As she thought, Gao Miaosi took out a newspaper from her bag and handed it to Zhao Yazhi. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 info Zhao Yazhi glanced at it, already understood, stared at Gao Miaosi with beautiful eyes, and said leisurely: "And then?" ”

Gao Miaosi's beautiful eyes flashed, "Ah Zhi, I'm here to ask you on behalf of my sisters!" Is this handsome guy in the newspaper your 'ordinary' friend? How did he invite Pan Yingzi to be his secretary? What does Pan Yingzi do to remove the scars on her face? What's the inside story? "The fire of gossip is burning.

Zhao Yazhi glanced at her angrily, "How do I know about the ones in the back?" It's all said to be ordinary friends! But the man in the newspaper was really him. ”

Gao Miaosi's face begged, and she said coquettishly: "Ah Zhi, tell me!" I promise not to tell anyone else! If you don't talk about everything, let's talk about how Pan Yingzi got rid of the scars on her face, how? ”

Zhao Yazhi didn't understand her careful thoughts. If he hadn't met Li Lingtian, Zhao Yazhi would have heard the news of Pan Yingzi's recovery of beauty for the first time, and Zhao Yazhi would have been very curious to explore the truth.

Zhao Yazhi spread her hands, "Sisi, I really don't know!" Otherwise, you go and ask Pan Yingzi! ”

Gao Miaosi rolled her eyes and said angrily: "Ah Zhi, you obviously know that I am not familiar with Pan Yingzi!" Don't you really know? ”

"yes!" Zhao Yazhi said this, seeing that Gao Miaosi still looked unconvinced, she didn't say anything more, and turned her head to look at the street scene outside the window.

Gao Miaosi saw Zhao Yazhi like this, and she didn't have the idea of continuing to explore, "Ah Zhi, since you refuse to tell the truth, you have to invite this meal!" As he spoke, a smug smile appeared on his face.

Zhao Yazhi immediately turned her head, stared at Gao Miaosi with beautiful eyes, and then chuckled: "Hehe! All right! Although your reasons are too far-fetched! ”

……

In the afternoon, the curtains in the office of the boss of Galaxy Investment had all been pulled down, blocking the scorching sun.

Li Lingtian was sitting in the boss's chair and quickly flipping through a book on quantum mechanics, stopping to think from time to time. There are many other books on my desk, covering quantum mechanics, computers, wireless communications, artificial intelligence, human neural networks, semiconductors, integrated circuits, computer networks, etc., adding up to hundreds of books. There was something else on the table, a long and rectangular piece of equipment, and I don't know what it was; a bunch of bits and pieces of electronic parts, in large quantities; All that's left is tools such as screwdrivers.

Pan Yingzi sat on the arm of the chair sideways, clasped her hands around her chest, and stared at Li Lingtian, who was concentrating on reading. After Li Lingtian finished reading the book in his hand and put the book on the table, Pan Yingzi said glutinously: "Boss, why do you suddenly like reading such an esoteric and avant-garde scientific work as quantum mechanics?" Do you have any plans for people to buy computers, electronic parts, etc.? When people ask you at noon, you don't tell them! Now that I've read it all, I can tell people!? ”

Li Lingtian looked at Pan Yingzi, who was upright on the side, and said, "Doll, don't be unhappy!" I'll tell you later, or you'll find out later! Have I arranged my visa, plane ticket, etc. to the U.S. with you? ”

When Pan Yingzi heard this, a light smile appeared on her face, "It's arranged!" She was very happy to be alone with Li Lingtian for a while.

After Li Lingtian chatted with Pan Yingzi for a few words, he put his energy into business.

Li Lingtian moved the long rectangular equipment on his desk in front of him and looked at it.

The device in front of him is the computer Pan Yingzi is talking about, Cowherd Star (Altair8800).

"Cowherd Star" is a product of MITS (Micro Instrument and Automatic Measurement System Company) in the United States, which is the world's first microcomputer assembled with a microprocessor and the "originator" of microcomputers.

The inventor of the "Cowherd Star" is Edward Roberts (founder of MITS). In 1974, MITS lost to Texas Instruments in the field of calculators, and Edward Roberts was brought to the brink of bankruptcy, leaving $250,000 in debt.

In desperation, Roberts set his sights on the 8080 microprocessor developed by Intel Corporation, hoping to use it to assemble a computer designed for amateur experimentation to save the company from bankruptcy.

In the end, he finally made the "Cowherd Star"! After some twists and turns, "Cowherd Star" appeared in the American "Popular Electronics" magazine, and the magazine commented that it was "barely a computer!" ”

In a metal box, Roberts packed two integrated circuits, an Intel 8080 microprocessor chip and a memory chip, which initially had a capacity of 256B and was later increased to 4KB. There is neither a keyboard for entering data, nor a "face" that displays the results of the calculation. After plugging in the power supply, the user needs to manually press the 8 switches on the panel to input the binary number "0" or "1" into the machine. After the calculations are completed, several rows of small light bulbs on the panel flicker on and off, indicating the output results as if a warship were signaling with lights.

At that time, all computer companies were dismissive of the "Cowherd Star", a simple machine that was at best used as a toy for college students. If your company wants to use a computer to handle business and get a "Cowherd Star", you will find that it really does not have much use.

The sales of the "Cowherd Star" were not bad, with sales of more than 1,000 units in 1975 and are expected to reach 2,000 units. Although the "Cowherd Star" was just a simple device, it caused a major earthquake. After the advent of Roberts' "Cowherd Star" computer, there was a craze in the United States for computer amateurs to buy parts and assemble microcomputers in their home garages.

Li Lingtian plugged in the power, and after experimenting with the function of "Cowherd Star", he couldn't help but sigh: "It's too rough!" ”

Pan Yingzi also looked at it like a curious baby, and said in a glutinous voice: "Boss, is this thing useful?" Her knowledge of computers was limited to knowing the term.

Li Lingtian nodded and shook his head, "It's useful, but it's not very useful!" Immediately, Li Lingtian began to use a screwdriver to disassemble the shell of the "Cowherd Star", dismantled every part inside, and placed them on the table.

After Li Lingtian was busy for a while, Pan Yingzi handed over the towel and said with some doubts: "Boss, why are you unloading it?" ”

After Li Lingtian wiped his hands, he handed the towel to Pan Yingzi, pinched the Intel8080 microprocessor with his right hand, and said, "It was originally used for research, and it is normal to dismantle it!" "Naturally, the method of his research is not to observe with the naked eye, but to use the divine mind to sense everything in his hand from the macro to the microcosm!

Intel8080 is a processor released by Intel in April 1974, is an 8-bit processor, the main frequency is 2MHz, it integrates 6000 transistors, 290,000 operations per second, has a 16-bit address bus and an eight-bit data bus, contains 7 eight-bit registers, supports 16-bit addressing, and it also contains some input and output ports, which is also a fairly successful design, effectively solving the problem of insufficient memory addressing ability of external devices.
