Continuing my repairathon and in this video I'm going to take care of a heavily damaged 386 mainboard J-Bond A340C-H. Music by Model Povedeniya modelp.bandcamp.com/ Patreon: / necroware
As always amazing work. I wanted to thank you because thanks to your videos I was able to restore my old 386 PC motherboard and show my son the games from our childhood. Thank you very much my friend!
It's always an exciting day when you post a new video. I really freaking appreciate how you don't cut corners and really take care to restore these boards with a proper professional eye. Then in top of that, I get tool care advice, hard earned from experience tips, and even some super relaxing music expertly fading in and out as needed. These videos clearly take a ton of time and work, and it shows. Thank you!
Another amazing video of saving a vintage MB from the crap pile. You sir, must have the patience of a saint to remove all those components and sockets and then repair all those tiny traces. Great Job!
I learn so much by watching you, I've got a couple of quirky boards and I'm going to have a really good look at the traces. Your videos are Gold for me.
Congrats resurrecting this board from certain death, love watching your repair videos, great patience and of course skill, thanks very much, always look forward to the next one. 👍👍
Congratulations on a successful repair with that board! Most would have thrown it straight into the parts bin, but you, fortunately, have the dedication to persevere through the mess the battery made of that board. Thanks for the look at your work.
Just whow!! I don't care much for old hardware, but I admire your work so much! It's already very satisfying to watch - how fulfilling it must be to actually do this yourself!? Thanks for sharing these videos!
holy cow!!! that was A LOT work but you pulled it off!! I don't have the patience for this type of work anymore, so its fun to watch others do it, and do it well! :D
A few years back such extensive battery/capacitor leakage repairs were preserved for rare machines only, like big-box Amigas, 68k Macs and whatnot. Certainly not for your "average" late model 386dx boards. "Just get another one from evilBay/etc." But those times are over. I guess at this point almost everything from that era is worth saving. Edit: Oh, and of course great video, and amazing skills. Loved it. Glad the thing came back to life in the end.
I'm loving this stuff. You and others who do board repairs have inspired me to learn a bit about electronics, so I picked up an AM FM radio kit to learn a bit about components and soldering! Can't wait to get started on it next week!
Fun timing with vwestlife's video recently about turbo buttons, and this is another example of "turbo on" being the normal, fast state of the computer, and not a slowed down state.
Great job! I now also got a huge amount of old hardware, and most of it was flooded. A small part, including, it seems, a bag of old RAM, I threw away stupidly (my relatives convinced me), and now I regret it, but now I am gradually restoring the rest, and your videos are my inspiration. Perhaps when I take up the restoration of solid computers, I will shoot it on video
This is truly an artful demonstration of highly skilled solder work. Absolutely beautiful work. I only hope to be this skilled and be able to make it look this easy one day as well.
Really awesome repair job! Always awesome to see an old 386 board like this come back from the dead. I didn't realize you could use the TL866 for testing ICs like that, very cool! I've only used mine for reading/writing BIOS chips so far.
Im always amazed of the ability you have to repair all of these! Great job dude, keep on doing it like this! Always amazing to see new videos from you!
I nearly fell out of my chair when you resoldered those two ISA slots back into place before testing, you're certainly a lot more confident in your repair work than I would be! Great job on this though, and I love the technique of feeding a fine gauge repair wire directly into the IC's through-hole adjacent to the pin. Many times the vias and through-holes are compromised and this provides a robust and elegant solution for those cases, as long as you have a tiny bit of extra space in the hole.
Great work, especially with ISA slots. I was worried that one last break was going to be under reinstalled ISA slot, but you were lucky. :) Also you could go with stacked sockets to accommodate for sockets for small ICs, but glad that it turned out ok. I have a 386 board myself that is waiting for repair, gonna do it some of these days.
Great repair, you're an insipriation and I love these quiet, relaxed videos. I'm going to have to pursue my need to build an XP "retro" machine of my own before the year is out!
Man, your repair technique with a soldering iron is immaculate! I might suggest, though, that you could use female pin headers to make a pseudo-socket for the keyboard controller, and that would give you room to put sockets for the other chips. Stack pin header strips to gain the clearance needed.
Super nice Videos!!! Mega interessant wie Du bei der Fehlersuche und Reparatur vorgehst. Ich hab mir schon den einen oder anderen Tip von dir zu Herzen genommen. KEEP UP THE GOOD WORK!!!
The pins on that oscillator look "normal" to me. All of the oscillators I have in my collection have pins that look about twice as long as they need to be if placed in a socket. So that's probably just how they come from the factory, and just need to be trimmed down a couple of mm if that's your thing. 🙂
That was a pretty good repair. Well done. I would probably have tested the board before soldering the ISA slots back in though. Anyway, let's hope the board lives a bit longer.
I really regret trashing two 486 boards with corrosion on them... You have shown me how to do the job properly, I always thought they were not possible to save. I saved everything socketed at least.
Very nice video! I learn so much from watching you, and as I've said before the way you repair traces is just a work of art. This particular video will definitely come in handy soon, as I have a 386 board myself that needs new ISA slots. I've been holding off on it, but seeing you do it, it doesn't look too hard honestly, just time-consuming. :) Keep up the wonderful work, I love these videos.
Great! You really have magical skills to make such dead old boards coming back to life! So amazing! Congrats and thanks for this entertaining video! 👍👍
Watching your videos give so much nostalgia when i started with computers like XT and one 286 with JUKO Motherboard 19mhz and 1mb ram, 20mb gb samsung hd
I have an idea for the chips under the keyboard controller. Put the chips under the controller in an IC socket and stack two IC sockets for the controller.
Excelente video, son muy educativos e ilustrativos, solo que mi esposa dice que no debe hacer limpieza sobre la tarjeta madre que ya está limpia. Saludos desde Mérida Yucatán México.
The 386 DX40 was my personal computer of my childhood, while the family 486 was great, the 386 was in my bedroom, and many hours of doom was played on it. :P I even put windows95 on it at one point, and ran mIRC with a dialup internet connection. The conversations in dalnet's or efnet's #teenchat was sometimes so much, the screen would stall and only catch up doing a full repaint. :P good enough! I'd almost like to have a 40mhz 386 in my collection. I wonder if I could find space for one ... hmmm...
After washing circuit boards with soap and water and following rinse down I also use 91% rubbing alcohol, shake/fan motion, and paper towel to absorb any excess then let it sit in a warm area to completely dry. The rubbing alcohol does wonders to remove all water.
