South Africa is not a small number of good things, the Tea Falcon gunship project is one, but limited by time, it seems impossible to take advantage of this project in a short period of time.

Originally, I was going to see the famous G-5/G-6 series of 155mm self-propelled howitzers, after all, this thing is famous, and there are indeed some bright spots in technology.

Moreover, the South African G-6 self-propelled howitzer is also too distinctive, it is the same as the Swedish Archer self-propelled howitzer, dozens of tons of heavy artillery, and it actually uses a wheeled chassis as a vehicle.

That is, South Africa, a desert and desert terrain with flat terrain and hard geology, has space for large-scale use of wheeled chassis.

Let's talk about some practicality, in fact, as early as the beginning of 1982, the domestic military has decided to develop a new 155-mm self-propelled gun on the basis of the imported United Steel Corporation GC-45 type, and decided to use it as the future two-level suppression artillery of the domestic military division.

Since the domestic layout was started as early as 82 years, and there was no obstacle to the introduction of technology, naturally Wang Zhengguo now has no opportunity to blindly participate, in the final analysis, the domestic development progress is only slowed down due to insufficient investment, but there is no problem in technology.

Armsco invested a lot of resources in the Kempton factory, and after investing enough funds, people are now waiting to see when there will be good things, anyway, Wang Zhengguo has seen the modified Mirage 3 engineering verification aircraft take off from the test station several times during his stay in Kempton for more than a week.

According to the introduction of the technical personnel of the Shudu Institute, this is actually a short-term project invested by the South African military, mainly to improve the current Mirage 3 fighters, install new multi-functional fire control radars, avionics, and enrich the options for weapon mounting.

Wang Zhengguo has some rough guesses, this should be the Cheetah fighter project made up by South Africa, as the mid-term magic change of Mirage 3, it has been positioned as a second-generation and a half generation in many places.

The Cheetah fighter in the upper plane can continue to guard the airspace of South Africa after the launch of the South African self-developed fighter project, until around 2010, after the JAS-39 fighter was procured, it was gradually retired.

The Cheetah project is actually very delicate between the South African multi-role fighter under development, on the one hand, to fill the gap in combat effectiveness before the South African program is put into service, and on the other hand, I am afraid that it will play the role of an experimental object.

After all, there is not much difference between the radar, avionics, and weapon systems of the two aircraft, and it can even be said that they are exactly the same.

Perhaps in the foreseeable future, as long as the airframe and aerodynamics of the South African program are completed, the avionics, radar, weapons and other systems that have been tested and integrated on the Cheetah project will be directly installed, and a third-generation multi-role military fighter will be counted.

Judging from the situation on the South African side, although there are still various problems in the South African fighter program, the progress of the people is definitely not slower than that of the country, and even the overall progress is still faintly ahead, after all, there are still some problems with the interception type required by the military of the Republic of China.

......

When I went to South Africa, the northern hemisphere was still the end of summer, and this more than half a month passed, and I got the second Qingcheng engine project from South Africa again, and then I returned to Johannesburg with satisfaction and prepared to leave.

There are not too many materials that need to be brought back to China, a suitcase can be loaded all, and it is good to check it in with the plane, fly from the southern hemisphere to the northern hemisphere, and when you return to Shudu, it has to be autumn, and suddenly, most of the 85 years have passed.

After a long business trip, the first thing to do when I returned to Shudu was to quickly dispose of the backlog of important documents, although each unit of the foundation has special management personnel in charge, but as long as I sit in the office, there are a lot of work problems.

In the document box, a transnational letter from Boston, USA, seemed a little bulging, and Wang Zhengguo naturally felt that it was unusual at the first time, and carefully swung a knife to cut it.

At a glance, it was actually Yan Yuanchao's study in Boston that had a phased result, this guy did not hide his excitement in the letter, there was no way, people directly figured out the initial version of the graphics operating system architecture, should be happy.

"The PC computer industry in the United States is extremely developed, and various models of computers are even more varied, Apple's Apple 2 computer uses a 65C02 processor, which is roughly the same as the Yaoguang 2 computer we expected, and I have developed a graphical operating system based on the hardware foundation of this computer...."

The letter was written in great detail, systematically describing what he had seen and heard during his one-year stay in Boston, and the part about the graphical operating system belonged to the work report, and Wang Zhengguo soon found the operating system installation disk in the envelope.

After a few glances, he couldn't tell anything from his appearance, so he simply threw it aside and read the contents of the letter first.

With the letter in his hand, he stood up and fumbled for the kettle, poured some water into the teacup that he hadn't used for a long time and shook it twice, then filled it with water, and slowly returned to his seat, leaning back in his chair, enjoying himself.

"Heh, this guy is okay! He also fooled the students of Wang An Graduate School to engage in project development, but he is also a talent with strong organizational skills, I really didn't misread the person, the position of the chief engineer of operating system development is really necessary for him. ”

The more I look at this Yan Yuanchao, the more I feel that this guy is quite capable, worthy of being the earliest grandfather-level programmer in the eighties of the Republic, this person is definitely MAX to explode in terms of talent, what a good guy.

After a little admiration in my heart, I continued to turn the first page of the letter.

"The graphics operating system I have developed now is still very simple, but it is also in the process of continuous development, and I found that the potential of this thing is too great, and the future computer operating system must be the world of graphics, and the cumbersome DOS commands will be thrown into the dustbin of history without hesitation, and there will be no possibility of turning over. “

For the advantages of the graphics operating system, if it is only based on Wang Zhengguo's description, Yan Yuanchao will definitely not have such a deep understanding, and only after truly experiencing it can he put himself in his shoes and feel shocked.

"There are not many computer companies engaged in the research of graphics operating systems in the United States, Alto is the first to develop graphics operating systems, and then Perq system, Star system, lisa system, Visi on system, indos system, Macintosh system, and other products are all shining, and there are at least ten kinds of graphics operating systems that can be seen on the market. “

Since he is engaged in the development of cutting-edge technology such as graphics operating systems in the United States, he is naturally very clear about the situation of his peers, and if you want to say that the evaluation of these products, according to Yan Yuanchao, it is called: There is a world of difference from the appearance described by Wang Zhengguo!

When Yan Yuanchao went to Boston, the two had a long consultation behind closed doors, and the key to the graphics operating system: drop-down menus, window overlapping, window minimization and other technologies were all very critical parts, and these technologies were naturally difficult to see in the early graphics operating systems.

Only the graphical operating system developed by Yan Yuanchao in Boston can initially realize someone's genius idea, that is, Wang Zhengguo's previous strict requirements cannot be released in the United States, otherwise, the current graphics operating system field is a different look.

It's just a letter, and naturally it's impossible to explain all the details in place, and after smiling, I just cheered up when I saw the last paragraph about the itinerary.

"Wang An Graduate School here exchange learning has come to an end, last month the domestic training of college students are very good, but I don't have time to continue to delay here, before the end of this year, I will lead the team back to China, just the domestic 65C02 processor has been able to scale production, I will also complete our graphics operating system optimization in the fastest time. “

This return to China must be inevitable, the previous exchange abroad was originally for the graphics operating system preparation, now as long as the operating system project is needed, whether it is to return to China, to stay in the United States, he has to do his best to meet.

Put down the whole stack of letter paper at hand, take a deep breath, a new era is about to begin, but it is more and more expected, after all, this is the only way for the republic to technically recover the disadvantage in the field of PC computers, and now it can only be broken once, and there will be no turning back without hitting the south wall!

Look at the operating system installation disk on the table.,At this time, I suddenly didn't have the expectation when I just opened the letter.,Anyway, it's just an early product.,It's definitely a lot of problems.,I'm afraid I have to look at Yan Yuanchao's works after returning to China in the future.。

After making up his mind, he picked up the installation plate, put it in his pocket and went out to the Yao Optoelectronics subsidiary.

It must be admitted that when the government-level forces organize the construction of large-scale industrial parks, in terms of efficiency, it is really not enough.

Although the main highway in the park is not as stable as the airstrip, the width of the road alone is enough to show the ambition of the designer, with a standard eight-main road design, and even spacious non-motorized lanes and green belts on both sides, leaving plenty of room for future development.

Yaoguang Electronics is the first company to settle in the science and technology park, occupying the best and most spacious land, during which the new plant built overtime has been completed for a period of time, and production equipment is currently being installed, and it is expected to start initial production before the end of the year.

The newly built scientific research center next to it is the first to be put into use, and the product development and testing of Yaoguang Electronics are currently carried out here, which shows the importance of Yaoguang.

Chambers has been working in the land of the Republic for a whole year, and he is now fully adapting to the environment of Shudu, for the development of Yaoguang Electronics, he is looking at it step by step, thinking that Wang An Computer Company back then, the development speed is probably not more than that.

As for Wang Zhengguo's sudden run to South Africa for a summer vacation half a month ago, in fact, he despised him very much in his heart, and he actually ran away after leaving a big mess in China, which made Chambers tired enough.

As soon as he saw the culprit appear this time, his eyes were even on fire, but fortunately, he didn't know the severity, and no matter how angry he was, he had to suppress it.

With a smiling face, he said with a pleasant face: "I heard that your girlfriend is also going with you, I have to say, Wang, you are very good at enjoying life." ”

"People can't all work in this life, and they can't be left behind in life, which is mainly a combination of work and rest. Of course, if I have enough rest, won't I immediately put into work when I come back, look at this, the core technology of our Yaoguang 2 computer project. ”

The palm-sized installation disk is Yan Yuanchao's hard work for a year, but in Chambers's view, this thing is really mediocre, just an installation disk, and it is indeed rare to use software as the core technology of a computer in these years.

In the 80s, the PC computer was in the time of rapid update and iteration of hardware technology, and at this time, almost all the major computer giants focused on hardware upgrades, and they did not invest too much in software development.

I took it, looked at it, and looked at it, which is also the most common floppy disk in IBM, but I don't know what it contains: "This? Okay, let's find a computer to try, let's take a look first." ”

Although Yaoguang Electronics produces its own computers, the performance of Yaoguang 1 is indeed only that, to meet the needs of scientific research centers, in fact, more products imported from the United States, including IBM-PC, Apple's Macintosh workstations, etc.

"Don't be busy, this thing is not available on ordinary computers, it is a graphics operating system specially developed for the 65C02 processor, and the hardware of the IBM-PC system is not compatible. So, have we developed a new computer based on the 65C02 processor, that is, our Yaoguang 2, I remember that Kaiyang Semiconductor should have produced the 65C02, right?"

The time has reached the end of 85 years, when Kaiyang Semiconductor was inspected before, it promised to supply and produce small batches before the end of the year, if there is no problem, there must be some products handed over to Yaoguang.

Originally, I was just going to casually see what was in the floppy drive, but I suddenly heard that it was an operating system, and it had to be a 65C02 processor to drive, which was interesting.

Laughing suddenly, Chambers became more interested in this thing: "New operating system? I remember that the CCDOS system carried on the Yaoguang 1 is very good, it is the only operating system in the world that can display Chinese, is this going to be eliminated?"

"Yaoguang 1 is equipped with CCDOS has not reached the end of its life, but the DOS operating system is not suitable for non-English speaking countries after all, so we have been developing a more convenient graphics operating system, and now the installation disk in your hand is actually the most primitive graphics operating system. ”
