Like a shooting star, Cao Changjiu, who created the brilliance of domestic computers, disappeared, and even the wide-ranging academic controversy did not leave his name.

The social development of the transition period was too fast, almost everything changed rapidly, and the emancipation of the mind and the legacy left by the predecessors changed the fate of many people.

Without the harassment of the outside world, with their own team in their hands, they can finally work according to their own steps with peace of mind for a long time.

As expected for a long time, Fujian's program-controlled switch introduction project was delayed, the bait thrown by the Japanese was fragrant, the negotiations were arduous, and the asking price was unreasonable. It's like a trapped shareholder, reassuring himself that everything will be fine.

In fact, the Japanese did play a beautiful karate, invested with Huaxia's money, developed the technology they needed, and turned around and continued to sell to Huaxia, which is simply a classic business success story.

This past was personally told to Cao Changchang by the leader of the General Administration, and there was no second person next to him, looking back on this unbearable past, both of them were embarrassed, but it was too late at that time.

If the domestic computer industry is still proud, it can only count 0521 microcomputers. This high-level industrial product has triggered the last glory of domestic enterprises, not only occupied the State Council and become the royal computer, but also because of its low cost and strong performance, it has eliminated all domestic small computers in almost one year and has become the most widely used computer system.

The 0521 is not only a general-purpose microcomputer, but also derived from many other uses, including single board computers, accounting computers, industrial control machines and various military models.

Complementing 0521 is the long-written system and development language, because 0521 has become the de facto national standard, so the textbooks of the computer department in universities are the unbeatable 0521 computer system analysis and concise language compilation, which has been used as a bible by generations of students.

In the class of the computer department, the general professor will hold these two books in class, and after class, he will recommend a mimeographed manuscript, and on the simple cover is the four big characters of the dragon flying and the phoenix dance - the compilation principle, which is said to be written by the director of the previous generation of computing institutes. As for the author, it is the little-known Cao Changjiu.

It has been unanimously recommended by all professors, and it has almost become an informal textbook, and students naturally follow this compilation principle as if it were a classic, and the content in it is really in-depth.

The origin of this manuscript is also very strange, it was written for a long time when the computing institute equipped the 757 mainframe with a software environment, and it was basically sorted out by Wang, because the words for a long time are really unsightly. Later, 0521 microcomputer became popular, and its RISC architecture was the first in the world, and there was no teaching material in this area in China.

The content of the book is very simple, it is to describe the structure of the compiler, the algorithm and the development direction, the text is simple, almost just give an example and then talk about the solution, not to talk about the simple explanation, but the practicability is very strong, and the list is some practical application problems.

It's just that Wang left early, and this compilation principle was not completed in the end.

Compared with the awkward terms and theories, the students have a very high opinion of the compilation principle, and some people can even memorize the entire compilation principle, which is very beneficial.

Believing in his way and respecting his people, the students are even more interested in this little-known author, and they don't know if they ask the professor, but they only say that they are the author of the 0521 microcomputer, and it is estimated that they are also ancient gods and the like.

After all, the long-term exposure rate is not high, and it will not be able to become a god in two years, and the 0521 microcomputer is also launched by Lishan, so few people know it.

Originally, the 0521 microcomputer was not very famous, even if it had entered Zhongnanhai and entered various factories. It was only a later incident that changed the fate of 0521 and ignited the hope of the national industry.

In 81 years, Geneva held the Universal Computer Expo, and all countries set up booths to show their strength and strive for orders.

Open China is naturally not far behind, and won the opportunity to show this time, but the 757 mainframe did not succeed, and other things could not be used, and the 0521 microcomputer and multi-processor-based workstations became the first choice.

Geneva's computer gala was an invisible war, and there was no such thing as Intel as it is now. There are constant disputes in the computer industry, and generally speaking, the market is still monopolized by small computers, and as for supercomputers, they are not allowed to be exported.

Therefore, all countries are doing their best to deal with customers from all over the world. Huaxia is naturally no exception, although it is not as popular as the Americans, the Japanese are wealthy, and the booth is also decently arranged, so that people can't find anything wrong.

As soon as several microcomputers are placed, there is a special person next to them to explain the purpose and guide the operation, and behind it is a special place to place multi-processor workstations.

The long-designed workstation is not large, and its chassis is just a suitcase, which can definitely be placed on the desktop, with a large-screen TV and printer, and an office can definitely accommodate it.

Foreigners seem to have a soft spot for microcomputers, and they are reluctant to linger in front of the bizarre microcomputer booths in the United States or other countries.

It's just that in this era, microcomputers are not paid much attention, and those who have the ability to consume are enterprise users, who pay more attention to computing power.

But AppleIIIt is very out of the limelight,AppleIIIleast,Cheap,Compact,The software is also very rich,There is more support for videoform, a killer application software,It has achieved a great impact in the United States,$1500The price of a piece without a display is not a big burden for enterprises,In this exhibition, many countries are very interested in this machine,Basically, there is no similar product in that country。

It's just basically, if there is no 0521......

People often think of the Huaxia booth as Japanese, and when they see a few decent microcomputers on this lonely booth, they come up to them and ask wild questions, and the answers they get are often fluent in English.

The state attaches great importance to this exhibition, and the quality of the personnel sent is quite high, and it is normal to know two or three foreign languages, and in principle, it is not to let a foreign friend find his native accent.

Foreigners were surprised by the other party's fluent answers, as well as the Chinese spirit that was neither humble nor arrogant, and they felt even more incredible that there were computers in the mysterious East, and they all said that they wanted to give it a try.

The staff naturally respectfully invited the other party to sit down, stood aside and took the trouble to explain, demonstrating various functions supported by the software.

The 0521 microcomputer, which has been developed for nearly two years, is fully functional and has all the characteristics of a modern microcomputer, involving almost all aspects of industrial control and commercial applications, but some things are not all in English.

What can be used universally is industrial control and text table processing, but this is enough to make those foreigners stunned, and the microcomputers in the venue are completely toy-level except for the Apple II.

Even the Mac machine has shortcomings,That is, the computing performance,The same is the videoformThis kind of spreadsheet,The performance on the Apple machine is obviously not the same level as the 0521,This difference can be seen even with the naked eye,Especially for large-scale data calculations,0521The speed is often more than two to three times that of the Apple machine。

As a result, foreigners' interest in Oriental Microcomputer — as they call it — increased greatly, and all kinds of people quickly gathered in front of the Huaxia booth, and various languages flew around, which greatly increased the pressure on the staff.

To be honest, the team leader has never encountered this situation, so he has to face it with all his spirit, Rao is like this, or tired and coping, and the supply contract signed on the spot alone has reached 7,000 units.

Almost everyone is in good spirits, and finally got a bad breath, Huaxia finally has computers for export, and this is only a part, those Eastern European countries have a soft spot for 0521, and it is only because there is no support for the corresponding language software that they did not buy it in large quantities, which makes the staff feel regretful.

The team leader couldn't help but start fooling foreigners, saying that the multilingual version of the software was under development and would soon be fully available, as long as it took a while.

The front desk is lively enough,The back can't rest,Soon there are sharp-eyed guys who find that the things behind are different,Whether it's the display or the chassis are obviously bigger,Even the software used for the demonstration is not the same。

"What's that? just that big one, what's it for?"

"That's our latest invention, the high-performance computer, known as the minicomputer killer. The staff explained that this is their unanimous voice, and it is necessary to publicize it when it is time to publicize it.

"Can I take a look?"

"Of course, this way, please. ”

The power of multiple processors is very great, but the cost is relatively high, the main component memory has a lot of money, and other peripherals such as hard disks, printers, plotters, etc. are even more expensive, with an average cost of more than 100,000 yuan for a quad CPU system.

However, these investments are worth it, and one of the most popular PDP11 minicomputers costs three or four hundred thousand yuan, and its computing power is far inferior to that of workstations, which lack software.

At present, there are only some special software developed in China, such as a variety of control systems that require precision, as well as mechanical CAD drawing software, large-scale database processing programs, etc., and the exhibition uses the domestic independent research and development of CAD drawing system, which is relatively rough.

Foreigners don't care about these, they are very interested in the graphics system, constantly operating the photoelectric strokes to draw this and that, shouting in their mouths that they are happy, as if they have got a favorite toy.

With a tangible feeling, the foreigner's interest in this workstation has increased greatly, although he is not too satisfied with the software, but he has a perceptual understanding of the performance of the machine, and begins to enter substantive exchanges, such as asking for some parameters and so on.

This staff member is the best because they are trained to operate the machines simply before they come, and they can blurt out these performance parameters.

It's just that these blurted out data frightened foreigners, according to their understanding to achieve this kind of performance is definitely not the big computer in front of them can stumble, that is the performance of a medium-sized computer, placed in the enterprise, at least it is also a departmental host, not to mention that the long-written operating system supports multi-user login, as long as it is interconnected with the workstation as the host, it can completely replace the general old-fashioned mainframe as a central processing machine.

The foreigner didn't believe that there was no way, the staff had already prepared, and the test started on the spot, and a test was carried out according to the command running speed, so that the foreigner could operate it himself.

After some operation, the data came out, which was basically consistent with what the staff said, and the foreigner was shocked and almost couldn't believe his eyes.

The funnier guy even lifted the tablecloth spread on the table to carefully check whether there were any other machines hidden under the table or any cables connected to the larger machines.

That's it for today, and I'll see how it goes to work tomorrow.
