Something happened today and it was delayed.

～～～～～～～～～

"It's not the same, it's all drawing boxes, it's no different from making that pacman, hehe. Da Li said easily, this seemingly simple interface still took him three days and three nights.

"Okay, okay, count you out, this is just a superficial effort, and it's hard to come. "I have been thinking about it for a long time, and I am ready to write a program that everyone can use, let's discuss it, and use this drop-down menu structure in the operation interface, let's take a look at it together." ”

Da Li hurriedly begged for mercy: "Brother, I don't have time to spend this with you, you let me go, there are many things waiting for me to do." ”

"It's okay, just let you help me, I'll do it myself. ”

"Business reporting program?" Da Li looked at the plan and asked strangely, "What are you doing here?"

"What else can you do if you sell it?" said for a long time, "I pondered that no matter how cheap a microcomputer is, only those companies will be willing to buy it, and family and individual users are a minority after all." What can the company do when they buy a computer, this is a question worth pondering, typing, or reporting? Anyway, it is certainly not used for playing games. ”

"It's all in English, who will use this in China?"

"Who said that it was going to be sold to the domestic ones," Chang Chang said, "For the exporters, Dr. Yu and I have combined to make software and sell it abroad to make money for foreigners." ”

"Huh?" this obviously subverted Da Li's values, "The program can also be sold for money? Just this floppy disk, is someone so stupid? How much are you going to sell?"

"I don't know. This was a long time to come, and he had no idea the price of the thing, "It can probably sell for a few dozen dollars." "I have long estimated the affordability of Americans, and boldly estimated a number.

"Dozens...... Dollars?" Da Li was completely dumbfounded, his eyes widened, as if he saw the dollar floating down from the sky, "How many roast chickens do you have to buy!"

"Virtue!" Cao Changjiu's YY, who was full of desire, was interrupted by Da Li's words, "You don't want to order other high-grade ones?" and roast chicken, I see that you look like roast chicken." ”

"Brother!" Da Li Yan smiled and leaned closer, his face as if a flower had bloomed, "I'll discuss with you and count me in." ”

"Oh?" "Oh?" looked at Da Li for a long time, and said in a weird manner, "That's not good, you're all people with jobs, you're too busy, I can't hinder your future." ”

"There's nothing like that!" Da Li was indignant, "I've been holding my breath for a long time, we used to beg the devil to sell us things, and now I want to let them taste it." Brother, don't say anything else, your business is my business, and I will help with this favor. Even if you make money in the future, you have to remember to share it with your brothers. ”

"No, you can just see. ”

The Apple II was a flawed microcomputer with a maximum memory of 64k and a CPU of the cheapest 6502 at the time, which seemed to be only a few dozen dollars.

The fact that the Apple II could only output text in uppercase characters greatly hindered the commercial use of the machine, and no one wanted to use a machine that could not do word processing, and these areas were dominated by Wang An's typewriters at the time.

AppleII's display system is a TV,Apple's founder integrated the TV circuit with his unique knowledge of electronic engineering,When others are still using ugly displays to display green characters,AppleIIInters can already connect a superfluous TV to display color images。

It was this idea that made the AppleII attract people's attention, and at the exhibition with 15,000 people, the AppleII demonstrated with a large-screen color TV became a topic of discussion.

It seems that this is the point of the Apple machine, but technology has once again dominated the market, and the genius Apple designer Woz has once again shown his talent.

When Boss Wo worked for Hewlett-Packard, he once dismantled an IBM floppy disk drive, peeked into the internal structure, and with his innate intuition for circuits, he developed his own floppy disk machine, and the circuit was simple and the cost was lower.

With the unique ability of the floppy disk machine, the Apple II beat all its competitors of the time, because no competitor could produce anything to store data.

Good performance, simple structure, and a $500 cabbage price made Apple's unique floppy disk machine help the Apple II become the first choice of almost all computer enthusiasts, and the users of the Apple II at that time were mainly programmers.

It is these hardware technology innovations that have given Apple a place in the fierce microcomputer market, but it is far from the point where it is calling for wind and rain.

What really pushed the Apple II to the throne was the first killer software in the history of the program, VisiCalc, the video arithmetic.

The arisum is not a good program, it is full of bugs, it is difficult to use, and it is almost impossible to succeed.

It's just that the times make heroes, and when the computer is just a high-tech toy, suddenly a software that can make modern business office easier, the sensation can be imagined.

VisiCalc plays such a role, and overnight, the Apple II became the darling of all corporate finance people, and it was a pleasure to watch the table data on the screen scroll like a stream.

It is this idea that Cao Changjiu has been working for, software programming is not a problem, there is nothing that cannot be done, only unexpected.

He wasn't sure exactly when VisiCalc was released, but it didn't matter, because in the long run, the software would be better than it, and the ease of use and affinity of the software alone was not on the same level regardless of performance and bugs - no one in this day and age would have considered whether the software was easy for ordinary people to use.

The most important thing is that the average programmer can now make money with software!

This is not a trivial matter, being able to exchange software for Money has always been the patent of large companies, and it is generally sold with large, medium and small machines, and the source program is sent.

In the era of microcomputers, programming languages were compiled into intermediate code so that the source code could not be seen by the end user, which meant that if you wrote a commercially valuable piece of software, you would not have to worry about piracy.

With these motivations, Cao Changchang decided to take it as a starting point. Spend a little effort to make a lot of money, why not, here for a long time is not worried about competition, to engage in hardware to rely on industrial base and capital, to engage in software only need to use the brain.

Cao Changchang programmed and drew frame diagrams on AppleII during the day, and at night he gave the machine to Da Li to continue and sleep by himself.

Under the long-term oppression, Da Li worked as a coolie, took over the long-term stall after work every day, and continued to process it according to the long-term detailed program explanation, and after a few days, he had become a panda eye and yawned.

However, the progress of the program is still quite fast, mainly because the long-term division of labor is efficient, write the main framework of the program during the day, and fill in the blanks by Da Li at night, and continue to do the unfinished part for a long time, and then write the framework after completion, and repeat until it is completed.

Finally completed when Da Li couldn't hold on, Da Li lost ten pounds in a month, and after the program was completed, he didn't even look at it and fell asleep, so that he was embarrassed for a long time.

But the program is very interesting.,Even for a long time, I feel a sense of accomplishment.,Tens of thousands of lines of code to achieve almost impossible tasks.,If it's not that the 64k memory is too small.,I even want to make the software into a graphical interface for a long time.,Just think about it......

Writing a program is relatively simple, but the hard part is troubleshooting. No matter how careful you are with a big piece of software, there will be problems in actual operation, so the later testing work is essential.

It's just that I really don't want to trouble Da Li for a long time, so I'd better pick up this burden myself!

For a long time, he solemnly named this form software VideoForm, inheriting Dr. Yu's deceased computer.

But this program also bears this name.,Long specially added the menu function to the software.,Although it's very obscene to display.,But according to those who have seen it,This thing is very good.,Very powerful......

Cao Changjiu wrote a help manual while testing, modeled on the spirit of Bill's Gate, and also made a special help program, which can run independently, specifically for those ordinary people to practice how to use.

VideoForm is a proprietary program,Running on the operating system that has been ported to AppleII for a long time,Because the memory is too small,Long endure the pain,Didn't use c language to write,But directly with the assembly line by line to knock out,Fortunately, this thing is not big,Otherwise, you have to buy tofu for a long time and hit the wall。

Mosquitoes, see mosquitoes again!

Long-term angry shooting, it's only May, is it possible that mosquitoes are also precocious?

The test is boring, and it's not the first time I've done it for a long time, but I'm a little unaccustomed to it. In order to write help, he wrote a small program for self-entertainment for a long time to do text editing, but it's just English, which doesn't bother him, or his own things are comfortable to use.

It didn't take long to write the program, but the writing help made Chang Chang's head bigger, and by the time Dr. Yu returned to Shanghai, the things were only half done.
