I have a very old pc case from 2002, had an intel 478 motherboard that was my first victim of when I was learning eletronics, the layout from that case is very similar to this one, but in a wide mini tower format, it now houses my oldest setup with an asus p5pe-vm, that I plan to try and install 98 one day there
The magic is, that such a project is not made on one evening ;) But also if you into this hobby long enough, you collect some useful parts over the time.
Yes, that's indeed unfortunate. Believe me I invested a huge amount of time trying to rescue it. But I got no stable signals, so CPU couldn't initialize properly. I guess, some traces inside of the PCB (it is a multilayer one) got corroded and shorted. Well, what do we learn again from this lesson? Always remove the battery from the old hardware.... *sigh* Thank you for your feedback, I'm glad you like it :)
14:31: Another way to do it is to flood all pins with solder causing the socket to fall out itself. Then clean with a desoldering tool if necessary. Two soldering irons may need to be used to maintain heat.
Great job with soldering/de soldering and cleaning up the pads. Why not do the bench calculations on the computer? I usually have only excel (early versions) just for that, and partitioning. What about putting heat compound on the CPU? and ... since its a Intel 286, why not try booting Xenix?
It depends, by far not all systems support that. Furthermore, once you are in the game, you often can't use that combination anymore and have to reboot. With a physical switch it works always at anytime.
Yeah, I'm still disappointed by that, but sometimes it is as it is. This mainboard had too much of damage, most of the traces on the surface were eaten away by the battery acid and was obviously corrosion on the traces inside the board as far as I could see. Well, at least the CPU lives on :)
13:13: It's so dangerous drilling like that. If the bracket catches on the drill... Always use a vice secured to your bench. A battery drill and step drill would be a lot more safer too.
I absolutely love this channel where do you find all these projects from even the non working one my local e waste recycling yard wouldn't let me have or buy any old motherboards to try salvage or even pick parts from nor for me to practice my soldering skills etc I love your work you certainly have a gift mate.

9:18 - Hello again. Please can you explain more about this? Why to put ISA sound card into most bottom ISA slot? Is there any article with more depth on net? I cannot find any.
Hi again! The sound card is very sensitive for electromagnetic distortion. If you put it in between of two other cards, you will probably get more noise on the output. Cheaper sound cards tend to be more responsive for noise, then the more expensive ones. Creative Sound Blaster AWE64 and MediaVision Pro AudioSpectrum are most resistant ISA sound cards against noise, so using them, it is not that important, but for the most other cards it is. Furthermore, if you put the sound card into the last slot, you reduce the distance to the case, which is grounded. This can also improve the sound quality.
It's all retro until it comes to the hard drive because most find it easy to CompactFlash and don't think hard drives are worth the trouble. I always found the old whirring & whine of those drives cool, maybe I'm an outlier in that regard.
In other videos I also use hard drives as well. It's just more convenient to use a CF card. And I like the sound of hard drives in the first minutes, after 10 minutes of using them I get headaches. Especially the older ones from the late 80s, early 90s are very loud.
I have a bunch of old ATX cases around and was wondering if it'd be possible to install an AT mainboard into an ATX case. The shipping costs for shipping a case are getting ridiculous where I live.
Yes, it is possible with some modifications. You will need ATX to AT connector adapter, then you have to think about the power switch, since on AT it is a real switch, but in ATX it's just a digital toggle. On some cases it is possible to replace the switch. Alternatively you can just use the mains switch on the PSU. And optionally you can make a I/O shield cover for the back of the case to cover it from dust. I actually wanted to make a video about this topic, just didn't find any time for that, yet.
@@necro_ware I have a suggestion about the power supply switch problem. I was thinking about using the first bit output of a CD4510 BCD Counter IC to switch a transistor that closes the connection between the green wire and ground. Then using the power button to pulse the clock of the CD4510 with some capacitor de-bouncing. Basically I'm going to use a counter IC as a flip flop latch to switch the power signal so I can still use the original button.
Tell me, did you have to revive power supplies from 286 or 386 but in baby AT case? this cases is a crocodile-like desktop case (similar you in this video but you case is a slightly different) with manually flippable top cover with the side mechanical open-buttons. this cases have a AT-PSU in the L-shape form with a large power seesaw-switch on the side i have died one. he is very strange - in the "cold part"(low voltage part) he have only two c945 transistors
I didn't yet, but may be it is not a switching power supply? Does it have a big transformer on the mains? I actually never have seen a non switching AT PSU, but that probably doesn't mean, that there is none. It would get hot like hell and would be highly inefficient, but hey, in the 80s everything was possible...
