Ye Kai remembered that when he was in college in his previous life, the teacher once told them a sad and helpless thing in the late 70s, that is, when the 16-bit computer in foreign countries was large-scale, we were still struggling with the imitation of the 8-bit computer, and the Ministry of Electronics Industry of the country had analyzed in detail the 8-bit computer with Z80 chip that had drifted into China at that time, and the circuit and system had been drawn and collected successfully, but in the end it was stuck on the most critical CPU chip and had to be stopped.

Because, due to the blockade of the Batumi organization, although these chips can be introduced back in Huaxia through other channels, but the number is not much, most of them have flowed into military enterprises, and only a small part have flowed into scientific research institutes, so for a long time, the vast majority of technicians in Huaxia have no way to start the maintenance of second-hand automatic machine tools controlled by chips, which is understandable.

Moreover, during this period, a small number of 16-bit chip computers worth more than 1,000 US dollars were sold to Huaxia during this period, and they were about 100,000 yuan in our hands, and 8-bit computers worth several hundred dollars were also 4 or 50,000 yuan.

At the same time, the technological blockade of the Chinese mainland by Western countries also includes Hong Kong, which is separated from the mainland by a river. After the mid-70s, the Governor of Hong Kong tried to develop Hong Kong's light industry and electronics industry, and built several industrial zones, but he could not introduce high-tech chips and production lines, and could only produce electronic products that were obsolete by the Japanese: electronic watches, cassette recorders, black-and-white televisions, and other stupid and crude electronic products.

It is precisely because Hong Kong's electronics industry is backed by the mainland that these ugly and crude electronic products are smuggled into the mainland market, which is extremely lacking in light industry and electronics, thus feeding many factories, so that after the reform and opening up, they have strengthened their confidence and determination to move north.

It was precisely because of the foundation laid by the Hong Kong governor that Ye Kai's father believed the words of the real estate tycoon who had disappeared, so he did not hesitate to purchase these chips through his friends in the UK.

Ye Kai looked at the chip in his hand with a toothache, very depressed.

Can you not be depressed?

It's a pit!

A chip of 2 million is almost 15 million when converted into Hong Kong dollars, and what is the chip worth 15 million that is destined to be eliminated and has few applicants in the international market is used for?

Design and produce your own computer?

To know that to form a computer, the CPU alone is not enough, it first needs a circuit board, and then the circuit board also needs other electronic components, such as coprocessors, I/0 integrated circuits, etc., after the computer is assembled, the supporting systems and software do not need to be written by themselves?

Thinking about what he was about to do, Ye Kai reluctantly gave up, he didn't have time at all!

Ye Kai was bored with the chip still on the table, picked up the cigarette case next to him, took out a cigarette and lit it, then took a deep breath, looked at the disassembled TV on the workbench, and decided to put the annoying chip in front of him aside first, and take care of it!

Because, the day of entering the market is not far off, so arrange the things in front of you first!

Ye Kai powered on the TV, connected the antenna, walked out of the work area, picked up the remote control board, first selected automatic search, and automatically recorded the channels searched and stored in the ROM external to the microcontroller.

When the TV automatically searched and stayed on a stable TV screen,Ye Kai knows,This circuit board has been half successful,The next thing that needs to be experimented with is,Select the station and control the volume。

In the following time, Ye Kai tested this circuit board repeatedly, and even moved out the rocking chair dedicated to his old man, half-lying on it comfortably, lit a cigarette, and comfortably smoked while testing the TV with the rough and ugly remote control board, with an indescribable sense of satisfaction and accomplishment in his heart.

I don't know when there are a few people standing behind me to watch the excitement,Because remote control color TV has not yet been popularized in Hong Kong,The price is still relatively expensive for ordinary people,Except for the occasional few in large shopping malls,Basically you can't see it in Yaliao Street,And Ye Kai's father's new electrical appliances are also based on manually tuned color TVs,Supplemented by black and white TVs,So,Occasionally,People passing by,Looking at Ye Kai lying 1 meter away,Use the strange square box in your hand to control the TV feel more novel。

Ye Kai didn't care, are people who open shops and do business still afraid of onlookers? Therefore, it wasn't until a voice came from behind that Ye Kai turned around happily, because someone was finally interested in this.

The voice said, "Did you use the plastic box in your hand to direct the TV?" Do you use ultrasound or infrared? Can I try it? ”

Ye Kai reclined and turned his head, followed the guidance of his ears, and aimed his gaze at the young man among the few people standing behind him, the first thing that caught his eye was a handsome face with a parted head and thick eyebrows and big eyes, and then looked down, the white shirt in the open brown suit was neatly tied in the belt of the suit pants, very spiritual and a little elegant, which made people look at least not offensive at first glance.

Since he saw a person who was not disgusting and might be technological, Ye Kai, who was a tech nerd in his previous life, subconsciously had an interest in chatting, so he stood up and handed the simple remote control box in his hand to the young man, and said: "You're right, it's the TV controlled by this thing, it uses infrared remote control, give it to you." ”

"IR remote control?" The young man carefully took the small plastic box, and under Ye Kai's guidance, he clumsily pressed the buttons on it, watching the working mode of the TV keep changing with his own control, which was very novel and exciting.

After all, he had only known from the school's archives that the Japanese had made the transmitting and receiving devices in infrared remote control technology, but he had never seen the actual circuit of this part, and today he may finally have the opportunity to see the real face.

"You made it yourself?" The young man played with the buttons over and over again, and asked Ye Kaidao, "Can I take a look at the circuit board you made?" ”

Ye Kai nodded, and took the initiative to walk towards the workbench, and a few people next to the young man followed Ye Kai inside.
