After Lus's grandfather died, the Vic-20 became his personal computer, and he used it for many things, in addition to writing gadgets such as Morse code converters, he also wrote several mini-games, some of which were original and some that imitated some commercial games.

This computer was used until he was sixteen years old.

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

He spent all his scholarship to buy the computer, but it was still not enough and he had to borrow another sum of money from his father.

Lus is still very satisfied with this computer, it is not only powerful, but also looks very cool, which is very in line with the aesthetics of Lus. Its entire body and keyboard are black, and the shape is not as round and chubby as those popular computers on the market, but it is angular, and the keyboard is also connected to the entire chassis.

Later, LUS purchased a lot of external equipment for this computer, such as an electronic base with an EEPROM card, and a floppy disk controller.

Since sinclair_ql computers were very niche, he couldn't find the entire manufacturer's after-sales repair point in Finland, so he had to find a way to look through many product catalogs and phone catalogs in order to buy these supporting things, and finally found the manufacturer's address and phone number, and it took a lot of trouble to get these parts from the UK mail order. And in the end, due to the lack of hobbyist clubs around him who use such computers, he ended up having to write his own drivers to make the peripherals work successfully.

The computer did meet Lus's needs in the early days, but lately he has become increasingly dissatisfied with the machine.

"Man, you know what, this machine only comes with a read-only operating system, and you can't make any changes to this operating system, it's so inconvenient." Lus complained on the radio, "Also, I've recently discovered that as soon as I run a program with multitasking capabilities, the machine will crash. That's too bad, you know, in the manufacturer's brochure, it clearly says that this machine is capable of multitasking...... It's so damning! They put a system with serious bugs on the market, and ended up making us users pay for it, and after so much time, we didn't even think about upgrading the operating system, which is terrible! ”

Lin Hong, who had been listening to it pleasantly, responded: "My friend, you are so happy, this is your second computer, and I have never even seen what a computer looks like to this day." ”

Lus was silent for a moment before he said, "I'm sorry, man, I didn't mean to. ”

Lin Hong replied: "I just made a good-natured joke just now. Man, since their system is so bad, why don't you try to write an operating system yourself? Design and write as you wish, and I'm sure you'll succeed. ”

This time Lus paused for a long time and did not reply.

After a long time, he finally said, "Write your own operating system? Hey! The idea sounds good, but it's too much work to write an operating system, can I do it? ”

"Everything starts simple. You can start with a simple system that meets your needs and then slowly expand the functionality, well, you have to think about that when you first start designing. Lin Hong remembered the process of making his own radio station. Believing that everything was figured out, he made his own proposal along these lines.

"Dude, I have to say I was convinced by you, you're right, since Q-Dos doesn't meet my needs, why don't I write one myself? Still, I felt that my machine was outdated, so I decided to start saving up for my third computer. Come on, man, find a way to get a computer, and you're going to love this magical and fascinating world. Looking forward to writing your own operating system with you. ”

The two talked for a while, and Lus was so sleepy that he had to go to bed.

And after Lin Hong ended the communication, his brain was once again in extreme excitement.

Lus's experience had a big impact on him, he was really envious that Lus was able to touch computers at such a young age, and did so many interesting things with computers, and he was about to celebrate his thirteenth birthday this year, but he still hadn't even looked at a computer.

How do you get your own computer?

The question seemed unrealistic to him now, and he put the thought behind him for a moment and thought of his mother again.

He looked at the time, it was already past one o'clock in the afternoon, and his stomach began to rumble at this time, and he had not eaten lunch yet.

Isn't it time for me to go back now?

Mom won't leave again, will she?

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

He was really worried, what would he do if his mother left again?

Thinking of this, he ran faster and faster, but when he passed a ridge, he accidentally collapsed under his feet, and his entire right leg stepped directly into the paddy field, not only his shoes were soaked, but his right leg pants were also covered with muddy water.

He didn't care so much and quickly ran back home.

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 on.

In the center of the courtyard there was a round table, which was already full of dishes, and it was very hearty.

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

"Xiaohong, come on, Mom made you your favorite dish." Feng Wan had a smile on her face.

Lin Hong walked over slowly.

At this time, Feng Wan saw that half of her son's trouser legs were soaked with muddy water, and couldn't help but ask with concern, "What's wrong with you?" Wrestling? ”

She hurriedly walked to Lin Hong's side: "Did you hurt anything?" ”

Lin Hong shook his head.

Feng Wan took her son's hand and came to the back room, and under Lin Hong's prompting, she found the pants and shoes to change in.

Although the family's economic conditions have improved now, Lin Hong's clothes are very few, most of them were bought during the New Year's festival in the past.

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

When she wanted to replace her son, Lin Hong stubbornly refused. He hid in his room and changed his pants, then soaked his soiled pants and shoes in the bathtub, poured laundry detergent, and planned to wash them after lunch.

Feng Wan kept watching her son doing his own thing, and tears couldn't help but flow down again.
