Li Sanbiao, a big man, knows the private affairs of the park, has nothing to do with himself. But the wolf is coming.

In Long Kingdom, in fact, in the 1980s, everyone also took AIDS as a foreign joke, and I didn't quite understand the matter. In the 1990s, the wolf really came and started talking about AIDS.

After sentenced to death, his reputation was smelly.

This is not blame for everyone. In the 1980s, AIDS was rendered very well, and was called "century cancer".

The main reason is that it is not only a kind of terminal illness, but also directly crack down on human technology self -confidence!

The entire human beings have never been in a mess like AIDS, and many people do not believe in science and people.

Many foreigners even think that humans were too open in the 1960s and 1970s, so AIDS was a warning and punishment that God gave mankind!

Then there were a lot of best -selling books that reflected and confession, such as AIDS diary, more than the disease -cured books!

At the door of Dongdan Park, Li Sanbiao wrote a big discovery on the spot in the principle of saving people.

"It is reported that a terrible way to spread the disease-AIDS is found abroad. This virus is transmitted to humans by orangutan and belongs to the immune system virus.

"I have AIDS, harm others and harm myself ..."

"According to advanced foreign experience, cocktail therapy can be used for treatment ..."

"Selling blood is harmful to the body, infecting various diseases, and the glory of labor to get rich ..."

Even if you do your best.

After Li Sanbiao posted a small advertisement, he quickly recruited three or four classes. If the machine was not enough, he first recited the formula and took turns.

Although there is no network and did not advertise in the newspaper, Li Sanbiao's training class passed through the word of mouth, one passed ten, ten passes,

What Li Sanbiao didn't expect is that the most most from the young, but the educated youth.

Today's educated youth, that can be used to describe it with no pain.

I feel that I have been delayed, I long for knowledge, and change my destiny through learning!

Li Sanbiao is sympathetic to them. In fact, many people do not know that the four -nine city and the magic capital, as well as the educated youths of major cities are the three major production and construction military regiments,

For so many years for the country, the contribution has not been recognized. The culture is not high, and the college entrance examination has no relationship with them. It is too bitter.

Any crafts start from elementary school, too late in their thirties, simple and easy -to -learn typing is most suitable for them.

Li Sanbiao only collects half of the tuition fee for educated youth. If you are willing to stay, you can learn the assembly computer at your own factory,

Those who have completed their family can also leave a family address. After a few months of the society, the computer is popularized. It is recommended that they go to buy a computer unit and be a computer typist.

There are no computers in society, but it will be available soon, because Li Sanbiao intends to promote.

Who said that the computer must be like the PC? Who said that there must be a hard disk!

If it is only commonly used, even in the 1980s, the computer is not very expensive!

Still, 6502 has a open source chip that has been used for more than 20 years, and it is cheap and good.

Yadali 2600, Apple II machine, Nintendo red and white machine, all of them.

Li Sanbiao changed the telegram translation machine that had just been produced, and it became a learning machine.

Don't look down on the learning machine. The amount of Apple II machine is also a learning machine,

In other words, those who are not open to the source can be called a learning machine.

And the learning machine in our country has a common function of office computers, but it is not equipped with commercial application software!

To say the real learning machine, let's talk about what is going on with the red and white machine.

The structure of red and white machines or learning machines is actually not complicated, that is, a integrated circuit board with peripheral circuit welded on top, that is, some resistors, inductors coils and capacitors. They are generally responsible for input and output, sound playback, memory expansion, etc.

The core of the circuit board is a 6052 CPU. The parts connected to it are prefixed with "P". For example

The sound chip is integrated in the CPU.

It is also an command processor that reads instructions from the command depositor and determines the signal that comes from the operating handle to control the graphic processor to display different pictures and make different sounds.

In addition to the CPU, there is also a graphical processor PPU containing 2K video memory, and related VRAM.

Li Sanbiao sighed that the 2K memory is also shabby. Even if the Apple machine has 16K memory, this Nintendo is really worthy of the Toyo manufacturer.

However, just use this!

Li Sanbiao ordered the three uncle, our learning machine should use 8K memory and 4K video memory!

Of course, you still have to be marked as 1K to the outside! It is called Toyo people to shock!

He knows the characteristics of the Toyo people. Pursuing the ultimate cheap, they will definitely find a way to reduce the memory of Nintendo game console to 1K!

What are the consequences, hey ... Li Sanbiao will laugh when you think about it.

As for whether the Togo people will disassemble their machines, Li Sanbiao is not worried,

Anyway, memory and memory are produced by yourself.

The three uncle said that the most important thing about the game console is this graphic processor, which should be studied well.

"Ding! Nintendo uses Ricoh's PPU, Ricoh 2C02 chip. It works under CPU control and is specifically used to output signals to TV!"

Liu Guangfu understands, this stuff is the display chip integrated on the motherboard!

But unlike the computer, the game console and learning machine use the computer as a display.

The PPU is the graphic information that can be used to store the digital image digital in the graphics memory, convert it into an analog signal, and output from 21.

After the scanning board of the TV, it is converted into a video signal to send it to the fluorescent screen, and the graphic is displayed on the fluorescent screen.

Liu Guangfu said: "Can we produce this ppu?"

The third uncle: "This so -called PPU chip is not difficult, but it has to be designed several types, which is dedicated to a certain type of TV."

"According to different TV modes, PPUs have written different work instructions, designed different peripheral circuits, and written CPU instruction code for our ordinary color TV."

Li Sanbiao did not expect so troublesome. It turned out that there are three color electronic types now.

PAL is referred to as P systems, dragons, Xiangjiang, sunrise, Germans and other countries use this color TV.

NTSC referred to as n systems, the United States, Japan, Treasure Island and other countries used

SECAM is relatively rare.

If you want to sell to the world, there must be three models of the United States and the Soviet Union.

Although Long Kingdom was almost Japanese and China -Japan joint venture color TVs in the 1980s, the format was PAL.
Chapter completed!
