Then no one believes it.

　　 Hewlett-Packard produced calculators for 72 years, and it was completely because their boss made a joke with others and made a bet to study it.

　　 is the gambling agreement. It took HP only 3 months in 1972 to produce the first truly meaningful handheld calculator with LCD display.

　　 Then in the remaining 7 months of that year, 100,000 calculators priced at $395 were sold.

　　 And at the beginning of the product design, it was used by professors in the computer department of the university.

　　 is not the 10 numbers most familiar to people in the future, plus four arithmetic keys and equal signs.

　　 There are more than 60 buttons.

　　 But just sold to scientific research institutions, universities, and other researchers, they sold 100,000 units.

　　 It is precisely after making a lot of money on calculators for several years that HP will have enough funds to research computers.

　　 Even if it weren't for the calculator's profits, HP's failures of several products might have already gone bankrupt.

　　 If this is simplified to a regular version that will definitely defeat professional calculators, the ability to sell one million units a year will only be limited by output.

　　 This is more profitable than stealing money, but it must be more profitable than getting a computer first.

　　Because, compared with calculators, computers in this era are only used by companies and various organizations, just like printers.

　　 And the audience of calculators is too wide.

　　 In non-professional fields, the mental arithmetic ability of ordinary people in Europe and the United States is generally not good due to natural reasons of education and language.

　　 Annie went to the best girls' school, and she was in the twelfth grade, but when she asked her 258 times 50, she would catch her blind.

　　 Then he took out the slide rule that was specially used for calculation in this era.

　　 A kind of special slide rule with vernier caliper that all Europeans and Americans would buy as long as they have calculation needs before the advent of calculators.

　　 Since computers are still a niche, and the difficulty of research and development can be calculated annually.

　　 Of course, Li Changheng would choose a calculator that is simple and has a market.

　　 After the establishment of the company, with the income of the calculator, he then studied the computer.

　　 not only has enough money for research, it will not make people feel too obtrusive.

　　 After all, no matter how smart he is, people will have the highest expectations when they look at him.

　　 Someone who had never thought of a university suddenly came up with a computer that was absolutely high-tech in this era.

　　Moreover, it can also combine technology with similar products on the market.

　　 This a little exceeded people's expectations of him, and it seemed too enchanting.

　　Countless examples tell him that people fear people who are too much and too much better than themselves.

　　 Then rumors of demonization will appear.

　　The calculator is much simpler.

　　 Register the patent for the design first, and the rest is to hire university professors, or doctors or graduate students from the Department of Computer Science, to understand the relevant technologies of this era.

　　 You don’t need to do in-depth research by yourself, you just need to know whether the prior technology can be produced.

　　 What is the approximate cost?

　　Of course the importance of confidentiality, without being reminded by others, Li Changheng has always been the first place since he came into this world.

　　 50,000 pounds of sponsorship fees went out, and he obtained the right to use a fully equipped laboratory in the University of London with a monthly rent of 5,000 pounds.

　　 Then the recruitment letter, three times higher than the professor’s monthly salary, was sent from the University of London to the professors and associate professors of the Department of Computer Science.

　　 Someone took the initiative to go to the laboratory to find Li Changheng on the same day.

　　 Two days later, among the 6 professors in the Department of Computer Science, 4 professors, along with their assistants and doctoral students, became his personal teachers.

　　 Someone taught how to use the equipment hand-in-hand, and some people taught theories and practical techniques, and poured them into his mind.

　　 Then Li Changheng, who knew what the product he wanted, began to buy and customize what he needed.

　　 But I didn't expect to learn and learn, and I feel that computers and related knowledge in this era are more like making TVs and refrigerators, only focusing on hardware research.

　　 You don’t need to know how to produce all the parts, you just need to know how to put them together, which is a computer.

　　 If it is equipped with a form software and a printer, it will be an integrated office product of this era.

　　 Since this is the case, just learn more.

　　 The courses are very tight and I listen very carefully. I ask questions from time to time, but I only ask but don’t answer, let alone test papers.

The assistant lecturers and doctoral students who 　　 taught him did not know how much he had learned.

　　 It was not until a month later that he began to ask questions to four professors, and the professors were amazed by his memory and understanding.

　　 I feel that what I have learned is enough to let myself know if someone is fooling him.

　　 In the following days, with the assistance of 3 barristers and 6 paralegals.

　　 Signed a new contract with the University of London, clarifying that any technology he researched in the university laboratory is in his hands.

　　 and a professor who specializes in motherboards and his 4-member team signed a contract for commissioned research.

　　 Lee Chang-hyung who knows what the product he wants and the prospect of future sales.

　　I would rather give tens of thousands of pounds as a commission fee than give the team any equity and any sales share.

　　 Then he appointed Zhang Tianzhi as the security supervisor of the laboratory, and called to Hong Kong and Kowloon to call Tyson Ferranch as a security guard.

　　 Anyone who enters or leaves the laboratory in the future will not only have to change clothes, but also have to be checked.

　　 did not call the death squad to come over, because he did not want the squad to understand and be familiar with his influence and situation in England~lightnovelpub.net~ and he would not bring Zhang Tianzhi and Feranci when he went to the United States.

　　Furthermore, Zhang Tianzhi and Felanqi didn't understand anything related to technology at all, and they were not based in England, so it would be very difficult for them to be bought off.

　　 Another month later, Annie told him again that when Gosford Manor invited him to the appointment for the second time, the design draft of the calculator circuit board had been released.

　　 just wait for the plan to be determined, and apply for a patent as soon as possible.

　　 Then I asked the chip manufacturer to make it and try to see if there is any problem.

　　 So, when the calculator was about to succeed, he didn't want to leave London at this time.

　　 Even if it was a day, even Annie and Andrew begged him.

　　 Fortunately, Annie didn't like her cousin John Gosford, and she hated Countess Silvia.

　　 Li Changheng refused to go to the appointment two times. She was only worried that her mother was upset, but she was not angry at all.

　　 But he didn't expect that, I thought Earl Angosford would die out of contact with his niece, who refused after another.

　　 But two days later, Annie told him that the hunting invitation and the cocktail party had been postponed to September, one month later.

　　 Li Changheng looked at Annie in amazement, and saw that this little Nizi smiled and took out a newspaper.

　　 took a look at the newspaper, and saw the front page with the headline "The Beginning of the True Decline of the Nobility" on it.

　　 "Someone is scolding us, are you still laughing?"
