China DOS Union

I've been playing with DOS for about 20 years. I should have known about DOS from the end of 1985 or the beginning of 1986. At that time, DOS was the best operating system for personal computers.
Now I'm still doing things under DOS, mainly on 86-architecture machines, based on DJGPP + ALLEGRO. I also use TURBO C for some simple tasks. I rarely use assembly language now, only occasionally when I have to.
The advantage of DOS is that it can operate hardware without any scruples and is extremely fast. So my programs basically run on the motherboards I made specifically. For example, the newly developed motherboard for a project uses an AMD gx3 chipset, the bridge uses CS5536, is equipped with an ALC202 AC97 sound card, an bt878a image capture chip, and connects an AIT2138 image decoding chip and a DS3231 high-accuracy clock chip via I2C on CS5536. When DOS is started, it's all directly programming the chips, which is cool to run!
The trouble with DOS is its non-reentrancy, which makes it necessary to be very careful when building multitasking, not being able to do as one pleases. But there's no need to modify DOS for this because DOS 6.22 nowadays is really very stable. If you change it, who knows what might happen. When I was young, I once completely changed DOS in a project, from the keyboard, display to disk operations. As a result, none of the debugging tools could support it, and that project really wore me out.
I don't know how many people are really developing under DOS now. A foreign project a couple of years ago first used WINCE. The foreigner said it was unstable and not reliable after using it. Then I redid it with DOS, and the foreigner kept saying it was good. Originally, it's just to start when you want to and shut down when you want to. Using a 200 CPU, the real-time performance of image capture is extremely good. What else is there to say.

You're really amazing...

The means are really smart, it's always what I've thought. LZ, please give more guidance in the future!

A real expert, admiration, admiration.

Operating systems are still better if they are simple and stable!
The self-written GUI running on DOS is still pretty good. (Also supports Linux, uC/OS-II)

AMD Geode GX3 + CS5536 is a pretty good platform. I have this and it runs WIN XP quite well! And of course, it runs DOS very smoothly!!

I have my own port of the GX2 + CS5535 platform, and it can also run XP...

It's a pity that AMD has discontinued GX1 and GX2. Also, considering the European lead-free requirements, I had no choice but to start making this GX3 board. Originally, the same functional system was always running on a GX1 board using GX1-200, which was sufficient. Using GX3 has undoubtedly increased a lot of cost. Moreover, since it's a self-made motherboard, it generally takes half a year just for various tests and board modifications. What a hassle!

Uncle, you're really amazing! You were playing DOS before I was even born. It's not too much to call you uncle, right?

Of course, it's not excessive. But now young people are no longer enthusiastic about DOS. It seems that DOS is a very simple and easy thing. In fact, programming under WINDOWS is really not interesting. Whether you can do a good job in programming under WINDOWS depends more on how much you know about WINDOWS. Everything is done well by WINDOWS, and you just need to learn to pile things up. Of course, that's also a skill. I don't know how many programmers have been harmed by WINDOWS.

I once had a client who was doing IVR. A long time ago (probably around 1995 or 1996), we had a cooperation. At that time, it was to connect a DIAGLOGIC E1 card to the domestic telephone switching network. Since the China No. 1 signaling was different from the European No. 2 signaling at that time, it was very difficult to connect foreign things. A gentleman from the DIAGLOG office couldn't handle it at all. Helplessly, he found me. It took us 2 weeks of spare time to get it done. The source code at that time was sold for 20,000 yuan. It is said that they resold it for 50,000 yuan. Last year, he found me because their IVR system was a product bought from others, which was made under WINDOWS. It often had inexplicable problems under heavy call volume. Since the bottom layer was all WINDOWS, the manufacturer said they couldn't solve the problem. He asked us to start from the bottom layer. It didn't matter under what system it was done. Anyway, after doing this, if there were any problems in the future, no matter what, he could figure out a way to solve them by himself. I did it for him. It seemed to take 2-3 months. Unfortunately, there were no problems.

The characteristic of WINDOWS is that you must have someone watching it, otherwise the consequences are unpredictable.

No matter what it is, as long as it can effectively solve the problem, right, uncle?

It seems that everyone here is at the BT level!!!

Don't everyone play games developed based on OpenGl???

The building owner is really an amazing person. Back then, I didn't even know there was such a thing as a computer. Hehe. Now the meals I eat mainly rely on this thing called DOS.

There are still people making a living with DOS? Can the friend upstairs introduce it? What kind of profession is it?

Still, the younger brother is amazing. I've also played with computers for many years, starting from Apple II, and I'm getting more and more outdated.
