Chapter 732 Great Harvest
System certification! Absolutely ahead!
Gao Zhendong felt secretly happy, but then he felt less happy.
What kind of thing 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 has been reduced from 120MB to 64KB."
Gao Zhendong laughed angrily when he saw it. The crushing of future technology, without even considering technical issues, can crush today's computers with just one capacity.
This should be the actual embodiment of the 120MB hard drive in the 700C, which is implemented using magnetic core storage. The biggest problem is that 120MB is too big for today. Gao Zhendong even suspects that if tape storage is not included, the total number of external memories in the country does not have 120MB.
In current domestic computers, if the external memory is not a tape, it is a magnetic core. Generally, it is only a few K, and the top-level ones are dozens of K. A 120MB hard drive is 120,000K. In addition, you will know at a glance that the capacity of a hard drive is probably The total number of magnetic cores in the country is enough.
It seems that the hard drive is still not working, but Gao Zhendong is not in a hurry. He knows where the current problem is. Now that it has been solidified and extracted, he will have enough time to solve this basic technical problem after fixing the CPU, and then raise it again.
Looking at this behemoth, Gao Zhendong shook his head and turned his eyes to another circuit board.
This is a memory stick, the same problem as a hard drive. 16MB of memory is really huge for current computers.
Therefore, the capacity of this memory stick has been compressed to 32k, which is already very large. At this time, the memory of mainstream computers was only a few kB.
This is due to Gao Zhendong’s creation of C6110.
Fortunately, this time the system did not lazy to use C6110 to assemble the memory modules. After all, C6110 is a 10μm process, and the best integrated circuit process in the world is now 3μm!
This is why Gao Zhendong has to conceptually develop the 3μm process despite the possibility that the process is immature.
The system only recognizes whether there is one or not! It’s okay if you don’t recognize it!
So this memory stick is very simple. There are only 8 chips on it, one chip is 4kB, and the total is 32kB.
In Gao Zhendong’s previous life, the first 16Kbit DRAM used 5μm NMOS. However, Gao Zhendong’s 3μm PMOS process is limited by the PMOS principle and the operating frequency cannot be too high, but the capacity is still no problem. The chip provided by the system It is a single chip of 32Kbit, which is 4KByte.
Seeing this, Gao Zhendong finally became happy. If nothing else, just this thing was 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 swamp all current running memories.
Gao Zhendong turned his attention to the display of this device. For no other reason, it was too conspicuous because it was very flat!
But unlike the color TFT display of the 700C, this thing is a large-head display! CRT's.
Based on current display technology, LCD monitors can only achieve monochrome, and even monochrome grayscale cannot be solved. If you want to achieve color effects, you can only use CRT monitors.
It seems that for the system, it recognizes the color display, not the LCD display. After all, function is the most important.
Gao Zhendong shook his head, and when he was about to turn his eyes to something else, he suddenly got excited and turned his head back.
This thing is flat! ! !
Maybe Gao Zhendong in the 21st century didn't have much feelings about the fact that CRT monitors are flat, and almost ignored this thing.
But anyone who has experienced the heyday of large-head monitors knows how much easier it is to sell flat or cylindrical CRTs than spherical screens!
Even though this thing may be expensive and cannot be promoted in the name of a monitor in China, it is very cool to have a direction to use it.
——Change it and sell it as a flat-screen TV!
Why don’t you scorn the whole world?
Hasn’t this become Zhenxing Electric’s flagship product again?
Even if it is produced domestically, the market facing the Economic Assistance Council countries is not large, and the patent is difficult to be protected in the Ocean Convention country-controlled areas. This is determined by innate conditions and there is no solution.
But Chin Hsing Electric is different. Like tape players, walkmans, and LED lights, Chin Hsing Electric has completed patent protection on Hong Kong Island, and then reverse-licensed it to the country for sale to the Economic Assistance Council area, killing two birds with one stone.
Otherwise, the old man has a big layout. It’s amazing that this window is left open!
Gao Zhendong struck each other with 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 above the 700C that is closest to the current technical status. Gao Zhendong read the manual and found that it was boring. There was no essential change. If I had to say, the speed increased from 1200bps to 2400bps, which was considered an improvement.
But Gao Zhendong's vision was too high, and he was a little 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 that he hadn't realized what it was, he suddenly jumped up.
"Damn it! I have all these things, I'm so excited!"
The system is very powerful, and the nickel-metal hydride battery in the 700C is completely removed.
This is very interesting. Although nickel-metal hydride batteries do not exist now, the basic ingredients that make up nickel-metal hydride batteries are available! And there is no difficulty in manufacturing it.
Nickel hydroxide, metal oxides, and electrolytes are all not difficult, so the system actually managed to sort them out. Although its energy density is not high compared with lithium-ion batteries, its energy density is much higher than that of lead-acid batteries.
Although it has the problem of high self-discharge rate, it is still very easy to use in some communication equipment. At least it is easier to use than lead-acid and cadmium-nickel. The most important thing is that this product does not have the stinky problem of cadmium-nickel batteries - memory The effect is, in other words, not that serious.
Don’t underestimate this thing. Early satellites used high-voltage nickel-metal hydride batteries.
Gao Zhendong happily put away the instructions for 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.
NiMH battery.
In the end, he turned his attention to the ultimate goal this time-CPU. Isn't that what he was doing with the 3μm lithography machine?
Gao Zhendong knew that it was impossible for him to make the 80486. Those things were made of at least 1.5μm CMOS technology, but it would be no problem to make a lower version, right? 3μm PMOS is also an integrated circuit, so don’t treat the bean bag as dry food.
Gao Zhendong carefully read the CPU manual on the computer. Well, it’s cool!
What he got in hand is not easy to define. If he had to say it, it was probably a low-process, 32-bit 80386.
The bit width and instruction set roughly implement the 80486 specifications, but some on-chip functions are 80386 functions, and the running speed is almost at the 8086 level.
In short, to put it simply, this is a low-speed version of 32-bit 80386!
If we look at Gao Zhendong's knowledge of his previous life, he is a freak!
But if you put aside the shackles of his previous life and only consider the chip itself, this is a fucking artifact!
The operating frequency of 6.5MHz, 32-bit addressing and 32-bit data width, just these two items, can lift all computers to fight. If we can't beat them, we will compare the size and power consumption.
It can be said that the goal of 10 times that of DJS-59 has been exceeded on this chip.
After all, the DJS-59 is 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 frequency limit of this thing is only so much, but Gao Zhendong doesn't care.
Let him design it himself. He asked himself that it was absolutely impossible to achieve this goal. The system would have to do it himself.
As for this thing, if you say it is twenty years ahead, there is no problem at all. After all, there was only 80286 in 1982. Except for the main frequency and 1.5μm process, this thing was pressed to the ground and rubbed in all directions.
The only problem is that the chip area is a bit large and the heat is serious. It seems that the cooling fan must be used in advance.
Thermal knowledge: Early PCs did not have a CPU cooling fan.
What a great harvest!
Gao Zhendong suppressed his excitement and began to clean up the mess. None of these things, except those instruction tapes, could be left outside.
Everything else was fine. Looking at the giant pile of magnetic core memories in the storage library, Gao Zhendong couldn't help but shake his head.
This damn thing is so fucking cheating!
——
The first thing Gao Zhendong does when he goes to work is to prepare to post seeds... no, post pictures!
A phone call was made to the computing center, asking them to pick up the drawings of the 2.4k modem. This thing is simple. The circuit schematic, PCB diagram, and BOM list are just these three things, and they are all stored on a disk. They are gone.
To Gao Zhendong's surprise, Chief Engineer Chi of the Computing Office smiled bitterly on the phone after hearing what happened.
"General Engineer Gao, this matter no longer belongs to us. Software compilation and hardware research and development belong to us, but other units are responsible for hardware production."
He knew that the things at Gao Zhendong's place, and basically he took the initiative to ask people to pick them up, were close to production status.
Gao Zhendong was shocked when he heard this: "Ah? When did it happen? Which unit is more suitable to be responsible for this than you?"
Chief Engineer Chi said on the phone: "It was established immediately. In fact, the people are still almost the same as before, but the unit is no longer our unit. It's not that we don't want to come to pick it up, but according to the arrangement of the ministry, we will commit a crime if we come to pick it up. Discipline. In this case, I will inform the department and they will arrange the connection. By the way, Mr. Gao, the software development and hardware development are still ours, don’t forget.”
This matter is gone, but the big head is still there.
Gao Zhendong was confused, what the hell is going on?
"Don't bother me, I'm too lazy to receive others. Besides, if you send someone else here, the procedure is a big problem. If you don't bother the two masters, you can come and pick it up. In terms of production, you are mainly responsible for providing technical guidance. If If the ministry has any objections, just say it’s my request.”
