Cupertino is one of the core cities of Silicon Valley in the United States, this city is not big, but it is a small livable city in the United States, and Apple has its headquarters here since its founding.

The president of Apple is Steve Jobs, who is only 21 years old this year, and he can be regarded as a teenager, because of Chen Yihua's financial support, Apple's development is very smooth.

In the past, Steve was not as fortunate as he is now when he first founded Apple, in the original history, Jobs sold his Volkswagen car in order to raise funds for the mass production of computers, and at the same time Woz also sold his cherished HP 65 calculator. In this way, they had $1,300 in money from Apple's foundation, and in the early days of its establishment, the business of "Apple" machines was very light.

In this life, because of the support of Chen Yihua, Apple's establishment capital has changed from 1,300 fast US dollars to 100,000 US dollars, and there are sufficient funds to operate, Apple not only has a large assembly plant, its first computer is much better than the previous life, but the appearance is also much more fashionable and beautiful than the applei in the previous life, most computers did not have monitors at that time, but applei used TV as a monitor. Compared to later monitors, although the display function of Applei can only slowly display 60 words per second, it is still better than some other computers on the market, and the host computer ROM includes bootstrap code, which makes it easier to boot. Apple has also designed a cassette interface for loading and storing programs, running at high speeds of 1200 bits per second.

After applei went public, the sales volume was much higher than in the previous life, Chen Yihua's funds solved Apple's big problem, so that the company's manpower is very sufficient, and also let Apple computers have their own sales team, after applei was listed, there were more than 800 applei computers sold through sales, but don't underestimate these more than 800 computers, you must know that this is not the next generation, there are not many people who can use computers, applei is a simple product, it is rare to have so many people to buy it, In the previous life, the applei only sold more than 200 units, and now it is four times more than in the previous life.

In fact, applei did not make much money for Apple, compared to Chen Yihua's investment funds, Apple is still in a state of loss, the retail price of an applei is 1200 US dollars, sold more than 800 units, excluding raw materials and labor costs, the profit of a computer is about 400 or so, that is to say, applei can probably earn more than 300,000 US dollars.

Apple has been established for so long, Chen Yihua not only invested the initial 100,000 yuan, but also needed a lot of funds for computer production and research and development.

With Chen Yihua's financial assistance, Apple's strength is much stronger than in the previous life, although Apple only takes out applei for sale on the market, but Apple has developed appleii a long time ago, and the fertilizer water does not flow into the fields of outsiders, and Chen Yihua's company in Hong Kong uses this product.

Appleii has made some additions and improvements on the basis of AppLei. It first improved the case and keyboard, and the case was designed with a plastic case - the chassis at the time were almost always made of wood or iron - which was beige. The second was the ability to display color graphics - which was difficult to do at the time. Appleii also includes a larger disc, more expandable memory (starting at 4000) and 8 expansion slots. It is an integer basic hardcoded disc for easier programming, and can also use two gamepads and a presentation box.

The biggest difference between appleii and applei is the redesigned TV interface, which integrates the display into the memory, which helps to display not only simple text, but also images, and even color display. The video controller displays 24 lines x 40 columns of capital letters on the screen. It uses NTSC hybrid video output, which is suitable for displaying images on a screen or on a TV with an RF module connected.

Apple has also partnered with Microsoft to build the IntegerBasic programming language into its ROMs. Microsoft's basic language software is simple and easy to learn, which also makes Appleii easier to work.

As for why Apple has not sold Appleii until now, firstly, because the company's internal engineers found that there were many places to improve after developing Appleii, and Apple hoped that this product could be designed more reasonably, and secondly, because of Chen Yihua's financial support, Apple is not short of money now, and Jobs They also felt that the company sold Applei first, which would help the company understand the market and let Applei sell in the market for a period of time. It can be used as a warm-up for the company's sales in advance.

And now there are two big projects going on within Apple, because these two projects also make Apple have limited energy, and it has also given up selling appleii during this time.

Chen Yihua is the big boss of Apple, Jobs and Steve Wozniak do not have much of his shares, the design of the appleii, Chen Yihua did not interfere with the design of the appleii, he knows the current technical content, even if they tell Jobs the design concept of their computer now, the appleii can not become the computer of later generations, and according to Chen Yihua's thinking, the cost of the appleii will definitely be much higher, and people now spend more than 1,000 US dollars to buy a computer is someone who will buy it, But if the computer costs more than three or four thousand dollars, then even if someone can sell it, it will not be widely available.

Chen Yihua did not interfere with Apple's research and development of Appleii, but instructed Jobs to tilt Apple's research direction towards chip processors and storage technology devices, and he hoped that Apple would form a scale in these two technologies, and eventually have a manufacturing plant for these two technologies.

applei now uses the 6502 chip produced by Motorola, don't look at the chip technology is a high-content technology, in fact, the production process is very simple, the United States is a high-tech country after all, the raw material wafer of the chip is not only produced by Motorola, there are many experts in integrated circuits here in Silicon Valley, and there are also a lot of equipment that Apple can buy, there is enough money, there are enough talents, plus equipment, after buying raw materials from other companies, for the research and development of chips, Apple only needs to reprocess the wafer, and it doesn't take long for the company to have its own apple0001 chip.

The composition of the wafer is silicon, and the silicon is refined from quartz sand, and the wafer is purified (99.999%) by silicon elements, and then these pure silicon are made into silicon crystal rods, which become the material for quartz semiconductors for the manufacture of integrated circuits, and the slicing is the wafer required for chip making.

Without its own wafer manufacturing plant, Apple is only processing chips for processing, and the cost price of manufacturing is not as cheap as buying 6502 chips from Motorola, but Chen Yihua's vision is to the future, although Apple's current chips are not completely autonomous, and the cost is expensive, but after all, it is Apple's own thing, and the core power is much stronger in its own hands than in the hands of others.

Chen Yihua knows that the wafer is a material that will be widely used in the future, Apple will establish its own wafer manufacturing plant in the next step, and further realize chip independence, when the time comes, Tianyi does not need to buy goods from other companies, with Apple's support, Tianyi does not have to be afraid of foreign companies blocking themselves in materials, Chen Yihua wants to take these good things in his own hands in the future, with Apple's experience, it is also much easier to introduce these technologies.

Jobs and Steve Wozniak are not only Apple's two decision-makers, but also two technical talents, Warts is good at the overall design of computers and the development of integrated circuits, and Jobs is more interested in computer disk drives, Jobs hopes to design a machine that can be linked to the computer's disk drive on the appleii prototype, so that the computer's memory is larger.

Chen Yihua is very concerned about the progress of Apple, even if the contact with Jobs in Hong Kong has not been broken, although Chen Yihua was not born in the computer major in his previous life, but after all, he has the vision of later generations, and the ideas he put forward have also given Apple a lot of help, so Jobs respects Chen Yihua's ideas very much, and the ideas in computer design will be passed to him from time to time to solicit his opinions.

Hearing that Jobs wanted to engage in an external machine for disk drives, Chen Yihua thought that it was a removable disk.

IBM is now the largest computer production company in the United States, this company first introduced disk drives in its Model 305RAMAC in 1956, in 1956, IBM's IBM 350RAMAC is the prototype of modern hard disks, but at that time this hard disk was about the size of two refrigerators, and its storage capacity was only 5MB.

By 1973, the IBM 3340 came out, and it had the nickname "Winchester", which came from his two 30MB storage units, which were the caliber and reload of the famous "Winchester rifle" at the time. At this point, the basic architecture of the hard disk was established.

Computer floppy disk drives appeared in 1967 when the storage group at IBM's Sanjose Labs was tasked with developing an inexpensive device to store and transmit microcode for mainframe processors and control units. The device had to cost less than $5 so that it could be easily replaced, and it had to be portable, so the development of floppy disks began.

By '76, floppy disk drives and hard disk drives had appeared on computers, and computer storage devices were much more mature than other parts of computers, but these disk drives were placed inside computers, and mobile disks did not appear.
