Siheyuan starts from the stationmaster

Our company specially designed a software spree for school customers. Each computer uses ten teaching software including the RoyalTek-Dos operating system. The package authorization fee is only 200 US dollars, and 22 computers are 4400 US dollars!

Therefore, the total investment in building a computer classroom in your school is 46668 US dollars.As for manual services such as installation and commissioning, our company will provide all free of charge, and also provide a one-year after-sales warranty service! "

After listening to the girl's words, White nodded, thinking that it would only cost more than 4 U.S. dollars to build such a computer classroom, and the school's budget of [-] U.S. dollars was enough to build two more computer classrooms.

White smiled and said: "Okay, thank you! I need to discuss with others before making a decision."

Seeing that the business was not negotiated on the spot, the girl couldn't help feeling a little regretful, and wanted to find another opportunity to try her best, and said politely: "Sir, is it convenient to leave a business card? After you think about it for a few days, I will contact you again!"

White took out his business card and said with a gentlemanly smile: "This is my business card. I will make a decision soon in a few days. If my school chooses to buy your company's products, I will come back later. You, thank you for your service."

After he finished speaking, he stood up and gave up his seat to other people who were waiting for consultation. Unlike the principals of various schools who were generally concerned about the construction of such a computer classroom, how much money would be needed, the computer teachers who came to the exhibition expressed their appreciation for the computers and equipment on the booth. Networked teaching system is more interesting.

The networked teaching system of Aikang Company is the prototype of the later LAN. In 1979, Metcalfe, who invented Ethernet, left Xerox's Palo Alto laboratory and established the later famous communication network company - 3Com. 3Com has already developed an Ethernet adapter, also known as a network card.

3Com mainly designed network adapters for large and small central hosts such as IBM and Dec, and they did not focus on microcomputers at all.Because in the eyes of most people, microcomputers in this era are just personal toys for computer enthusiasts, and there is no need for networking at all.

This state will not change until a large number of PC-compatible computers appear in the mid-80s and gradually replace minicomputers in the business office field.

Bai Zirui realized the opportunity by taking advantage of his rebirth. Although the performance of a microcomputer called a personal computer is far behind that of a small computer, it is cheaper than a small computer. The total investment of the computer classroom LAN is only 5 US dollars.

For a dec company's VAX system that also has more than 20 users, a small computer plus terminal equipment costs at least 20 US dollars, and the small computer system also needs to build a special computer room, and the system administrator needs to undergo technical training.Not to mention the huge post-maintenance costs, the initial investment of [-] US dollars alone is beyond the reach of most small and medium-sized enterprises.

Therefore, although the performance of the LAN system developed by Aikon is not necessarily high, it is undoubtedly very attractive to schools and small companies.

Odin pointed to the chassis one size larger than the main chassis of the abc computer under the podium desk, and introduced to the audience around: "This is the server required for networking, and its main task is to manage the network and store shared data , at the same time as a bridge for data exchange between microcomputers.

Its performance is higher than that of ordinary microcomputers. You can understand it as a low-end version of minicomputers. The Internet-connected server of our Aikon Company uses Motorola 68000 processors.

It is not complicated to use. Our company has compiled an operation manual. If you have computer skills, you can get started after reading it!If you really encounter problems that cannot be solved, our after-sales maintenance engineers of Aikon will deal with them within 24 hours. "

All the people present were discussing the networked operating system of Aikang Company enthusiastically. Several people who claimed to be good at technology, after obtaining the consent of Odin, personally operated it on the computer and felt the magic of this networked system. .

Thomas stood silently behind the crowd, observing the excited or excited expressions of the crowd. He had a keen intuition as a reporter. This time, the Aikon company came prepared this time, and it seemed that a new era was about to emerge.

Thomas went back to the consultation area backstage, where there were more people than on the booth.There were long queues at the fifteen consultation windows.Thomas was about to go to one of the consultation offices to inquire, and saw Principal White, Ms. Li Wang and other people from San Marino High School not far away were discussing things together.

When Thomas walked close to them, he heard a teacher say excitedly: "The networked system of Icon is so easy to use, it will make our teaching pressure much easier. I suggest that the number of people in each computer teaching class be The number of students can be increased from 20 to 25, so that more students have the opportunity to take computer courses!"

Computer courses are not compulsory courses stipulated by the school district, but elective courses for students who are interested in computer knowledge.According to the original plan, the two computer teachers will only lead two teaching classes per semester, with [-] students in each teaching class.

That is to say, only 80 students in San Marino High School have the opportunity to take computer courses every semester.But if the teacher is willing to increase the number of students in each class to 25, one hundred students can take computer courses every semester, which is good news for the school.

Principal White glanced at Ms. Li Wang, the chairman of the school board, and saw that she nodded in agreement. He made a decisive decision and said firmly: "That's the decision. The school chooses Akon's network Teaching system! I'm going to sign an agreement with their company, and let their company arrange people to come to the school to install the machine as soon as possible!"

"Computer Enthusiast" magazine published in August: "Half a month ago, the author received an invitation card for a personal computer campus exhibition from Dingtian Company. Dina High School, so the author decided to go and have a look with a relaxed mood!
The abc computer newly launched by Acorn, a subsidiary of Dingtian Company, is not an epoch-making invention. At least in the author's opinion, it is just a copy of the Apple 2 computer.

The technological highlights of this new computer, which Ikon emphasizes strongly, are nothing new in the author's opinion.For example, in the publicity of Aikang Computer, it is believed that the dual CPU design can greatly improve the computing performance of the computer. The z80 processor on the z80 card is actually a second cpu.

Another example is the networking solution designed for school computer teaching by Aikang Computer in the on-site teaching class of the exhibition.It is said that this LAN technology was invented by Aikon, a researcher who was a Ph.D. student at Cambridge University. The founder and inventor officially named it Cambridge Ring.
