Chapter 732 Great Harvest

System certification! Absolutely leading!
Gao Zhendong was secretly happy, but then he was not so happy anymore.

What the hell is this super huge cabinet?

There is even a very considerate sentence written on the surface of the cabinet: "The original product capacity specification far exceeds the current actual needs and has no practical significance. The capacity is reduced from 120MB to 64KB."

Gao Zhendong was so angry that he laughed. With the crushing power of future technology, there would be no need to consider technical issues. The capacity alone would be enough to crush current computers.

This should be the actual embodiment of the 700MB hard disk in the 120C, which is realized by magnetic core storage. The biggest problem is that 120MB is too big for today. Gao Zhendong even suspects that if the tape storage is not counted, the total amount of external storage in the country is less than 120MB.

For computers in China today, if the external storage is not magnetic tapes, then it is magnetic cores, which are generally only a few KB, and the top ones are tens of KB. A 120MB hard drive is 120000K. If you divide it, you will know that the capacity of a hard drive is probably more than all the magnetic cores in the country combined.

It seems that the hard disk still doesn't work, but Gao Zhendong is not in a hurry. He knows where the problem is now. Since the extraction has been solidified, he will have enough time to solve this basic technical problem after he gets the CPU, and then raise it again.

Looking at this huge thing, Gao Zhendong shook his head and turned his eyes to another circuit board.

This is the memory stick. Just like the hard drive, 16MB of memory is way too large for current computers.

Therefore, the capacity of this memory stick was compressed to 32k, which was already very large. At that time, the memory of mainstream computers was only a few kB.

This is all thanks to Gao Zhendong for creating C6110.

Fortunately, this time the system did not use C6110 to make up the memory stick. After all, C6110 is a 10μm process, and the best integrated circuit process in the world now is 3μm!

This is why Gao Zhendong was determined to develop the 3μm process conceptually despite the possibility that the technology was not mature.

The system only recognizes whether it exists or not! It doesn’t recognize whether it is good or not!

So this memory stick is very simple, with only 8 chips on it, each chip is 4kB, for a total of 32kB.

In Gao Zhendong's previous life, the first 16Kbit DRAM used a 5μm NMOS process. Gao Zhendong used a 3μm PMOS process. Although the operating frequency could not be too high due to the limitations of the PMOS principle, the capacity was still no problem. The chip provided by the system was a single 32Kbit, or 4KByte.

Seeing this, Gao Zhendong finally became happy. If nothing else, this thing alone is worth it!

Even in the 21st century, RAM chips are still the largest integrated circuit category in terms of shipments.

The single-chip capacity of 4KByte can beat all the current running memories.

Gao Zhendong turned his attention to the display of this thing. There was no other reason, it was just too conspicuous because it was very flat!
But unlike the 700C's color TFT display, this thing is a big head display! CRT.

Based on the current display technology, LCD monitors can only achieve monochrome, and can't even solve monochrome grayscale. If you want to achieve color effects, you can only use CRT monitors.

It seems that for the system, it recognizes a color display rather than an LCD display. After all, function is the most important.

Gao Zhendong shook his head and was about to turn his gaze to something else when he suddenly started and turned his head back.

This thing is flat!!!
Maybe Gao Zhendong in the 21st century didn’t feel much about the fact that CRT monitors are flat and almost skipped it.

But anyone who has experienced the heyday of big-head monitors knows how much easier it is to sell flat-screen or cylindrical CRTs than spherical screens!
Even though this thing may be expensive and cannot be promoted as a monitor in China, it is very enjoyable to use it in one direction.

——Make some changes and sell it as a flat-screen TV!
Isn't this going to blow the whole world away?
Hasn’t this become Zhenxing Electric’s flagship product?
Even if it is produced domestically, the market in the countries of the SCO is not large, and it is difficult to protect the patent in the areas controlled by the Oceania Convention countries. This is determined by innate conditions and there is no solution.

But the case of Zhenxing Electric is different. Just like things like tape recorders, Walkmans, and LED lights, Zhenxing Electric completed patent protection in Hong Kong Island, and then reverse-licensed it to sell in the domestic Economic Assistance Council region, thus killing two birds with one stone.

Otherwise, why do we say that the old man has a broad mind? It’s amazing that he kept this window!

Gao Zhendong clashed his fists and palms, "Oh Yeah!!"

He suppressed his excitement and continued to look down, and saw a scrap - a modem.

This thing is the device on the 700C that is closest to the current technological status. Gao Zhendong read the manual and found it boring. There were no essential changes. If he had to say something, the speed had increased from 1200bps to 2400bps, which was an improvement.

But Gao Zhendong had higher standards and was somewhat uninterested in this thing.

Forget it, no matter how small a sparrow is, it is still meat.

When Gao Zhendong shook his head and looked at the next device which he didn't realize what it was, he suddenly jumped up.

"Fuck! We have all these things, let's send them out!"

The system is very powerful, and the NiMH battery in the 700C was taken out.

This is very interesting. Although NiMH batteries do not exist now, the basic components that make up NiMH batteries do exist! And it is not difficult to manufacture.

Nickel hydroxide, metal oxides, and electrolytes are not difficult, so the system actually made this thing. Although compared with lithium-ion batteries, its energy density is not high, but compared with lead-acid batteries, the energy density of this thing is much higher.

Although it has the problem of high self-discharge rate, it is still very useful in some communication equipment. At least it is better than lead-acid and cadmium-nickel batteries. The most important thing is that it does not have the bad problem of cadmium-nickel batteries - memory effect, or it is not that serious.

Don't underestimate this thing. Early satellites used high-voltage nickel-hydrogen batteries.

Gao Zhendong happily put away the instruction manual of the nickel-metal hydride battery. This thing is quite good.

So far, Gao Zhendong has gained a lot.

4kByte RAM chip.

Flat-screen CRT monitor.

2.4kbps modem.

Nickel Metal Hydride Battery.

Finally, he turned his attention to the ultimate goal of this time - CPU. Isn't it for this thing that he bothered with the 3μm lithography machine?

Gao Zhendong knew that he couldn't make an 80486, as the lowest level of that was 1.5μm CMOS technology, but it shouldn't be a problem to make a lower version. 3μm PMOS is also an integrated circuit.

Read the error-free version at 69shuba! 6=9+shu_ba is the first to publish this novel.

Gao Zhendong carefully read the CPU manual on the computer. Wow, so cool!

It's hard to define what he got in his hands. If I have to say it, it's probably a low-process, 32-bit 80386.

The bit width and instruction set roughly implement the specifications of 80486, but some on-chip functions are those of 80386, and the operating speed is almost at the level of 8086.

To put it simply, this is a low-speed version of the 32-bit 80386!

Judging from the knowledge Gao Zhendong had from his previous life, this is a freak!

But if you put aside the shackles of his previous life and only consider the chip itself, this is a fucking magical artifact!

With an operating frequency of 6.5MHz, 32-bit addressing and 32-bit data width, these two items are enough to defeat all computers. If we can't beat them, we can only compare the size and power consumption.

It can be said that the goal of 10 times that of DJS-59 was exceeded on this chip.

After all, the DJS-59 is just a machine with an 8-bit word length and a frequency of 0.6~0.8Mhz.

Unfortunately, due to the limitation of PMOS switching speed, the upper frequency limit of this thing is only so much, but Gao Zhendong doesn't care.

If he were to design it himself, he knew that it would be impossible for him to achieve this goal, and that only the system could do it itself.

As for this thing, it's no problem to say that it was 1982 years ahead. After all, in 80286, there was only 1.5. Except for the main frequency and μm process, it was crushed to the ground in all aspects by this thing.

The only problem is that the chip area is a bit large and generates a lot of heat. It seems that the cooling fan needs to be used in advance.

Thermal knowledge: Early PCs did not have CPU cooling fans.

What a great harvest!

Gao Zhendong suppressed his excitement and began to clean up the mess. Except for the instruction tapes, none of these things could be left outside.

Everything else was fine, but Gao Zhendong couldn't help shaking his head when he saw the huge storage device made up of a bunch of magnetic core memories.

This damn thing is such a rip-off!
-
The first thing Gao Zhendong did when he got to work was to prepare to post seeds... no, post pictures!
A phone call was made to the computing center, asking them to come and get the drawings of the 2.4k modem. It was a simple thing, with only three things: the circuit schematic, PCB diagram, and BOM list, and they were all stored on a disk, which was gone.

To Gao Zhendong's surprise, after hearing the whole story, Chief Engineer Chi of the Operation Institute smiled bitterly on the phone.

"Chief Engineer Gao, this matter is no longer ours. We are responsible for software development and hardware research and development, but hardware production is the responsibility of other units."

He knew what Gao Zhendong had, and basically he would take the initiative to ask people to get it, as they were all close to production status.

Gao Zhendong was shocked when he heard this: "Ah? When did this happen? Which unit is more suitable to be responsible for this than you?"

Chief Engineer Chi said on the phone: "It will be established soon. In fact, the people are still almost the same as before, but the unit is no longer ours. It's not that we don't want to come to pick it up, but according to the department's arrangement, we will violate discipline if we come to pick it up. So, I will notify the department, and they will arrange the connection. By the way, Mr. Gao, the software programming and hardware research and development are still ours, don't forget."

This matter is over, but the big head is still there.

Gao Zhendong was confused. What the hell was going on?
"Don't bother me. I'm too lazy to receive anyone. Besides, if you send someone else, the formalities will be a big problem. It's better not to bother two people. You should come and get it. For production, it's mainly you who provide technical guidance. If the department has any objections, just say it's my request."
