was Saturday. In addition to the Defense Work Committee and the Postal and Communications Committee, which were confident about the plan, the 60th and th Ministries of Machine Building received many calls from units asking about the DJS-D. It was obvious that many units saw the potential of this thing and wanted to see it first. First come, first served.

This had a great impact on the two ministries, so they simply held a meeting.

All ministries should come together to take a look and listen. As for how to divide it, we will discuss it at the meeting.

The meeting is scheduled for next Wednesday afternoon. It takes time for everyone to gather together, but the requirements for participants are quite strict. Each department is limited to one person, and there are certain requirements for positions and confidentiality levels.

This is also the reason why the meeting was scheduled for next Wednesday afternoon. Qualified people usually need some time to replan and reschedule their work. After all, this is a sudden notice.

Gao Zhendong also received the notice. He is the leader of DJS-60D and must go.

Gao Zhendong, who was returning home from get off work, had just entered the courtyard gate and had not yet entered the hanging flower gate when he discovered that there seemed to be a new neighbor in the back house to the west of the gate, and the house was being cleaned up.

It turns out that there was a neighbor in this back house, but it seems that the neighbor has moved away, perhaps because of a job transfer.

In the TV series, of the row of back houses at the entrance, only the one furthest to the west is clearly stated to be occupied by Yan Jiecheng and Yu Li, while the others are either supporting roles or not mentioned at all.

Now there is a new neighbor, and I don’t know whether it is the implied content of the original drama or my own butterfly wings.

In fact, if there is no other way, no one wants to live in the back house. Firstly, from the original design, people living in the back house have low status. Secondly, the back house faces south and north, and there is no sunlight, which is uncomfortable.

But at that time, there were not so many rules. It was good enough to have a place to live. It was better than the basement where my friends who would move to Beijing in the future would live.

It's true that the Yan family was able to get three western wing rooms in the front yard and a back room for their son. They are actually quite capable.

The new neighbor's back house is facing the hanging flower gate, and people coming in and out can be seen at a glance. You can even see the middle yard through the hall between the front yard and the middle yard. In fact, this is the best place to eat melons.

Gao Zhendong nodded and smiled at his new neighbor who was working, greeted him, and asked casually if he needed help.

The other party smiled and shook his head: "No, thank you, I'm almost done with it."

He looks like an ordinary person, with a very low presence. He speaks with a northern accent, but I don't know where exactly it comes from. Gao Zhendong is not very sensitive to accents, but what is certain is that this person does not match the supporting roles or extras in TV dramas.

However, the TV series did not introduce everyone in the compound, so maybe there is some hidden content.

Thinking of this, Gao Zhendong smiled. He felt like he had discovered a hidden Easter egg. It was quite interesting.

After locking the car and entering the house, Lou Xiaoe brought tea and shared some gossip: "The neighbors in the back house have changed. They seem to be two brothers."
