  After his grandfather's death, the VIC-20 became his personal computer. He did many things with this computer, including writing small utility programs such as a Morse code converter and several small games, some of which were original and others that mimicked commercial games.

  He used this computer until he was sixteen years old.

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

  To buy this computer, he spent all his scholarship, but it was still not enough, and had to borrow some money from his father again.

  Lus is still very satisfied with this computer, it not only has a strong configuration, but also looks very cool, which is in line with Lus's aesthetic view. The whole body and keyboard are black, and the shape is not like those popular computers on the market that are round and fat, but instead has clear edges and corners, and the keyboard is connected to the entire case.

  Later, Lus purchased many external devices for this computer, such as a carrying case with EEprom, floppy disk controller.

  Because Sincir_ql computers were very niche, there was no after-sales service point for the entire manufacturer in Finland. In order to purchase these matching items, he had to browse through many product catalogs and phone directories before finally finding the manufacturer's address and phone number. After much effort, he managed to mail-order these parts from the UK. Moreover, due to the lack of user clubs for this type of computer in the surrounding area, he ultimately had to write his own driver programs to enable the peripherals to work successfully.

  This computer was indeed able to meet Lus's needs at first, but recently he has become increasingly dissatisfied with the machine.

  "Pal, you know this machine only comes with a read-only operating system, can't make any changes to it, it's so inconvenient." Lus complained on the radio, "And recently I found out that as long as I run a program with multi-tasking capabilities, this machine will crash. It's terrible! To think that in the manufacturer's promotional brochure, it clearly says that this machine is capable of handling multi-tasking... How despicable! They pushed a system with serious bugs into the market and let us users pay for it, and after all this time has passed, they haven't even considered upgrading the operating system, how awful!"

  "My friend, it's simply too wonderful. This is the second computer and I haven't even seen what a computer looks like until today."

  "After a moment of silence, he said: 'I'm extremely sorry, buddy, I didn't mean to.'"

  Lin Honghui said, "I was just making a kind joke earlier. Buddy, since their system is so bad, why not try writing an operating system yourself? Design and write it according to your own will, I believe you can succeed."

  This time Lus stopped for a long time without responding.

  "After a long while, he finally said: 'Write an operating system myself? Hey! This idea sounds good, but the workload of writing an operating system is too big, can I do it?'"

  "Everything starts from simplicity. You can start with a simple system, first meet your own needs, and then gradually expand the function. Yeah, when you're just starting to design, you have to consider this point." Lin Hong recalled his experience of making a wireless radio. He believed that all things are feasible if thought through, so he proposed his suggestion along this line of thinking.

  "Buddy, I have to say that I'm convinced, you're right. Since Q-DOS can't meet my needs, why don't I just write one myself? However, I still think this machine of mine is outdated, and I've decided to start saving up for my third computer. Buddy, good luck to you too, try to get a computer first, and you'll definitely fall in love with this magical and charming world. Looking forward to writing our own operating system together."

  The two of them chatted for a bit longer, but Lus was so sleepy that he had to go to bed.

  And Lin Hong's brain was once again in a state of extreme excitement after ending the communication.

  Lus's experience had a great impact on him, he sincerely envied Lus for being able to come into contact with computers at such a young age and doing so many interesting things with them. He is about to turn thirteen this year, but has not even seen a computer yet.

  How can I have my own computer?

  This issue now seems very unrealistic to him. He put this idea aside for the time being and thought of his mother again.

  He glanced at the time and it was already past one o'clock in the afternoon. His stomach also started growling around this time, as he hadn't eaten lunch yet.

  Shouldn't I be heading back now?

  Mom won't leave again, will she?

  Thinking of this, Lin Hong could no longer sit still, stood up, walked out of the room, locked the door, and immediately ran home.

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

  As he thought of this, he ran faster and faster. As a result, when passing by a ridge, his foot slipped accidentally, and his entire right leg was directly trampled into the paddy field. Not only were his shoes soaked, but his right pant leg was also covered with mud and water.

  He couldn't care about so much, and quickly ran back home.

  When he finally arrived at his own courtyard, panting and out of breath, the hanging heart finally fell back down.

  He saw his mother tying an apron and busy in the yard.

  In the center of the courtyard was a round table, already filled with dishes, very sumptuous.

  Feng Wan placed a plate of Lin Hong's favorite braised pork on the table, just as she was about to ask Lin Changming to go find their son back, but when she looked up, he was already standing at the door.

  "Xiao Hong, come quickly, Mom has made your favorite dish." A smile appeared on Feng Wan's face.

  Lin Hong walked slowly over.

  At this time, Feng Wan saw that her son's pants legs were all wet with mud and water, and she couldn't help but ask: "What happened? Did you fall?"

  She hastily walked up to Lin Hong's side: "Is there anywhere hurt?"

  Lin Hong shook his head.

  Feng Wan led her son by the hand into the inner room, and under Lin Hong's guidance, found a pair of pants and shoes to change into.

  Although the family's economic situation has improved, Lin Hong's clothes are still scarce, and most of them were bought during previous Chinese New Year celebrations. In the past two years, his body has grown faster, and many of his old clothes have become too small for him.

  Feng Wan looked at her son's clothes that had been washed until they were somewhat faded and secretly wiped away tears.

  When she wanted to change his son's clothes, Lin Hong stubbornly refused. He hid in the room and changed his pants himself, then casually put the dirty pants and shoes soaked in the bathtub, poured detergent on them, planning to clean them after lunch.

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