Chapter 130 "Agreed to be published" × 5 (3k)
The staff of several computing centers nearby were even more excited. One staff member couldn't help shouting: "Yes, yes, yes, although this machine is big, It’s not too small, but it can still be carried around.”
Hearing this, Director Li and Chief Engineer Chi turned their heads and looked at him like a fool. Chief Engineer Chi couldn’t help it. : "Won't you just take the tape?"
As soon as these words came out, everyone was stunned, and then burst into laughter.
Director Li turned his head: "Director Gao, what is the capacity of this tape?"
"The maximum is about two million bytes."
Obviously the people in the computing institute are not used to such a large capacity, just like today's people if you discuss PB (1024TB) level storage with them, short Many people couldn't react within that time.
After a moment, Mr. Chi opened his eyes wide: "2,000k? So big?"
Everyone around him took a breath, what does storage freedom mean? This is storage freedom.
Gao Zhendong explained: "In fact, the data density of tapes can be very high, but this kind of music tapes can only reach a few hundred kilobytes due to the recorder itself and considering the reliability of the data. Between several thousand k.”
Gao Zhendong was still affected by the experience of his previous life, and he was quite disdainful of this capacity in his words.
But Director Li and Chief Engineer Chi don’t think so.
“It can reliably store hundreds of kilobytes. That’s enough. It’s enough. The word length of the 103 machine is 30 bits. The capacity of the magnetic drum in the early stage was only 1k. Later, when the core was changed, the maximum was 8k, which is the maximum after conversion. It’s less than 32k bytes. How can we use up hundreds of kbytes?”
Chief Engineer Chi expressed his emotion in advance.
Gao Zhendong added another shortcoming, which can be regarded as the only shortcoming: "The reading and writing speed of this machine is very slow, the maximum can only be 1 kilobyte per second, and it is sequential reading and writing. Yes, it can only be read and written in batches, and it is just fine for external storage.”
Unexpectedly, the people in the computing center didn't care at all: "It's enough to be able to store a large amount of data and carry it with you. What else is needed? Besides, 1 kilobyte per second is very fast, although it is not as good as a magnetic core." Your transistor memory is not inferior to the old magnetic drum.”
Director Li also smiled: “Yes, the earliest 103 used magnetic drums. I won’t talk about the speed. Director Zhendong. Maybe you are thinking ahead and have a high vision, but in our opinion, this thing should be very good."
Chief Engineer Chi's mind was spinning very fast: "Thanks to your general computer architecture. Fu, we can completely use magnetic cores or transistor memories as memory. For machines with high requirements, magnetic cores can be used as main memory, and magnetic tapes can be used as external memory. For low-demand machines, even this can be used as main memory. "
"Yes. Yes, with this, many general-purpose programs can be installed in it and carried with you. "
"Not just programs, but also data. How much data can be stored in a few hundred kbytes? .”
This is true. If you only store text and symbols, 100k bytes can store almost 100,000 words of English and symbols. In the future, the number of Chinese characters will be reduced by half, because Chinese character encoding starts from 2 bytes.
Just when the people at the Computing Institute were excited and thinking about the future, Gao Zhendong poured a basin of cold water on him: "Comrades, let's try to see if this thing can work first. If it doesn't work, everything will be in vain. Blind."
Chief Engineer Chi is indifferent and very optimistic: "It doesn't matter if it doesn't work for the time being. Let’s try it first.”
So everyone connected the line, and a comrade from the computing center took the tape drive read-write driver program written by Gao Zhendong on the paper and began to input and compile it manually.
Fortunately, it is written in C. If it were compiled, the process would be much longer.
Not long after, with the efforts of comrades from the Computing Institute, the program was compiled.
After the program runs, enter the reading and writing test program.
The current tape drive read and write driver only involves cores such as reading and writing and beginning and ending mark positioning. Including verification and so on, it just puts an empty verification function there. When calling it, no Perform any operation and directly return a successful verification mark.
He asked the comrades from the computing center to input a random program. Gao Zhendong started the writing command, and then manually started the recording function of the recorder.
Yes, it was so troublesome to use a tape recorder at that time, it was all done manually.
However, people at the computing center take this for granted. Is this still troublesome? Have you ever been beaten up by the M-3's main console and tape input machine?
Gao Zhendong: I really don’t.
The program is not long. As the tape advances, it is quickly completed and the writing is completed.
But it is still unclear whether it was actually included.
Gao Zhendong operated the buttons of the tape recorder and rewind the tape.
Then start the read command and start the playback function of the recorder.
With the "rustling" sound of the tape, the program just entered jumped out on the screen line by line.
The comrades in the computing center checked it word for word, and finally said excitedly: "Every word is correct!"
The scene was full of joy. This thing did not improve the performance of the computer, but It has provided great convenience for the popularization of computer applications.
Director Li was excited and asked Gao Zhendong: "Director Gao, how much does this machine cost? Is it expensive? Is it easy to buy?"
Gao Zhendong smiled and said: "Hey, this thing was given to me by my father-in-law-to-be. I really don't know how much it costs, but since it is positioned as a civilian entertainment consumer product, the price cannot be high. I estimate it is a few hundred yuan? Anyway, this thing It should be cheaper than a TV. It should be easier to buy.”
Gao Zhendong really didn’t ask Lou’s father how much he planned to sell it for. He didn’t know much about the specific operations of the business and was not prepared to get involved. , leave professional matters to your professional uncle.
As soon as these words came out, Director Li and Chief Engineer Chi thought of Gao Zhendong's "big enemy" would-be father-in-law again, and couldn't help laughing. This Director Gao is really a talent! Li and Chi were relieved knowing that Gao Zhendong would never speak out of the blue when it came to work.
A few hundred dollars? It’s cheap, even if it costs thousands, labor and capital can afford it!
In the midst of everyone's excited discussion, Gao Zhendong asked the comrades from the computing institute to do the next work. It would be a waste to do it himself, but it would be just right to leave it to the computing institute.
Hearing Gao Zhendong's request, Director Li said nothing: "Director Gao, no problem, you say it."
Gao Zhendong went through the process one by one: "First, continue To supplement and improve this read-write driver, it is necessary to add necessary positioning, block query, verification and other functions, and integrate it into the existing cycle duty environment. It should be as transparent as possible so that users cannot feel the existence of this driver. It’s natural for them to use it, the simpler, the better.”
The comrades from the computing center wrote down Gao Zhendong’s words.
“The second is to modify this recorder and my digital-to-analog converter, so that at least when reading and writing, there is no need to manually operate the recorder body.”
"As for the issue of imitation, it will be arranged by the institute itself."
Director Li was a little worried: "Director Gao, what should I do if there is a problem with the modification of this one."
Gao Zhendong showed a proud face: "It's okay, I've asked my partner's family to get some more."
Fuck, I pretended I didn't ask, and Director Li resisted the urge to curse.
Now that the mobile storage matter has been resolved, it's evening. Gao Zhendong is preparing to go home. Jingang Steel is about to enter the scene, and there are still many things to do.
Before leaving, Director Li stopped Gao Zhendong: "Director Gao, the application process for foreign publication in C language has been started, there should be no big problem."
Gao Zhendong understood this matter. , he didn’t have too many expectations. The current situation was complicated and any outcome was possible.
——
Somewhere in the capital, in a certain institution, several people were discussing an application in front of them.
This application was submitted by Director Li, for the release of C language related thesis materials.
Director Li and Chief Engineer Chi wrote the paper themselves, and Gao Zhendong only reviewed it. He is not good at tinkering with this. In his two lifetimes combined, he has only written one undergraduate thesis in this life. In his previous life, he was struck by lightning during his senior year.
Therefore, in this regard, there is no doubt that Director Li and Chief Engineer Chi were rubbing it on the ground, not to mention that this is a paper entirely in English.
Gao Zhendong, the first author of the paper, Director Li and Chief Engineer Chi ranked second and third respectively.
As for the standard called "Programming Language C", the author is only Gao Zhendong, and there are a lot of translations.
The entire standard has not been translated in its entirety, only the core part has been translated.
The idea of the computing institute is very simple. Just take advantage of the situation and know that this thing exists and is made by our country.
Five people are discussing whether it should be allowed to be published abroad.
“Does this involve secrets?”
“It shouldn’t count. For computers, it is just like our language. Is our Chinese also confidential?”
"I don't think so. This thing doesn't mention a word about our latest computers. It's just that Comrade Gao Zhendong invented a language and taught people to speak."
"I think foreign countries don't block this, so there should be no problem. Just like Fortran and ALGOL60, the language itself is not the secret, the content carried by the language is."
"But this Comrade Gao Zhendong is really productive. , DJS-59 and this C are all made by him. DJS-59 cannot be sent out, this C can also compensate him."
"'C', the 'C' in our name, The name is really good, let’s post it, it’s quite meaningful.”
“I think it can be published, and we should also have some voice in technology.”
“.”
After everyone's heated discussion, finally, the team leader asked everyone to vote.
He raised his hand first: "I agree."
The second hand: "I agree."
The third hand: "I agree."
Fourth: “I agree.”
"I agree."
——
On Thursday, Gao Zhendong took people from the First Research Office to a side-blown converter workshop in Beijing Iron and Steel Plant to prepare materials for requesting help from the General Secretary trial production work.
The project is referred to as "NF Material Trial Production Project".
