Siheyuan starts from the stationmaster

Dingtian Company originally had a design plan for the separation of the keyboard and the chassis, and now it just happens to take it back, otherwise if it is really going to redesign, it will delay at least half a month!

This is because Bai Zirui knows the development trend of computers in the future. The computer research and development team at Dingtian Company's Xiangjiang headquarters followed his design ideas from the very beginning, adopting a vertical chassis design with the keyboard separated from the chassis.

After the Acorn company was acquired by Dingtian Company, Chris Curry merged the Xiangjiang team and John Guo’s Acorn team. Faced with two different solutions, he chose the former Acorn team in the atom computer, using The chassis and keyboard integration design scheme.

This is also the current popular design scheme. Apple's Apple machine, Commodore's vic-20, etc., almost mainstream personal computers that are popular in the market now, all adopt this integrated design idea.The reason for this is also very simple-cost!
The cost of raw materials for the separate design of the keyboard and the chassis is definitely higher than that of the integrated design.In fact, the reason why Chris Curry chose the integrated design solution is because of the cost.Switching to a separate design costs a dozen dollars more per computer, and that extra dozen can be turned into a profit.

The left side of the chassis is a detachable movable panel. Chris Curry removed the movable panel of a main chassis, and the mainboard was fixed upright on the right side of the chassis. Huge cooling space.

The current CPU frequency is still very low, and the heat dissipation problem is not prominent. There is no necessary cooling fan next to the CPU, which is something that only began to exist in the era of Intel Pentium processors.

Chris Curry sighed and said: "Bai Sheng, the vertical design of the chassis is indeed a very good invention. The heat dissipation function of our abc computer has been significantly improved!"

He and Aikang's team were all at Xiangjiang headquarters during this time, making final improvements for the abc computer.Chris Curry put the movable board back on the chassis. In fact, if you look carefully, you will find that there are some thin holes in the middle area of ​​the movable board. This area just corresponds to the position of the CPU in the chassis. In order to accelerate the air circulation and enhance the heat dissipation effect, the detailed design is carried out.

Bai Zirui asked, "Curry, is there any other problem with our computer?"

Chris Curry replied: "The video output needs to be further improved! Our initial design uses a pal mixed video output mode, and now we need to design an ntsc mixed video mode."

The abc computer adopts the mixed video mode, so that the TV set in the individual user's home can also be connected to the computer as a monitor, which can save many consumers the cost of buying a monitor.

The TV systems of Pretty Country and John Country are not the same. Both John Country and Xiangjiang use the pal system, while the Pretty Country uses the ntsc system. Therefore, the version of the abc computer sold in the Pretty Country must make certain adjustments to the video output Revise.

In addition to the video output, some other firmware needs to be modified in the same way.For example, the power supply, the voltage of John's country is 230v, and the voltage of beautiful country is 110v.

Generally speaking, the performance of the abc computer in the stereotype test is basically satisfactory. Except for the initial heat dissipation problem, the others are minor faults in some details, and it is not difficult to improve it.

According to Dingtian's plan, this abc computer will start trial production in mid-to-late August, and it will be officially launched in the markets of Pretty Country and John Country in early September, and then it will further develop versions suitable for other languages.

Xu Zhihao handed a plan to Bai Zirui, and said, "Bai Sheng, this is the operation department's production arrangement plan for abc computer, please take a look at it!"

As Bai Zirui's family business became more and more prosperous, perhaps he didn't realize it himself, but his aura in the eyes of others was getting stronger and stronger, so that people could ignore his real age.

When Bai Zirui first heard others respectfully call him "Bai Sheng", he still felt a little awkward. He felt like he was called an old man in his 60s or [-]s, and he couldn't tell others not to call him that. I am old.

As more and more people call him "Bai Sheng", he has gotten used to it.This is everyone's respectful title for him starting from scratch and creating such a large foundation alone.

Bai Zirui took a quick look at the general content of the plan, and he also made a general understanding so that he knew it well, and would not intervene in these matters in detail.He has always firmly believed that professional matters should be handled by professional talents.

In late July, Pasadena is a medium-sized satellite city 7 kilometers northeast of Los Angeles in the beautiful country of California. There are highways and subways connecting the urban area and nearby communities, making travel very convenient.

Founded in 1873, Pasadena covers an area of ​​60 square kilometers and has a total of 133 residents. According to the estimation of urban development by the Ministry of Finance of the Beautiful Country, the population of Pasadena is about 836.

Pasadena is famous in the beautiful country because of the influence of the annual New Year's Day Rose Parade and Rose Bowl game.The Rose Parade has been held since the first session in 1890, and it has never been interrupted for nearly 100 years.

The Rose Bowl is the oldest bowl game among the "Four Big Bowls" at the end of the national college football season.Every year, the championship teams of the Big Ten and the Pacific Coast Conference will gather at the Rose Bowl Stadium in Pasadena on New Year's Day. Through the broadcast on CBS TV, they will present a battle of dragons and tigers to fans all over the beautiful country.

For people outside the beautiful country, the most likely reason for hearing about Pasadena, a small city with a population of only 10,000+, is that the famous Caltech is located here.

There is also a world-renowned TV series "The Big Bang Theory" in later generations. In the play, Leonard and Sheldon, two high-intelligence nerd protagonists, live in Pasadena.

Although it is still summer vacation, the parking lot of Pasadena High School is full of cars, and visitors from time to time walk to the school auditorium under the guidance of the guide.

The stage of the auditorium has been built and decorated as the background of a classroom, but this is not an ordinary classroom, but a special classroom for computer classes.In front of the classroom is a teacher's desk. The desk is divided into five rows and six columns. Thirty students' computer desks are placed neatly. Each of these 31 desks is equipped with a brand new abc computer.

Although the abc computer will not be officially launched for sale until August, Dingtian Company specially rushed to produce a batch of samples in advance.The publicity has officially started, and Dingtian Company has bought the advertising pages of a series of influential electronic and computer periodicals in the country, such as "Popular Electronics", "Radio Electronics Technology", "Computer Enthusiast", "Bit".

In the latest issue of the magazine, full-page or half-page abc computer advertisements can be seen everywhere. Although the abc computer has not yet been launched, it has already started to warm up and build momentum in advance.These are just conventional marketing tactics.
