Back to the Republic of China to be a editor

"You Hong Kong reporters..." Tang Hua choked on the second half of the sentence, feeling inappropriate.By the way, also put down the two-foot-long wrench. "Well, I am the director and deputy director of the Electronics Industry Bureau. Since I am the director, I must be the number one electronic engineer in China, that is, an electrician. The cadres of the GCD are different from what you think. The boss of your "Ta Kung Pao" sits The office takes hundreds of thousands of dollars every year, and it is you reporters who come out to run errands to write codes. And our cadres are not bosses, and like ordinary workers, we also participate in labor.”

……

Tang Hua successfully distorted the interview, from music and movies to exporting values ​​to them.

After Zhou Xuan returned to Guangzhou, Tang Hua's work at the Huawei TV factory was also finished. Next, he was preparing to return to Shanghai from Guangzhou. Several friends had already come from the Soviet Union.

"Lebedev! Andrey!"

When Tang Hua returned to Shanghai and walked into the computer room, Lebedev and Andrei were dismantling a T50 computer inside.

Lebedev and his party have been here for three days.According to Tang Hua's explanation before he left, the Shanghai Institute directly took five people to the research institute, and then the five people walked around the T50 of the computer research institute for two days.

"Tang Hua! This is really great, great," Lebedev hugged a dismantled computing unit in his arms, and opened the outer iron shell. The capacitors on both sides of the queue are clearly visible, "I never thought that a unit could be made like this in Kiev. It can really be produced in an assembly line."

Tang Hua looked at the T50, took out three of the 12 computing units, took out the segment code display of the cabinet and put it on the table, and the circuit board of the upper display component had been removed by Andre and carried it in his arms. The lower storage drawer was also pulled out.

"Hey, this is a machine worth 50 rubles, Davarish." Tang Hua said.

"Oh, really, that's fine," Vladimir Ilyich Andrei quickly replied after hearing what Tang Hua said, "We have studied the computer from top to bottom in the past two days. Here it is for you."

Andre inserted the circuit board into the upper end of the cabinet, skillfully screwed on the screws, closed the cabinet, put the segment display on the cabinet, forced it into the fixing slot, and then screwed on four more screws.Lebedev also re-screwed the cylindrical iron shell of the computing unit, plugged in the small motor of the cooling fan, and then inserted the assembled processing unit into the cabinet.After inserting the three "cannonballs" into the cabinet, and then closing the storage drawer, Lebedje pressed the button to turn it on, and everything was normal.

"Does this computer cost 50 rubles?" Lebedev said. "That does not seem expensive. Considering that the T50 has almost twice the computing power of the MESM and takes up only the space of a large wardrobe, I think you should export a batch of computers to the Soviet Union."

Of course Tang Hua knew that computers should be exported. In fact, Deng Fa had already gone to the Soviet Union on May 5 to bring the goods and broadcast live.

The United States spent $48 to manufacture the world's first computer ENIAC, which is the currency value in 1946.Tang Hua knew better about MESM, the first computer in the Soviet Union. The direct manufacturing cost of MESM was about 90 rubles without counting the fixed investment for the computer project of the Kiev Institute of Electrical Engineering. During the development process, Tang Hua proposed several key points of the computer The component production plant has completed the production system organization, and the estimated mass production cost he wrote in the report is also in the range of 60 to 70 rubles.

In the 50s, the ruble and the dollar had a fixed exchange rate of 4 rubles to the dollar. A computer worth $1 can sweep away all competitors not only in the Soviet Union, but also in the United States and Europe.

The point is, this computer sells for 12.5 US dollars, and 10 US dollars of it is profit.

And for the country, selling one is equivalent to earning 12.5 US dollars in foreign exchange.Because after receiving the foreign exchange, the wages paid to the workers, the cost of purchasing raw materials, and the funds of the factory are all in RMB.Renminbi can be printed by itself.But we really don't know how to print rubles.

The monthly salary of female workers who weave magnetic core memory is equivalent to nearly 10 US dollars.A worker in a woven magnetic core memory in the United States earns a monthly salary of $150.

To manufacture computer processing units, Tang Hua uses workers from elementary school to high school education (literacy + numeracy), who can understand the prompts on the circuit board, insert the correct tube and throw it to the next person on the assembly line. The monthly salary 10 USD.American computers could only be assembled manually by engineers or even designers themselves, and the assembly process involved last-minute, temporary changes to the design drawings.The monthly salary is one thousand to three thousand dollars.

Deng Fa took more than 200 domestic junior technicians to the Soviet Union for training, and when he returned, he brought a group of Soviet senior technicians to work or hold training courses in the heavy industrial areas of Northeast and North China.In addition to more than 200 technicians, Deng Fa also brought a T50 abroad.As a showcase of Chinese industry, it is displayed in the Soviet Children's Palace for Soviet teenagers to visit.

Of course Tang Hua knew that within two weeks, the T50 in the Children's Palace would be occupied by Soviet scientists and engineers.

"Old Lie, you are now the deputy director of the Shanghai Institute, so let's talk about the next stage of work now." Tang Hua said to Lebedev.

"That's great, I'm just waiting to start working on computers in China," Lebedev said. "In the Soviet Union, you said taller, faster, and smaller. I thought it was science fiction literature. Now it's not. No, it's just an engineering goal."

"Eh..." Tang Hua took out a roll of blueprints, "That's right, the future of computers is higher, faster, and smaller. But for now, we want to be a big guy for the time being."

Open the drawing, the first page is the general system sketch, 12 cabinets shaped like T50 are arranged in a big X shape, and the four consoles are divided into two groups, arranged in the upper and lower concave areas of the X shape.Judging from the size of the console, tables and chairs, the footprint of this giant machine is probably not too small compared to the MESM.

"This is TC50. T50 is a general-purpose computer, and TC50 is a supercomputer. My idea is to use the processor of T50 and use the same storage medium as T50."

"So...the computer has become bigger again?" Lebedev asked dumbfoundedly while holding the blueprint.

"The size of general-purpose computers will continue to shrink, but this is a supercomputer, and it should be the first machine of its kind in the world. Its computing power will be fifteen times that of the T50, that is, more than 25 times per second. Not only computing With the improvement of its capabilities, it also has some capabilities that cannot be achieved even if 15 T50s are used at the same time: multiple peripherals, parallel computing, multi-user operating systems, and efficient special computing software.”

Chapter 32, landing tonight!

Back in Shanghai, in addition to finalizing and launching the research and development of the TC50 and T51 computers, Tang Hua had to do two major projects.

First, establish a radar institute.Second, set up the Communication Electronics Institute.

The radar institute listed a rough plan at the beginning of the year. With the completion of the transistorized modification project of the P-3 air warning radar, a radar modification and modification team was initially formed. With this group as the core, the military was expanded and the radar technology research institute was established. .

The Institute of Communication and Electronics has changed its name to the Bureau of Electronics and Information Industry by default because the Bureau of Electronics Industry has added tasks.The prime minister and the chief accountant planned to expand the Bureau of Electronics Industry into the Bureau of Communications and Electronics Industry in April. Of course, Tang Hua interjected during the discussion. The result of the discussion was to change communications to information, which covered a wider range.

What Tang Hua didn't expect was that the first step of the plan-recruiting soldiers and buying horses, encountered difficulties and couldn't recruit people.

It was already June of 1950, and the mechanical and electrical students of Shanghai Jiaotong University and Tongji University had been exhausted. They searched the campus, only to find some juniors and seniors shivering in the corner.People who haven't graduated can't help them grow.This means that it will take half a year at the earliest before a new batch of graduates can come for internships, and it will take a year for new graduates to be recruited.This is more embarrassing.

There are only a small number of college students in the country, and most of them are literature, history, philosophy, law and businessmen, and they are worried about death.Beijing, Shanghai, Guangzhou, and the three first-tier cities in China are all like this. It is conceivable how scarce highly educated talents are in the country.Tang Hua used to read history books about how backward the government's education was, but now he has an intuitive feeling.

The problem of talents cannot be solved for the time being. With the current number of students in SJTU and Tongji, the group of students graduating next year may not be enough.Tang Hua had no choice but to change the plan. The Communication Electronics Institute, like the Computer Institute, was also divided into two, the Beijing Communication Electronics Institute and the Shanghai Communication Electronics Institute.Let’s first set up a radar technology research institute in Hangzhou, Shanghai Communication Electronics Institute to set up a shelf for the time being, Beijing Communication Electronics Institute is also established, Beijing can always find a few students.In addition to Tsinghua University and Peking University, the Yan'an Academy of Natural Sciences has also moved to Beijing. This is what I have taught in Yan'an.

After finishing these tasks, I almost have to go to Beijing. In early June, the Third Plenary Session of the Seventh Central Committee was completed, and in mid-June was the second session of the first CPPCC National Committee.Moreover, if Tang Hua's predictions are correct, the battle to liberate Penghu will start around this time.

In Tang Hua's eyes, the second meeting of the National Committee of the Chinese People's Political Consultative Conference was neither Xiong Kewu and Dan Maoxin, two old members of the League, who were specially invited to attend, nor was it Chen Shaokuan's first appearance, nor was it Hua Luogenghua's old man—he I have seen Hua Lao.

What Tang Hua wanted to see was Erlei's grandfather, Minister Wang of the Communications Department of the People's Revolutionary Military Commission (formerly the General Administration of Telecommunications of the Military Commission).

On June 6, when the meeting was adjourned at noon, Minister Wang, who was reporting to the CPPCC, received an item from the staff in his seat.

"Minister Wang, this is given to you by Vice Minister Tang Hua of the Ministry of Heavy Industry. He is in the second-to-last row from the right seat."

Minister Wang first picked up a card with words: "Trial-manufactured by the Bureau of Electronics and Information Industry, portable radio walkie-talkie."

Minister Wang immediately dropped the card and picked up the black box on the table.

Our army seized a lot of American-made communication equipment in the War of Liberation. Minister Wang also saw the walkie-talkie.The walkie-talkie technology equipped by the national army is quite good, basically the same as that of the US military.One is the SCR300, which is a 16-kilogram backpack with a 1.5-meter-long antenna protruding from the bag.One is the SCR-536, which is quite small, less than 3 kilograms, and even made into the shape of a telephone receiver, which can be raised to the ear to speak with one hand.The problem is that the effective communication distance of SCR-536 is three to five kilometers, but the communication distance of SCR300 in plain areas can exceed [-] kilometers.

The black box in Minister Wang's hand weighs only about one kilogram, and its volume is less than a quarter of that of SCR-536. It is very convenient to hold in his hand.Minister Wang looked at the walkie-talkie for a while, saw a short antenna on the top of the box, and subconsciously stretched out his hand to pull it. The antenna was pulled out half a meter long like SCR-536.

The walkie-talkie is turned on, and the voice comes from the microphone at this time.Minister Wang put the walkie-talkie to his ear, and it was Tang Hua's voice.

"Minister Wang, the maximum communication distance of this walkie-talkie is 40 kilometers. We are now less than 100 meters away. We can talk normally without pulling out the antenna."

"Oh! Comrade Vice Minister Tang, you are too powerful. No, the communication distance of this walkie-talkie can reach 40 kilometers?"

"The maximum communication distance is 40 kilometers in the plains, and 20 kilometers in the mountains. I see that your report is over, and I'm bored in this meeting. Why don't we skip the meeting in the afternoon and go out to test?"

After such a discussion on the walkie-talkie, the two reached a consensus to skip the meeting in the afternoon.

At one o'clock in the afternoon, Tang Hua and Minister Wang drove out of Xizhimen in a jeep at the northwest corner of Beijing. Minister Wang walked towards Badaling Great Wall, and Tang Hua walked towards Lugou Bridge.

"I'm in Yuyuantan now, where have you been?" Tang Hua asked on the intercom.

"I'm in the Old Summer Palace..." Minister Wang opened the military map and skillfully drew the distance, "The distance is 11 kilometers..."

"I should have arrived at Yuegezhuang, where have you been?"

"I'm in Huilongguan..." Minister Wang measured the distance on the map again, "It's 20 kilometers away! It's 20 kilometers away!"

"Don't get excited Minister Wang, don't get excited, let's keep going"

Finally, after running for almost two hours on the road, Tang Hua arrived at Wanping City, and Minister Wang's car drove to Changping County, 40 kilometers away, and the quality of their intercom conversations was still clear.

Minister Wang was wearing the communication vest given by Tang Hua. The large pocket on the left side of the vest was just enough to insert the walkie-talkie, and the direction of inserting the walkie-talkie avoided the neck and head, and the antenna could be inserted in the pocket when it was turned on.On the right side of the vest is a row of small pockets, which can hold 4 dry batteries.There are 2 batteries in the walkie-talkie, which can be used for 3 to 5 days.Now Tang Hua and Minister Wang have started talking on the walkie-talkie about the mass production and equipment of the walkie-talkie.
