The old-fashioned domestic command instrument uses a small machine, and the memory or something must be mostly magnetic cores, but when it comes to 442, I have a bit of an impression for a long time.

"Sun Gong, didn't you make the anti-aircraft artillery commander in the regimental headquarters warehouse? I remember that it seemed to be using a 442B computer, but unfortunately it was dismantled. ”

"Hehe, I'm really ashamed, it's a half-finished product that used to be young and vigorous. Lao Sun smiled exaggeratedly, as if there were more people who were proud and few people who were ashamed, "Generally, I don't show it to others, imitating the Soviet one." ”

"That's also great, why didn't you do it later. Chang asked.

"The performance is not good, it is too slow, the skilled gunner is much faster than it, and the failure rate is too high to pull out. ”

"Oh. "It's clear for a long time that the core stuff can't stand the bumps, and that's how it should be.

"Let's go, I'll show you where we work. ”

It's so big, this is the first feeling after entering it for a long time, a square space, and many people are walking around in it, busy with their own things.

"Good boy, this looks like a big warehouse, you can put a rocket in it. "Sticking out his tongue for a long time.

"You're really right, it used to be an airplane hangar, a war standby, but now it's zoned to us. Lao Sun took a deep breath, "I feel at ease when I smell here." ”

"What's that?" ”

"Oh, the 12-meter radar antenna, used in aerospace. Lao Sun said with a glance of his eyes.

"Can you use such a big thing on a rocket?" I couldn't figure out how such a big thing could be used in spaceflight.

"I didn't say this thing would go to heaven, hehe. Lao Sun smiled, "The ship's one, the satellite's tracking." ”

"An ocean-going survey ship!" Chang Chang's eyes lit up, "This thing has been developed, what is it for?"

"The above task, you can't say. Lao Sun smiled, "But there is still a problem, it is the computer." ”

"What's wrong with the computer, isn't it enough?"

"It's still the old system used before, and the roadbed is okay, just do a supporting project, but it's ...... on board," Lao Sun sighed, "It is necessary to redesign and optimize to improve the reliability of the equipment as much as possible." ”

"What kind of computer, how fast does it need to be?" "I felt that my stuff seemed to have a place for it.

"The medium-sized one is now using the 200 series, which is currently the best in China, about two million times per second. Lao Sun thought for a while and said, "It's a pity that the task is tight, otherwise your computer will have a chance to go up if it is successful." ”

"Don't be afraid of the task, I have a ready-made one. "I think about it for a long time, it seems that there was a launch vehicle test in 80 years, and an ocean-going survey ship participated for the first time, as if it was called "Yuanwang".

"!!!" said Sun Qi, "Is it a multiprocessor computer?

"It was the General Administration that required the 021 design, so we had to start all over again. Chang Chang explained, "I made a test machine in Hong Kong, the performance is OK, it is no problem to get millions of times per second, the key is that the size is small and power-saving, and it is no problem to put dozens of them on the ship, but the processor is Motorola's." ”

"Really!" Lao Sun was a little surprised, "There is such a good thing, so can you come up with a prototype now, and I will make a report to evaluate it." ”

After thinking for a long time, he said, "As long as there are materials, it can be done in a week." ”

"Okay. Lao Sun nodded, "Do you have any design information?"

"No, but I can write it now. ”

"Okay, hold on. I immediately reported the situation to the above. "Lao Sun turned around and left.

"Wait, what about the fire control computer. Chang Chang hurriedly asked.

"It's important to do this now, that's not in a hurry. This is my table, you make do with it first, and I'll be back in a minute. Lao Sun waved his hand and left.

I couldn't do it for a long time, so I had to lie on the table and take a pen and paper and start recalling the structure of the workstation.

didn't wait long for a reason to come up, and Lao Sun trotted over with someone all the way.

The man had a flat head, gray hair, and the lines on his face were like knife carvings, which reminded people of Ken Takakura, and when he came up, he asked, "Where is it?"

"What's where?" for a long time, it was incomprehensible.

"Something!" the old man glared at for a long time, as if to say something the child was talking about.

"That's what we're good at. Lao Sun hurriedly introduced, "He asked about the computer." ”

"Oh. "Long pointed to his head," here, it hasn't been made yet. ”

Lao Ping was stunned for a moment, full of anger and angry at Chang Changfa, and immediately turned around and yelled at Lao Sun: "Let you go to Beijing to find someone, why did you run back, people?"

Lao Sun pointed at Changjiu embarrassedly: "He is Cao Changjiu." ”

"What the hell are you doing, where did you come from?" the flat-headed director still growled.

The first impression of this handsome old guy for a long time was completely ruined, and the good feeling was gone.

"Who do you say is the little brat?" said Chang Chang angrily, "I only look at your age to be polite to you, why do you talk so much." ”

The flat-headed director stared at Cao Changchang angrily, his eyes were about to erupt with fire, but he suddenly relaxed: "I'm short-tempered, everyone calm down." Old Sun, you tell me everything about it. ”

snorted for a long time and didn't speak, and Lao Sun told the whole story.

"I see. Director Pingtou understood, and laughed, "You are the expert, I thought it was a professor in his seventies and eighties." I'm sorry to be rude, I'm just this stinky temper. ”

"It's nothing, I'm a very upright person, if you have anything to say, don't mind, director. "I still have a little pimple in my heart for a long time, so I have a gun and a stick in my words.

I don't know if I didn't hear it or what, the director laughed and asked, "Lao Sun said that you have ready-made good things, take a look." ”

"There are things, but they're all in Hong Kong. Chang said, "Far water can't save the thirst of the near, it can only be made freshly, and there must be materials." ”

"Oh. The director was slightly disappointed, but when he heard that it could be made freshly, he immediately became happy, "The materials are there, what do you want, you open an order." ”

"This really needs to be prepared. After dragging a piece of paper for a long time, he wrote a large list of brushes and brushes, and handed it to the director, "Let's do so much first, I don't know if it's enough." ”

"......" The old director looked at the list, but he was speechless, handed it to Lao Sun and said, "Old Sun, you go and see if the six have these stocks." ”

"Yes!" Lao Sun stood upright, but left without looking at the list.

The director smiled and said to Chang Chang: "If you have any requirements, we will meet you as long as you need them, this is this computer must be made." ”

"Rest assured, the original prototype is there, and now we're just copying it. "The materials must arrive as soon as possible, I will need them in the next few days, and the drawings will come out immediately." ”

"No problem. The old director wiped his head and said a clueless word, "I didn't expect you to be so young." ”

"Ahh ”

"It's nothing, it's good to be young. The old director said with emotion.
