Repairathon 2022: Repairing a heavily damaged 386 mainboard

[@oldhuntersu]

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!

[@jeremiefaucher-goulet3365]

Amazing repair. You are very skilled. Thank you, I really love this series.

[@nm0490]

It took quite some while to repair this board, but you can never rush art. And you sir, you are an Artist.

[@michaelkreitzer1369]

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!

[@yokotapioka]

Opens KZbin and there is new necroware video. This is the start of a great day!

[@imshirmpinghime-sama5990]

GREAT VIDEO. I just rewatch all your old video and boom, new video update. thank you for great content : D

[@esc2dos]

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.

[@MarcoGPUtuber]

Sleep or Repairathon? I choose Repairathon!

[@cherrymountains72]

I came for the 386 repair, stayed for the music. Absolutely period accurate music, it makes me feel very melancholic as a child of the 80s.

[@SergeyVolkov]

Agreed, its so chilling i accidentally fell asleep right in my chair.

[@kasimirdenhertog3516]

@@SergeyVolkov me too! Also I guess my brain was thinking: ‘Desoldering all those ISA pins - I can skip that bit.’

[@TC_here]

That looked like such a difficult repair.. so many tiny wires in a tightly packed space... nice to see

[@SaltyMeatHook]

386 Doom! Love it! Nice work on all those traces. Wow!

[@Dave5281968]

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.

[@TomStorey96]

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. 🙂

[@GamePlayShare]

This channel is like a tutorial for me. Using tips from here made repairing much easier.

[@JVHShack]

You truly are the *Necro*mancer of hard*ware*! Great video as always.

[@cocusar]

soldering a tqfp 386 would be awesome! I have one from a PLC but I don't have a board to solder it on, that's a shame :(

[@SyxxFtH8]

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!

[@--fishiiki-]

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!

[@MadCatSE]

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.

[@gordonfreeman320]

Incredible attention to detail, hours of work for sure. Excellent video!

[@blakecasimir]

Educational, detailed, entertaining. Congrats on another successful repair NW!

[@christopherdecorte1599]

I enjoy watching soldering of the jumper wires. They look like they always were there. Every time I try it's a mess. Awsome work and educational.

[@crapasanya]

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

[@pedrocaixinha8907]

Amazing. Pure craftsmanship :) your videos are authentic gems. All the best.

[@SobieRobie]

Jeweler's work! Great! Another piece of PC history is rescued by you.

[@No1BRC]

Absoluter Hammer, Gratulation!! ☺ Never give up on any hardware. 💪

[@cromulence]

Absolutely amazing restoration.

[@mrfivethumbs]

Your work is incredibly satisfying. Thank you for saving these motherboards.

[@asanjuas]

Only i can say Phew!! What a work !!!

[@fra4455]

Great video

[@bundesautobahn7]

Die Reaktion zwischen Säure und Base, Essig und Nickel-Cadmium-"Saft", wie das blubbert. Da lernt man mehr als im Chemieunterricht. ;)

[@chainq68k]

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.

[@FrekansTV]

Dude you are still amazing and doing awesome works.

[@Pikachu062]

[@lmuacky3793]

wonderfull video, keep up with this videos

[@JosepsGSX]

Really nice job sorting that massive damage. Excellent!

[@mndlessdrwer]

I had this on in the background and the solder vacuum sounded like a rubber chicken being slowly wrung out.

[@Faolmor]

maaap maap map maap maaaaap

[@necro_ware]

LOL!

[@prozacgodretro]

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...

[@Vermilicious]

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.

[@RalonsoF1]

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! 👍👍

[@piterstein9625]

да, респект, восстанавливать материнские платы с такими повреждениями, тот еще, увлекательный квест))))))

[@pc-sound-legacy]

Your skills are amazing👏 It's a pleasure to watch the board getting fixes step by step.

[@K10driver]

As always a very good Video! I think this repair took at lot hours splitted over some days? Your choice of musik was very nice this time. Im very curios for the next one!

[@necro_ware]

Yeah, my brother had to calm down as you probably remember, so he made this recently extra for the channel ;)

[@Zebpro]

Marvelous video, thank you very much for all the details and the clever advices! ;-) Your videos are so nice to watch, keep up the good work!!! :-]

[@daspec]

Incredible amount of work, knowledge and dedication to save those retro computers! I always learn something new from your amazing videos!

[@mikatorkkeli4932]

have a 286 mobo dissassembly going. Keyboard controller has half of its pins gone because of varta :)

[@patricoso2306]

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.

[@Nukle0n]

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.

[@tomasz89g]

Your hard work and persistence paid off. Glad to see this alive again after such heavy damage, great video. I always play the dwarf in Golden Axe too!

[@therealjammit]

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.

[@artursmihelsons415]

Excellent video and great repair, as always! 👍 It's nice to see another dead board back to life..

[@osgrov]

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.

[@necro_ware]

Yeah, it's really just a lot of patience. Wish you good luck if your repair!

[@mach1stang]

Very awesome repair. I really enjoy your videos. I grew up during this PC era so it's neat to see these old machines again.

[@Wolfie123123]

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!

[@vswitchzero]

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.

[@manuelgeisendorf9724]

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!!!

[@svgaming234]

Great video as always! BTW, which Linux distro do you use? It kinda looks like EndavourOS Xfce

[@necro_ware]

Thank you very much! I use archlinux with xfce since 2008.

[@e1woqf]

Watching you repair this board is very relaxing. There wasn't much I'd have done differently. BTW: what flux do you use?

[@necro_ware]

It's Stanol, I got it from a german electronics store Conrad.

[@tony359]

the idea that you might have missed a bad trace under one of the ISA slots put some serious suspence to the video! :) Great job!

[@ochykysh]

wow...great job.

[@rallyscoot]

no solder mask of nail polish replacement?

[@thecriss88]

If you have a time and knowledge Iyou could do a detail explanation of how a 386/486 PC works including chipsets, pots, IRQs, DMA, etc. On a top of that I would be curious to see a reverse engineering of a BIOS firmware. Later on you could try to re-implement such a PC motherboard (perhaps without a CPU) on a FPGA.

[@jonnivanzelatti4073]

18:00 wow Brazil manufactured ic

[@dixonsoftwaresolutions5031]

Not sure if anyone else has mentioned it, but when your desoldering gun makes that noise, it sounds just like that meme of the girl hitting her back on the bed and going "ahhh!"

[@ДмитрийСергеевич-з4л4о]

Во истину, электроника - наука о контактах!

[@theSoundCarddatabase]

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.

[@rarbiart]

those early ami BIOS colors never stop to disgust me... Amazing repair!

[@mattboomerkaustinen4964]

Great work. I have to do similar to a 386 Gateway I have. What thickness wire did you use? Source?

[@necro_ware]

Here I said couple of words about it last time kzbin.info/www/bejne/m3uXdZ-Insx-rqM

[@mattboomerkaustinen4964]

Awesome thanks! I was thinking the same, I’ll just use some wire wrapping wire that I still have for no good reason 😂

[@renatoscutube]

That's a lot of patience...

[@Porygonal64]

Where did you get that AT power cable? I'd like to get one to test a 486 board I have. I think my power supply might be dead.

[@volkryn]

What's the music used in video? It's not Model povedenia from description.

[@necro_ware]

The music was made by Model Povedenia extra for my channel, but unfortunately the artist never got it managed to publish the work. That was the plan however and I'll give a reminder. Sorry to disappoint you.

[@volkryn]

​@@necro_ware Thank you. Artist did really great job and it's pleasure to listen to this while watching video. Great fit!

[@danielyazbek9910]

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

[@ching-chenhuang8119]

Watching you soldering with those super thin wires, I think I'm going blind......😱😱😱 No way I can detect such tiny broken circuits!!

[@atheatos]

ok wow repair. I am not that patient. I always failed with boards damaged this much.

[@altbeetle1998]

MEGA WORK! I have a 386 motherboard with similar problems, but unfortunately I have absolutely no technical knowledge, so I won't even try to fix it, because I don't know if the work will be in vain. although I practice well with a soldering iron, I am afraid that a purely mechanical correction will not be enough

[@djpirtu2]

I've been struggling with my MG-38606 motherboard. Some Varta-stuff on keyboard connector corner but not too bad. Symptoms are that realtime clock stops when powered off and continues where left off when powered on. CMOS settings stays, I'm using external battery. Other thing is that it gets unstable when warmed up, it's got something to do with cache. Any bios settings wont help with that, tried other set cache chips too. If I put a fan to blow to motherboard, it works. Nothing still gets hot without a fan. Now I'm gonna get it fully cleaned from that varta-stuff with vinegar and wash the whole thing and see does it make any difference.

[@hsubdarb]

Don't care for the background music. Really enjoy your videos.

[@richmond411]

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!

[@FlergerBergitydersh]

I don't want to be that guy criticizing the other guy performing amazing electronic wizardry, but seeing you clean components like the keyboard connector and keyboard controllers OVER the main board made me really nervous. Perhaps there was nothing to worry about, as I have no experience, but I was thinking some corrosion could have potentially dropped back on to the mainboard and caused some problems or something. Thank goodness it didn't! (or, again, maybe there was nothing to worry about)

[@drPeidos]

Great repair, love your videos :) Really great repairs of traces with thin wires. I have a question about the ICs with the broken/corroded legs: If you were unable to find a new replacement for those ICs, would it be possible to remove some of the plastic shell and solder new legs? Or all that work would be for nothing because the inside of the ICs probably was also damaged? Thanks.

[@alexk4894]

Wow, very impressive!

[@southernflatland]

Pressure wash and air compressor, call it a day. Well of course replace the CMOS battery, but still my advice stands, and only takes about 20 minutes.

[@osamely_varan]

such a awesome repair!

[@LeeMc007]

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. 👍👍

[@B1G_Dave]

Everybody: Throw it in the scrap Necroware: Hold my lemon juice

[@gomergomez1984]

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.

[@d3adman404]

17:09 hey look, BRAZIL! Jokes aside, what an amazing work you did.

[@pavelmusiyenko]

Finally at list one person using Commander(NC/VC) to navigate in dos not just command line unlike 98% of other retro computer ch and for some reason they think using commander is longer than typing commands all the time .:)

[@50shadesofbeige88]

Man, you're really good with that iron. You're like a surgeon.

[@Nobe_Oddy]

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

[@catriona_drummond]

I am making slow progress in getting better at soldering and I am always torn between: "I want to be capable of doing that" (e.g. taking off an ISA slot) and "oh god I hope I'll never have to do that". Bit of a paradox.

[@horusfalcon]

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.

[@AbdAlgani1999]

really nice thanks

[@raysgarage2351]

Great job ,don't beat yourself up over missing traces I was in ore when you said you could repair it without a microscope. . Top Marks to you Sir . .

[@jasonhaman4670]

A lot of work, but a nice save! On principle, I hate soldered-on CPUs, but since you have one spare and this board has a place for it, I'd love to see a video of you soldering that processor to this board.

[@Guillermo_XT]

My M326 did the same until i inserted at least 4 memory modules instead of 2 (beeping that the graphics card is missing) Very cool repair episode 🙂👍

[@myriadtechrepair1191]

Jealous of the lack of microscopic components. Really cool repair, always impressive.

[@Alex6joker]

Hi! Great job! How long should 10-15% vinegar work on the board?
