Chapter 61 Why don't you write one yourself

After the death of LUS's grandfather, VIC-20 became his personal computer. He did a lot of things with this computer. In addition to writing small tool programs such as Morse code converter, he also wrote several small games, including his own original ones and imitating some commercial games.

This computer was used until he was 16 years old.

His second computer is Sinclair_QL, which is still in use. At that time, the PC (personal microcomputer) was not powerful, so he chose this kind of relatively niche computer with 68008 chip as the CPU. This computer was very advanced at that time, with a 32-bit CPU equipped with an operating system called Q-DOS. Its memory has also reached 128K bytes, which is dozens of times more than the 3.5K memory of his original VIC-20.

In order to buy this computer, he spent all his scholarships, but it was still not enough, so he had to borrow another sum of money from his father.

LUS is very satisfied with this computer. It not only has a powerful configuration, but also looks very cool, which is very in line with the aesthetics of LUS. Its whole body and keyboard are black, and the shape is not as round and fat as those popular computers on the market, but angular, and the keyboard is also connected to the whole chassis.

Later, LUS purchased a lot of external devices for this computer, such as the electronic base carrying the EEPROM card and the floppy disk controller.

Because the Sinclair_QL computer is very niche, he can't find the after-sales repair point of the whole manufacturer in Finland. In order to buy these supporting things, he had to find a way to look through many product catalogues and telephone catalogues, and finally found the address and phone number of the manufacturer. It took a lot of hard work. UK mail order to these parts. And in the end, due to the lack of fan clubs that use such computers around him, he eventually had to write his own drivers so that these peripherals could run successfully.

This computer can indeed meet the needs of LUS in the early stage, but recently he has become more and more dissatisfied with this machine.

"Man, do you know that this machine is only equipped with a read-only operating system. You can't make any changes to this operating system. It's too inconvenient." LUS complained on the radio, "And, recently I found that as long as I run a program with multitasking, the machine will crash. This is too bad. You know, in the manufacturer's brochure, it is clearly said that this machine is competent for multitasking... It's abominable! They launched a system with serious bugs to the market, and finally let us users pay the bill. After such a long time, they didn't even consider upgrading the operating system at all. It's too bad!"

Lin Hong, who has been listening to it all the time, responded, "My friend, you are so happy. This is your second computer, and I haven't even seen what the computer looks like until today."

LUS was silent for a while before saying, "I'm very sorry, man, I didn't mean to."

Lin Hong replied, "I just made a kind joke. Dude, since their system is so bad, why don't you try to write an operating system by yourself? Design and write according to your own wishes, and I believe you can succeed.

This time, LUS stopped for a long time without replying.

After a long time, he finally said, "Write your own operating system? Hey! This idea sounds good, but it takes too much work to write an operating system. Can I finish it?

"Everything starts with simplicity. You can make a simple system first, meet your own needs first, and then slowly expand the function. Well, you have to consider this at the beginning of the design. Lin Hong remembered the process of making his own radio station. He believed that everything was figured out, so he put forward his own suggestions according to this idea.

"Man, I have to say that I was convinced by you. You're right. Since Q-DOS can't meet my needs, why don't I write one myself? However, I still feel that my machine is out of date, so I decided to start saving money to prepare for my third computer. Dude, come on, find a way to get a computer, and you will love this magical and charming world. Looking forward to writing your own operating system with you.

After chatting for a while, LUS was so sleepy that he had to go to bed.

After Lin Hong ended the connection, his brain was once again in extreme excitement.

LUS's experience has had a great impact on him. He really envies that LUS has been exposed to computers at such a young age, and has done so many interesting things with computers. He is about to celebrate his thirteenth birthday this year, but he has not even seen the computer so far.

How can I have my own computer?

This question now seems to be very unrealistic for him. He put this idea behind for the time being and thought of his mother.

He looked at the time. It was already after one o'clock in the afternoon, and his stomach began to coo at this time. He hadn't had lunch yet.

Should I go back now?

Mom won't leave again, will she?

Thinking of this, Lin Hong couldn't sit still any longer. He stood up, walked out of the room, locked the door, and immediately ran home.

He is really worried. What should he do if his mother leaves again?

Thinking of this, he ran faster and faster. As a result, when he passed a ward, he accidentally collapsed under his foot, and his whole right leg stepped directly in the paddy field. Not only were his shoes soaked, but his right leg's trousers were also covered with mud.

He couldn't take care of so much and ran back home quickly.

When he came to his compound out of breath, a hanging heart fell again.

He saw his mother busy in the yard with an apron.

There is a round table in the middle of the yard, which is already full of dishes, which is very rich.

Feng Wan put a plate of Lin Hong's favorite braised pork on the table. She was about to ask Lin Changming to find her son, but she looked up and saw him standing at the door.

"Xiaohong, come on, mom made your favorite dish for you." Feng Wan smiled.

Lin Hong walked over slowly.

At this time, Feng Wan saw that half of her son's trouser legs were soaked with mud, and couldn't help asking with concern, "What's wrong with you? Did you wrestle?"

She hurried to Lin Hong: "Is there any injury?"

Lin Hong shook his head.

Feng Wan took her son's hand and came to the inner room. At Lin Hong's prompt, she found the trousers and shoes to change.

Although the economic conditions at home have improved, Lin Hong's clothes are very few. Most of them were bought during the Spring Festival. In the past two years, his health has risen relatively fast and is a little small.

Feng Wan looked at her son's clothes that had been washed a little faded, and secretly wiped her tears.

When she wanted to change her son, Lin Hong stubbornly refused. He hid in the room and changed his trousers by himself, then soaked the dirty trousers and shoes in the bathtub, then poured washing powder, and planned to wash them after lunch.

Feng Wan has been watching her son do his own things, and tears can't help flowing down again.
