Chapter 46 This feeling, love love

In this era, there are very few things related to electricity and with a little bit of technical content.

my country's first teletypewriter was the BD56 mechanical teletypewriter, which was successfully trial-produced in 055 and was produced until the end of the 80s. The total output over 30 years was only more than 3.4 units, with an average of only about 1 units per year.

At that time, teletypewriters were even more precious and were mainly used in the telecommunications department. It was impossible for them to be lost. Every one of them had been repaired and used.

So Gao Zhendong searched until the afternoon, but he didn't find a teletypewriter, let alone an ordinary typewriter.

Lou Xiao'e, on the other hand, was following Gao Zhendong around with great interest. She showed no sign of impatience at all. Instead, she seemed to find it quite fun.

Seeing Gao Zhendong searching for something but still not finding what he wanted, Lou Xiaoe felt a little sorry for him and asked him, "Zhendong, what are you looking for? Tell me, maybe I know. I'm from Old Sijiu City."

Gao Zhendong organized his words and told her what he was looking for in the simplest and clearest way possible.

Lou Xiao'e thought for a while, her eyes sparkling: "I don't know what teletypewriter you are talking about, but I have an ordinary typewriter at home. My father used to be his secretary, but later my father didn't need a secretary anymore, so he just left it at home and didn't use it. Can you see if you can use it?"

Gao Zhendong thought about it and realized that there was a way!
You can modify an ordinary typewriter yourself. When each key is pressed, a contact will be turned on. Then, you can use a 3-8 decoder built with transistors and the keyboard scanning circuit commonly used in the past to assemble a keyboard.

Although an ordinary typewriter has far fewer keys than the ordinary keyboards used in previous lives, it is basically sufficient as long as the programming is mainly done with English letters and numbers.

You have to modify the circuit part yourself. If you are not familiar with the mechanical part, that's easy. Master Yi Zhonghai in the yard is an eighth-level fitter and he is no joke. As long as you tell him the requirements, he can easily perform such simple mechanical modification.

However, if this is done, the mechanical connection of the typing part will be completely destroyed, so it seems that we have to find another solution.

Gao Zhendong was overjoyed when he thought of this. He held Lou Xiao'e's hand and shook it vigorously a few times: "Xiao'e, you have helped me a lot, haha."

Lou Xiao'e blushed, but she didn't pull her hand away. She was concerned about another question: "You can type the words into the computer you mentioned, but what about the output you mentioned?"

Gao Zhendong had just thought about this problem. He planned to see if he could make a TV, convert the output signal of the transistor computer, and connect it directly to the TV.

At this time, televisions were already available in China. On March 1958, 3, the 17-type 712-cm black-and-white television was produced at Factory 820 in the neighboring city.

Although the definition of televisions at that time was not high, with only about 400 lines, which is roughly equivalent to a resolution of 320*240, but again, as long as it is used for pure computing, this is not a problem.

But it's still the same old problem. This thing is not easy to find. If it doesn't work, finding a TV cathode ray tube (CRT tube) is also a solution.

Even taking a step back, you can get an oscilloscope or a picture tube of an oscilloscope. In his previous life, Gao Zhendong had tried to turn on the XY trigger mode on an old oscilloscope, and then control the output of simple characters and graphics, which was enough for use.

In fact, there is a TV in the system, which comes from the supermarket where I worked in my previous life, but the old problem cannot be solved, the source.

The 712 Factory mentioned above had an initial production cost of over a thousand yuan, but the selling price was cheap. Regardless of profit or loss, the set selling price was 430 yuan. By 1970, the total output was more than 3.9 units, with an average of more than 3000 units per year. You can imagine how difficult it was to buy one.

Gao Zhendong thought, if it really doesn't work, he can shamelessly ask Lao Chen and the teacher to help him get a TV ticket. If it doesn't work, he can consider asking the system. Gao Zhendong didn't hide anything. He told Lou Xiaoe everything except the part that he couldn't say, just as if they were chatting.

Lou Xiao'e listened with great interest. She didn't understand a lot of things, but in her opinion, when Gao Zhendong talked about these things, his whole body seemed to be glowing.

After hearing this, Lou Xiaoe laughed: "Zhendong, I have a TV at home~~~~."

Gao Zhendong thought about it and agreed. As the former major shareholder of the Third Rolling Mill, the neighboring city produces this kind of machine, and it has been in production for more than a year. It is not surprising that her family has one, and it may even be imported.

However, Gao Zhendong did not agree to this matter. This thing was different in nature from the abandoned typewriter, so it was a bit too much.

Seeing that Gao Zhendong didn't respond, Lou Xiao'e's face changed a little: "Zhendong, you should know that my family background is a bit high. Is this what you care about?"

This was a bit of a showdown. Gao Zhendong smiled and grabbed Lou Xiaoe's hand: "You think too much. I knew from the beginning that your family background was high. How low could the class background be for someone who could accurately place the needle at the beginning of the second movement of Dvorak's "From the New World"?"

Gao Zhendong found an excuse for his foresight and continued, "I don't care about that thing. Since you've said this, Xiao'e, I won't beat around the bush. If you want to be with me, then we can be together. I will also try my best to handle your family's affairs better. I have some ideas and methods, but I have to take it step by step to see if it can be realized."

Lou Xiao'e raised her head and said, "Then why are you not interested in my TV? Isn't it very important to you?"

Gao Zhendong patted her hands and said, "This thing is a bit too valuable. If I take it so easily, its nature will change. I will think of other ways first, but I can promise that if I really can't think of a way, I will ask you, okay? Don't worry, business is the most important thing, I won't lose face."

When Lou Xiao'e heard Gao Zhendong say this, she was happy: "Then it's a deal!"

Gao Zhendong nodded: "It's a deal!"

Lou Xiao'e looked at her watch with a smile: "Then I'll ask someone to send the typewriter to you tomorrow night. Now that everything is done, let's find a place to eat. We can just eat whatever we want at noon. Are you starving to death?"

The typewriter has long legs and flew over by itself. Is this what it feels like to be a gigolo? Gao Zhendong loves it.

Gao Zhendong shook his head: "No, I have an appointment with a friend to have dinner at his house today, you can come with me."

This means he is going to introduce me to his friends. Lou Xiaoe was very happy: "It would be bad for me to go to his house empty-handed. Let's go buy some gifts."

Gao Zhendong told Lou Xiaoe that there was no need to buy it, as they were family and there was no need to be so particular.

However, Lou Xiao'e still insisted on bringing a gift. In her opinion, this was very important. Gao Zhendong's close relationship with his friends did not mean that she could be rude.

Gao Zhendong also understood her thoughts. Seeing that she insisted, he followed her idea. The two bought some gifts and walked towards Wang Dezhuo's house.
