"Hey, Brother Shen, business is booming! The things I ordered before have arrived, so I'm in a hurry to use them!" Li Xuan approached a shop called Shen Ji Electronic Store on Yaliao Street.

This is a small shop specializing in all kinds of electronic components and electronic instruments, and the owner is a man in his early thirties with an unsmiling Chinese face, named Liu Heshen.

"Well, it's Ah Xuan!" Liu Heshen nodded at him, "When the thing arrives, I'll get it for you!"

Liu Heshen bent down and took out a plastic bag from a storage compartment under the counter: "No, this is the Z80 processor you ordered, and there are exactly ten pieces in a box." Everything else is what you want to be instrumental, the list is here, you can check it yourself!"

Li Xuan took the list of directories handed over by Brother Shen and compared them one by one. These are all tools for programming chips, testers, editors, programming docks, connectors, adapters, and so on.

These things are hard to find, and Li Xuan didn't find any places to sell these electronic instruments when he walked around Hong Kong and Kowloon. Later, I really had no choice, so I had to come to Liu Heshen for help, and the other party agreed to help him buy it from abroad after reading his catalog list.

Li Xuan met Brother Shen when he was upgrading and modifying the Apple2 in the company before. His original computer was the standard configuration of Apple's Apple 2 original market, with a measly 4KB of memory, while the standard configuration of later laptop memory has reached 4G. The difference between the two is a million times. You read that right, not a hundredfold, a millionfold.

Fortunately, Apple has reserved upgrade space for customers, and Li Xuan spent money to increase the memory to 32kb just after his salary in order to make his machine run faster. It was from Liu Heshen that he found the accessories at that time. At that time, he also bought a second-hand Z80 conversion card for the computer under the recommendation of Liu Heshen.

Anyone who has ever used an Apple computer knows that Apple's operating system is always different, with iOS against Android and OSX against Windows in later generations. This tradition has been around since Apple's first commercial computer, the Apple 2. It was not compatible with the CP/M operating system, which at the time accounted for almost 90% of the market.

At that time, most of the software on the market was developed for the CP/M system, and Apple's computer could not run the CP/M system, but it sold very well. Software vendors are naturally reluctant to give up this part of the market, so they began to think about how to move CP/M-based software to Apple 2 to run.

So someone designed a softcard Appleii software conversion card, that is, the Z80 card. The card has a Z80 processor and is able to take over Appleii's bus control, memory address transformation, and interface allocation, so that the CP/M operating system can be run smoothly on Apple2 computers.

The person who designed this Z80 card is certainly no stranger to everyone, his name is Paul Allen, the owner of the NBA Portland Trail Blazers, and a super-rich man with assets of more than $20 billion. It was he and Bill Gates who founded Microsoft that deeply influenced an era. Sometimes you don't think that the world is so small, it turns out that Apple and Microsoft have had something to do with it so early, maybe this is the so-called fate.

Back to the topic, Li Xuan's boss Huo Junming called back before, and the negotiations between him and Epson went very smoothly. There was an unexpected situation that Epson's technicians appreciated the Hanka drawings designed by Li Xuan and intended to buy them from Li Xuan and produce them themselves.

Huo Junming completely agrees with this, all he cares about is the right to sell agents. Since the Japanese side is willing to directly produce printers with Chinese Hanka for the Hong Kong and Taiwan markets, this is the best result for him. This saves him a series of additional costs such as finding someone to produce the Hanka himself, and then loading it into the printer.

In this regard, Li Xuan also said that it didn't matter, who he sold to was not selling, anyway, he was not ready to rip off. It was not difficult for Epson to redevelop a suitable Chinese Hanka on its own. Li Xuan's design just saved some time and cost for the other party.

Huo Junming said that Epson would send a technician to talk to Li Xuan about related matters, and the other party hoped to see Hanka in kind at that time. It just so happened that Li Xuan had approved a check for 5,000 yuan for R&D funds before his boss went to Japan. A PCB (printed circuit board) factory in Kwun Tong Industrial Zone, Kowloon, which he contacted, has also completed several sample circuit boards that he had requested for trial production.

Li Xuan's next job is to solder the Z80 chip to the circuit board, and then burn the number of Chinese characters into the chip, and then it can be installed on the printer for testing.

"Well, everything is right, thank you, Brother Shen!" Li Xuan checked it, and everything was right.

"I will charge you a total of 2,000 yuan after removing the odds, thank you for your patronage!" When collecting the money, Brother Shen's expressionless face finally squeezed out a little smile.

Li Xuan didn't bargain very happily took out his wallet, took out twenty hundred-yuan bills and handed them to the other party, and then asked him to issue a receipt, which was to report to the boss.

Apliu Street is a small street in Sham Shui Po, Hong Kong, which was originally famous for selling second-hand goods, and has gradually become a distribution center for electronic parts in Hong Kong since 70 years. There are many shops selling second-hand electrical appliances and used products on the street. It is bustling here every day, with many Southeast Asian merchants coming to buy goods, as well as many tourists and citizens who come to Taobao.

Li Xuan walked through the flow of people, looking at the various slightly messy storefront signs and promotional billboards on both sides of the street. He suddenly thought of buying a cassette recorder for his little sister Li Ying, she said last time that she wanted to buy and listen to English tapes, but her frugal mother refused without hesitation.

"Boss, do you have a cassette recorder?" Li Xuan approached a video store.

"Yes, why not! What type do you want! I have just recently bought a batch of Japanese Sanyo brand dual-card and dual-seat recorders, with good sound quality, many desks, and beautiful and magnificent at home!" The boss pointed to the most conspicuous position in the window, a black recorder and dual-purpose recorder enthusiastically introduced.

"Sorry, I didn't make it clear. I didn't want this big tape recorder, but a single-cassette tape player that I bought for my sister to learn English and listen to songs. Li Xuan waved his hand.

"You're such a good boss, that's what you're talking about, it's all over this row. There are American-made, Japanese-made, and locally-made factories, you can choose yourself!"

"Which brand sells better, and the quality is more reliable!"

"Then this one, it's a brand of Sanyo of Japan, the quality is very good, as long as you don't break it on purpose, you can't use it to come back to me for a year!" The boss saw that Li Xuan really wanted to buy it, and immediately became enthusiastic.

After some bargaining, Li Xuan spent 200 Hong Kong dollars to buy this Sanyo recorder. Men buy things neatly, and when they choose, they pay the bill, and if a girl follows them, they will inevitably have to visit a few more shops and shop around.

Li Xuan was about to leave, but he inadvertently looked up and found a beautiful figure in front of a stall not far to the left, with long fluffy wavy hair and a white dress. But a man in a denim jacket next to her deliberately approached slowly, and a hand quietly reached for the small satchel that the woman was carrying on her shoulder.
