Chapter 130 "Agree to Publish" × 5 (3k)

Several staff members from the computing center nearby were even more excited. One staff member couldn't help but shout out: "Yes, yes, yes, although this machine is not small, 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 but ask, "Can't you just take the tape?"

When these words were spoken, everyone was stunned, and then burst into laughter.

Director Li turned around and said, "Director Gao, what is the capacity of this tape?"

"The maximum is about two million bytes."

People in the Institute of Computing were obviously not used to such a large capacity. It's just like when you discuss PB (1024TB) level storage with people today, many people cannot react in a short period of time.

After a moment, Chief Engineer Chi opened his eyes wide: "2k? That much?"

Everyone around gasped. What is storage freedom? This is storage freedom.

Gao Zhendong explained: "In fact, the data density of magnetic tapes can be very high, but due to the nature of the recorder and the reliability of the data, the data density of this kind of music tape can only be between a few hundred kilobytes and a few thousand kilobytes."

Gao Zhendong was still influenced by his past life's experiences, and spoke with disdain for this capacity.

But Director Li and Chief Engineer Chi don’t think so.

"It can store hundreds of kilobytes reliably, which is enough. The 103 machine has a word length of 30 bits, and the capacity of the magnetic drum was only 1k in the early stage, and it was increased to 8k in the later stage after the magnetic core was replaced. The maximum capacity is less than 32k bytes. How can we use up hundreds of kilobytes?"

Chief Engineer Chi was so excited that he expressed his "Bill Gate's emotion" in advance.

Gao Zhendong added a shortcoming, which was the only shortcoming: "The reading and writing speed of this machine is very slow, only up to 1 kilobyte per second, and it is sequential reading and writing, only batch reading and writing, and it is okay as an external storage."

Unexpectedly, the people at the Institute of Computing didn't care at all: "It's enough to be able to store a lot of data and carry it with you. What else do you need? Besides, 1 kilobyte per second is very fast. Although it's not as fast as the magnetic core or your transistor memory, it's not worse than the old magnetic drum."

Director Li also laughed and said, "Yes, the earliest 103 used magnetic drums. The speed was amazing. Director Zhendong, maybe you are ahead of the times and have a very high vision, but in our opinion, this thing should be very good."

Chief Engineer Chi's brain turned very quickly: "Thanks to your general computer architecture, we can 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 machines with low requirements, even this thing can be used as main memory."

"Yes, yes, yes. With this, many pre-programmed general programs can be installed in it and carried with you."

"It's not just the program, it's the data as well. Hundreds of kilobytes, how much data can be stored?"

This is true. If you only store text and symbols, 100k bytes can store about 10 words of English and symbols. In the future, the number of Chinese characters will be half of that because the Chinese character encoding starts at 2 bytes.

Just when the people in the computing institute were excited and imagining the future, Gao Zhendong poured cold water on them: "Comrades, let's try this thing first to see if it can be used. If it can't be used, everything will be in vain."

Chief Engineer Chi, however, did not care and was very optimistic: "It doesn't matter if it doesn't work for now. The principle is fine. It can't be used for now, but it can be used after some modification. Right, right, right, let's try it first, let's try it first."

So everyone connected the lines, and a comrade from the Operation Institute took the tape drive read-write driver written on paper by Gao Zhendong and began to manually input and compile it.

Fortunately, it is written in C. If it was assembly, this process would be much longer.

Soon, thanks to the efforts of the comrades in the Computing Institute, the program was compiled.

After the program starts running, enter the read and write test program.

Now the tape drive read-write driver only involves the core such as reading, writing and start-end mark positioning, including verification. Just put an empty verification function there. When calling it, no operation is performed and the verification success mark is directly returned.

Gao Zhendong asked a comrade from the computing institute to input a random program, and then started the write instruction and manually started the recording function of the recorder.

Yes, it was so troublesome to use a tape recorder back then, it was all done manually.

But the people in the computing office thought it was natural. Why bother? You have never been beaten by the main control console and paper tape input machine of M-3.

Gao Zhendong: I really don’t.

The program is not long and is quickly completed as the tape moves forward, with the display indicating that writing is complete.

But it is still unclear whether it was actually written in.

Gao Zhendong operated the recorder's buttons to rewind the tape.

Then the read command is started and the playback function of the recorder is activated.

As the tape rustled, the program that had just been entered popped up on the screen line by line.

The comrade from the Operation Office checked it word by word, and finally said excitedly: "It is exactly the same!"

There was jubilation at the scene. This thing did not improve the performance of the computer, but it provided great convenience for the popularization of computer applications.

Director Li was so excited that he asked Gao Zhendong, "Director Gao, how much is this machine? Is it expensive? Is it easy to buy?"

Gao Zhendong smiled and said, "Oh, this thing was given to me by my future father-in-law. I don't know how much it costs, but since it is positioned as a civilian entertainment consumer product, the price can't be high. I estimate it to be a few hundred yuan? Anyway, this thing should be cheaper than a TV. It should also be easy to buy."

Gao Zhendong really didn't ask Lou's father how much he was going to sell this thing for. He didn't know much about the specific operations of the business and didn't intend to get involved. He left the professional matters to his professional brother-in-law.

After hearing this, Director Li and Chief Engineer Chi thought of Gao Zhendong's "sucker" future father-in-law and couldn't help laughing. Director Gao is really a talent! Knowing that Gao Zhendong never speaks without purpose or makes irresponsible remarks at work, Li and Chi felt relieved.

A few hundred yuan? That's cheap. Even if it's a thousand yuan, I can afford it!

Amidst everyone's excited discussion, Gao Zhendong asked the comrades from the Operation Institute to do the next work. It would be a bit of a waste for him to do it himself, so it was just right to let the comrades from the Operation Institute do it.

Hearing Gao Zhendong's request, Director Li said without hesitation: "Director Gao, no problem, go ahead."

Gao Zhendong went through the details one by one: "First, we need to continue to improve this read-write driver program. We need to add necessary positioning, block query, verification and other functions, and integrate it into the existing cycle duty environment. We need to make it as transparent as possible so that users do not feel the existence of this driver program and can use it naturally. The simpler the better."

The comrades from the Operation Institute wrote down Gao Zhendong's words.

"The second is to modify this recorder and my digital-to-analog converter, and strive to make it so that at least when reading and writing, there is no need for manual operation of the recorder itself."

"As for the issue of imitation, it will be arranged by the institute itself."

Director Li was a little worried: "Director Gao, we only have this one, what if something goes wrong with the transformation?"

Gao Zhendong showed a proud face: "It's okay, I have asked my girlfriend's family to bring some more back."

Fuck, just pretend I didn’t ask. Director Li resisted the urge to curse.

Now that the mobile storage issue was resolved and it was already evening, Gao Zhendong prepared to go home because Beijing Iron and Steel would be coming in soon and there was still a lot of things to do.

Before they parted, Director Li called Gao Zhendong and said, "Director Gao, the application process for publishing the C language abroad has been put in place, so it shouldn't be a big problem."

Gao Zhendong understood. He didn't have too much hope for this matter. The current situation was complicated and any outcome was possible.
-

Somewhere in Beijing, in an institution, several people were discussing an application in front of them.

This application was submitted by Director Li, regarding the publication of C language-related paper materials.

Director Li and Chief Engineer Chi wrote the thesis themselves, and Gao Zhendong just reviewed it. He was not good at this. In his two lifetimes combined, he had only written one undergraduate thesis in this life, and he was struck by lightning in his senior year in his previous life.

Therefore, in this regard, there is no doubt that I was crushed by Director Li and Chief Engineer Chi, not to mention that this is an entire paper in English.

The first author of the paper is Gao Zhendong, Director Li and Chief Engineer Chi are ranked second and third respectively.

As for the standard called "Programming Language C", the author is only Gao Zhendong, but there are many translators.

The entire standard was not translated in its entirety, only the core parts were translated.

The idea of ​​the Institute of Computing is very simple, just occupy the spot, know that this thing exists, and is made by our country.

Five people were discussing whether to allow publication abroad.

“Does this involve secrets?”

"I don't think so. To computers, it's just like our language. Is our Chinese language also kept secret?"

"I don't think so. There is not a word about our latest computers in this document. Comrade Gao Zhendong simply invented a language and is teaching people how to speak."

"I don't think foreign countries block this, so there shouldn't be any problem. Just like Fortran and ALGOL60, the language itself is not a secret, but the content carried by the language is."

"But Comrade Gao Zhendong is really productive. He made both DJS-59 and this C by himself. Since DJS-59 cannot be released, this C can compensate him."

"'C', the 'C' in our name, it's a really good name, let's post it, it's quite meaningful."

"I think it can be published. We should also have our voice heard in science and technology."

"."

After a heated discussion, the team leader finally asked everyone to vote.

He raised his hand first: "I agree."

Second hand: "I agree."

The third one: "I agree."

Fourth: "I agree."

"I agree."
-

On Thursday, Gao Zhendong brought people from the first research laboratory to a side-blown converter workshop of Beijing Steel Plant, preparing to carry out trial production of the materials for which they had requested assistance from the General Manager.

The project is referred to as “NF Material Trial Production Project”.
