In the 80s and 90s of the last century, there was an interesting social phenomenon in Shanghai, when there were only Sundays off every week, but on Saturday evenings, at long-distance bus stations, train stations or steamship terminals, it was common to see some people waiting to get on the train.

They are usually in their 30s and 60s, dressed in washed, some whitish blue khaki tunics, and neatly carrying leatherette bags in the wind season, and on Sunday evening, they can be seen returning at the same station dock.

On Mondays, however, they returned to work in colleges and universities, research institutes and state-owned enterprises, and on Sundays, they had gone to the suburbs or counties and cities in the Yangtze River Delta to work part-time.

These people all have a tacit secret, but before that era, especially for them, they had mastered the important technology of state-owned enterprises and colleges and universities, and the talents of important technologies could not be easily separated from the system.

At that time, these people went to work as engineers this Sunday in order to earn extra money to subsidize their families, but they saved a large number of small and medium-sized township enterprises and private enterprises.

In later generations, many private enterprises of considerable scale, the first pot of gold was also related to these Sunday engineers, without the support of professional and technical personnel of state-owned enterprises in these colleges and universities, research institutes, and state-owned enterprises, then a large number of private enterprises would not have the possibility of survival and development at all.

Daxing City, where Duan Yun is located, is far away from big cities such as Shanghai and Beijing, where high-tech talents are concentrated, but he does not need talents with too high technology, purely from the perspective of electronic technology, Duan Yun is personally ahead of this era, and the talents he needs are only talents who can help him build factories and train workers.

At present, there are two electronics factories in Daxing City, Daxing Electronics Factory No. 1 and Daxing Electronics Factory No. 2, these two factories are not large, and the total number of employees is less than five or six hundred, mainly to produce electronic components.

Although it is said to be a secondary product, in fact, after screening, most of the electronic components can be used, because of the quality of electronic components, and the need for repair is rare, so far only four speakers have had problems.

Duan Yun bought these electronic components through Li Caitou, who was a regular worker in Daxing Electronics No. 2 Factory, although he was just an ordinary worker, his uncle was the deputy director of the factory, and it was precisely because of this that he continued to ship inferior products from the factory and sell them to Duan Yun.

So Duan Yun was going to contact Li Caitou next, invite him out for a meal, and ask about their second electronics factory.

If you have the ability to train employees and set up factories independently, at least you need talents at the level of workshop directors or chief engineers in the factory.

The leading cadres of state-owned enterprises usually do not divulge the technical secrets of their factories, and the regulations of state-owned enterprises do not allow them to work part-time outside.

But these are not problems, as the so-called heavy reward must have brave men, as long as Duan Yun opens the price high enough, there is no corner that cannot be dug up.

As for the purchase of related equipment, Duan Yun is not in a hurry now, his plan is to wait until mid-October to participate in the Canton Fair, and through negotiations with the technical staff of the electronics factory, formulate a list of equipment to be purchased.

After Duan Yun settled down on the side of the workshop, he drove back home.

Taking advantage of the fact that the factory was not busy during this time, Duan Yun began to study the newly purchased computer at home.

This head computer doesn't have a windows interface, so I can only take the software in Dos.

Due to the lack of text editing software with a graphical interface, the typesetting of the computer can be called frenzied, and all typesetting formats have to enter symbols, and it is quite laborious to use the edited preview.

Even for someone like Duan Yun, who is proficient in computer programming technology, it takes a while to get used to this kind of computer.

The keyboard is a little stiff, in the previous life, Duan Yun keyboard used electrostatic capacitance, and the feel was very soft, and now this IBM computer keyboard is very uncomfortable to use.

In addition, the computer currently has limited capabilities, mainly word processing and spreadsheet processing, as well as CAD and a handjob mini-game.

In this era, CAD software is still relatively primitive and has very limited functions.

In fact, in the 70s of the last century, the cost of small computers declined, and the American industry began to widely use the interdisciplinary drawing system.

In the early 80s, due to the application of PCs, CAD software was able to develop rapidly, and companies specializing in CAD system development appeared.

At that time, versaCAD was a professional CAD company, and the CAD software developed was powerful, but it was not widely used because it was expensive.

At that time, autodesk was a small company with only a few employees, and although the CAD system they developed had limited functions, it was widely used in society because it could be copied for free, and this system was open, so if you were a master of computer technology, you could develop some functions on your own.

Duan Yun's current computer is using this kind of CAD software produced by autodesk.

At present, the gap between the functions of this CAD software is too big compared to the future market, and many functions have not yet been developed, but for now, if Duan Yun wants to use this software to design car radios, there is no problem.

And what made Duan Yun feel very uncomfortable was that this computer didn't have a mouse!

This year, the mouse is still a very rare thing, the early mice are analog mice, need to have an independent power supply, it is very inconvenient to use, and the response sensitivity and positioning accuracy are not ideal, all kinds of disadvantages add up, resulting in not many people are willing to use it.

In fact, the popularity of the mouse in the world only began in 1984 with the birth of the Windows system, and before that, the cursor was moved through the keyboard.

Keyboard moving cursors is acceptable for processing text systems, but for Duan Yun to deal with graphics systems like CAD, it becomes very complicated, and all instructions and coordinates need to be entered and set in advance, which is like a nightmare for people in the future.

But in any case, the computer still has a very huge advantage in data processing and design, Duan Yun only needs to be proficient in relevant instructions and skills, and can efficiently develop design drawings.

In addition, when Duan Yun talked to the deputy sales manager in Xiamen last time, he learned that in fact, there is a software association in China, and there is even a journal "Software" There is a special software association in Beijing, after paying a certain membership fee, the association will mail a journal to members through the post office every month, so that members can learn about the development of computer software in China and the introduction of various newly developed software, and by remitting money to the designated place, you will also buy the software you want, which is something that Duan Yun did not think of before.
