Li Xuan looked at the ABC (AcornBestputer) computer in front of him, which was almost the same in appearance as the desktop computer in his memory. A CRT monitor with a vertical mainframe next to it, an external keyboard on the front of the monitor, and a black cable connected to a dedicated socket at the back of the case.

The only thing missing is a mouse, which is fine if you have to configure it, there is a preset analog interface on the ABC computer. But before the graphical desktop operating system came out, the mouse really didn't play that big of a role. And the mouse is not a new thing, it was invented back in 1963 by Dr. Douglas of Stanford University.

It's a pity that this thing may have some applications in professional graphics processing, but in this era, the ones that can be used for graphics processing are small computers, and the number is very limited. For PCs like ABC, users control the computer directly through guò command input. Therefore, although the mouse has been invented for almost 20 years, it has not been popularized.

The original ABC computer chassis and keyboard are integrated design, which is the latest new design. Because in the finalization test, the ABC computer with the integrated design of the keyboard host will have problems with the heat dissipation of the computer after the continuous working time exceeds ten hours. There is a CPU of a test machine, and even because the heat is not dissipated, the temperature rises too quickly and is damaged.

The sudden heat dissipation problem of the ABC computer is also inseparable from the dual CPU design it uses. In the design of the ABC computer, the main CPU is a 1.2MHz 6502 processor, which is mainly responsible for processing I/O, and a 2HMZ 6502 processor is installed in the expansion interface, which is mainly responsible for running the operating system and various application software.

The computer motherboard loaded with two CPUs is squeezed at the bottom of the horizontal case, and the integrated design keyboard is diagonally above, so that when the two CPUs are running at high speed at the same time, the heat emitted cannot be dissipated in time, causing the CPU temperature to be too high.

"At that time, we touched the keyboard on it, and it was all hot!" Du Wenqiang said to Li Xuan with a smile, "Fortunately, we had a design plan for separating the keyboard and chassis before, and now we just take it again, otherwise if we really redesign, it will be delayed for at least half a month!"

With the aura of rebirth above Li Xuan's head, the computer R&D team of Dongfang Electronics' Hong Kong headquarters started with the design idea according to his requirements, using the keyboard and the chassis to be separated, and the vertical chassis design. However, after merging the Hong Kong team and the UK's iKang team, Currie was faced with two different solutions, but chose the integrated design of the chassis keyboard adopted by the iKang team in the atom computer.

This is also a popular design scheme at present, Apple's Apple machine, Kemodo's VIC-20, etc., almost all popular mainstream personal computers on the market now 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 chassis is definitely higher than that of the all-in-one design. In fact, the reason why Currie finally chose the integrated design solution was because of the cost. Switching to a separate design would cost more than a dozen dollars per computer, which could have been a profit.

The left side of the case is a movable board that can be removed, Curry removed the movable board of a main chassis, and the motherboard was fixed vertically on the right side of the case, leaving a huge space for heat dissipation on the side with the CPU installed on the left side.

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

"Vincent, the vertical design of the case is indeed a very good invention, and the heat dissipation function of our ABC has been significantly improved!" Currie said with a smile, pointing to the case.

He and the Aikang team stayed at the Hong Kong headquarters during this time, making final improvements to the ABC computer. Currie put the movable plate back on the chassis, in fact, if you look closely, you will find that there are some small holes in the middle area of the movable board. In fact, this area, which corresponds to the position of the CPU in the case, is specially designed to accelerate air circulation and enhance the heat dissipation effect.

"Are there any other problems with the computer?" asked Li Xuan.

"The video output needs to be further improved! We started with a PAL hybrid video output mode, and now we need to design an NTSC hybrid video mode!" Currie said with a laugh.

ABC uses a hybrid video model that allows individual users to connect their TVs to computers as monitors, which can save many consumers the cost of buying a monitor.

However, the television system in the United States and the United Kingdom is not the same, the United Kingdom and Hong Kong use the PAL standard, while the United States uses the NTSC system. Therefore, the U.S. sales version of the ABC computer must make certain modifications to the video output.

In addition to the video output, some other firmware also has to be modified in the same way. For example, the voltage of the power supply in the UK is 230V, while the voltage in the US is 110V.

But overall, the ABC computer's performance in the type test is basically satisfactory, except for the initial heat dissipation problem, the others are some minor problems in the details, and it is not difficult to improve.

According to Dongfang Electronics' plan, the ABC computer will start trial production in mid-to-late July, and will be officially launched in the US and UK markets in early August, after which further development of versions suitable for other languages will be considered.

"Li Sheng, this is the production arrangement plan of the ABC computer by the operation department, you can take a look!" He Guoyuan handed the detailed plan to Li Xuan and said.

From the original Xuan Zai, Ah Xuan, to the later Xuan Shao, and then more and more people have changed their names to "Li Sheng" recently. As Li Xuan's family business becomes stronger and stronger, maybe he doesn't feel it, but in the eyes of others, his aura is getting stronger and stronger, which is enough to ignore his real age.

When Li Xuan first heard others respectfully call him "Li Sheng", he felt a little embarrassed. Is it good that Li Jiacheng's kind of uncle is called "Li Sheng"? The age of his body is only 19 years old, and he feels like he is being called 59 years old.

But he can't say that you don't call me that, you call me old. As more and more people call him "Li Sheng", he has become accustomed to it. "Xuan Shao" may still make people have a bad association of the second ancestor, but "Li Sheng" is definitely an honorific title for him who started from scratch and created such a big foundation on his own.

Li Xuan quickly scanned the general content of the plan, and he also made a general understanding, so that he knew in his heart that he would not interfere in these affairs specifically. To be honest, with his management level, running a small factory with more than 100 people is already the limit of his ability. This kind of professional matter, let the professional talent handle it.

"Well, I see!" Li Xuan nodded to He Guoyuan, signaling that he knew.

"Brother Kang, how is the plan on the sales side!"

Li Xuan asked Ye Chengkang next to him about the arrangements for the listing of computers. All the senior executives in the company are much older than Li Xuan, and Li Xuan will call them Brother Kang and Sister Ying more closely. This respect is sometimes more satisfying than giving out tens of thousands of dollars in bonuses.

As for the issue of establishing prestige, as the founder and boss of the company, the entire Dongfang Electronics has grown up rapidly under his own planning, so who else dares to despise him? So he doesn't need to put on a lofty posture to make others surrender to him.
