It turns out that this machine has no external memory, only a basic photoelectric input machine (for reading perforated paper tape), a teletypewriter, and the memory is two large cabinets.

There is a panel on the main unit, a row of buttons, and this is the start input key.

After the main engine is powered on, it cannot self-guide, and someone must use the keys on the panel to input a series of machine code instructions to activate the photoelectric input machine and read into the paper tape containing the boot program data to complete the start of the machine.

After this series of actions, Cao Changjiu finally revived the computer, but he was sweating profusely.

In any case, it is easy to start it, although the programming of the punch machine is not very smooth, after all, it is not possible to program some points. Cao Changjiu began a hard journey of programming while groping.

I don't know how long it took - anyway, Cao Changjiu just felt that he had just figured out a little bit - the machine didn't respond.

I was stunned for a long time, I was at a loss, and suddenly I was angry, and I smashed my fist on the table, and my hand hurt, but I remembered for no reason that when I first came into contact with the window system, I opened a window but it wouldn't close.

At this time, someone at the door asked, "Is anyone inside?"

He replied angrily for a long time: "Who?"

A young man walked in, dressed in the most ordinary military uniform of this era, and all washed white. A small flat head, revealing a spirit. It's just that the prescription of the glasses is a little deep, like the bottom of a beer bottle.

This guy came up to look at it for a long time, and found that there was a child of Cao Changchang here, hesitated for a moment, and asked, "Is your surname Cao?"

Cao Changchang rolled his eyes: "That's right, what's wrong? Didn't I just crash the machine? I must have taken care of him." ”

The man was inexplicable: "What is the crash? You are Comrade Cao Changjiu, the king arranged for me to assist you, if there is anything you don't understand, you can ask me." My name is Lu Ping, and I am from the second research laboratory. ”

When Cao Changjiu heard that he was not here to trouble him, he immediately breathed a sigh of relief, and immediately took Lu Ping's hand and said: "What a comrade, if there is any difficulty, it will come immediately! You can see why this old antique died like this, and I haven't touched it much before I can touch it." ”

Lu Ping held his glasses and looked at them, sat down and said, "You have started it, how long have you been driving?"

Chang said: "I don't know, maybe a few hours, anyway, I'll come as soon as I get to work." ”

"That's right. ”

"What do you mean. ”

"This machine is an imitation of the nova small machine, domestic goods, basically stable operation time does not exceed four hours. ”

“......”

"I think we can go to dinner, the body is the capital of the revolution, you will have a lot of time to spend with this machine in the future, let's go." ”

Lu Ping was very unhappy with the leader's arrangement, and the dignified assistant researcher was actually sent to take the child.

The task given by the king is to take care of everything for Cao Changchang and answer his questions.

God knows how the water enters the leader's head, Lu Ping is incomprehensible about this task, and when he inquired, he found out that this young man named Cao Changjiu was actually arranged from above.

Even the blind man knew Lu Ping's dissatisfaction, and Wang Suo also comforted him and said: "Don't worry, it is estimated that it will only take a few days, and the child will definitely not be able to stand the boredom here. ”

With the words of the king, Lu Ping reluctantly came to serve this little prince.

The meal is very simple, but it is pickled steamed buns. But the long-term mouth is not idle, and he keeps asking questions. The questions asked were also strange, which made Lu Ping almost unable to parry.

Although Lu Ping hated this messenger, he couldn't help Cao Changjiu's big brother, but he couldn't say everything. The long-term inquisitive attitude also changed Lu Ping's impression of him.

What's more important is the collision of knowledge shown by the two in the question and answer, so that the two have a common language. Needless to say, although Cao Changchang is full of new architecture, it is completely incompatible with this era, but his profound hardware and software skills are consistent. Every sentence surprised Lu Ping, and it was difficult to describe the feeling that it seemed that the person sitting opposite was not a novice, but a long-tested senior engineer.

Lu Ping shook his head, tried hard to expel the illusion, and took a sip of vegetable soup with a "quack", "Impossible thing, high-level languages can't write operating systems, we've tried." In the past, we felt that the portability of the assembly writing operating system was too poor and it was difficult to migrate it from one machine to another, so we tried to write it in a high-level language, but failed. ”

Who said that high-level languages can't write operating systems, he thought for a long time, but he didn't distinguish but changed the topic: "Since it is difficult to port operating systems, why should we only focus on developing a series of computers, just like IBM360, the new hardware system is compatible with old machines, wouldn't it be the best." In this way, whether it is the operating system or application software, it can be reused, and the improvement from generation to generation will save how much labor it will have. ”

Lu Ping smiled bitterly: "How easy is it to say! Although everyone knows that this is the best way, the actual distribution of interests is unavoidable. Do you dare to say that the computer you make is the best? Impossible, and now the general situation is compatible, almost all domestic models are imitated, and now the main owners are playing in the United States, who do you say we imitate? It's dangerous to follow anyone without distinguishing the winner or loser, so the above moves are undecided, so they simply build together. ”

He was puzzled for a long time: "It's nothing, as long as there is a plan above, you can still avoid risks to the greatest extent." ”

Lu Ping shook his head: "Little brother, you are still young and don't understand the Tao here." The task of copying several series of computers from abroad is divided into different departments, who want to give up. Not to mention anything else, just look at the small computer, the country is divided into two factions, and the quarrel is a mess. As for other large-scale computer projects, they are being launched one after another, and they are blooming everywhere. ”

Cao Changjiu said: "It's so complicated, it's better to avoid it, I don't have high requirements, I just want to have a computer to use, hehe." ”

Lu Ping also smiled: "That's it, we just do things, and we don't touch the ones who don't have them." By the way, why are you holding on to that broken machine, wouldn't it be better to go to the machine room?"

Cao Changjiu made a helpless expression: "It's not what Wang asked, he asked me to engage in a multi-channel time-sharing system for keyboard input, display and output." I thought that none of this was a trivial task, and I didn't want to crowd the machine room with a bunch of people. So I had to tinker with that antique. ”

Lu Ping said: "You are really serious, I thought you were talking about playing, and you really want to practice your feelings, can you do it alone?"

Chang Chang said: "At first, I was sure, but then I felt a little difficult to look at the machine. It's not that it's difficult to electrically, but that the old man can't stand it when he loses his temper. ”

Lu Ping said: "That's nothing, let's talk about the fate today, I'll help you." I'm familiar with that machine, I'll handle it for you. There is another sentence that Lu Ping didn't say, that is, he can be relieved sooner if he finishes it earlier.
