Hello my patrons! I'm trying to get caught up after being away in vacation so here's the main channel video that'll come out this weekend. I'm actually always amazed how far I can get behind even though this is my full-time job now. 

Anyway, on the bench we have a broken 486 motherboard that was donated by viewer Matt back in SMMC episode 65. (Linked in the description.) The motherboard had suffered massive damage from a leaking NiCD battery -- so I set out to see if I could get it working.

There is actually something somewhat relaxing about doing this kind of repair. If you have some non working boards, why not give it a try to see if you can revive things?

In other news, welcome to all my new patrons. While editing this up I was shocked at the "New Patrons" section at the start of the video. Normally it's just 1 column on the first text slide, but this time it was four screenfull of names! WOW! I'm still absolutely blown away at the outpouring of support. 

Thank you everyone for all the support!!

Something mysterious happened while repairing this VARTA ravaged 486 motherboard #repair

If you are into retro computer from the late 80s and into the 90s, you are probably fully aware of how destructive the NiCD "VARTA" batteries are to these systems when they leak ... and this 486 motherboard had one such battery leak and cause some severe damage to the motherboard. So, let's try to get this motherboard working again using nothing but inexpensive tools! -- Links SMMC 0065 where this motherboard was first featured: https://youtu.be/cUkJFL4EY00?t=352 Second channel video where I first took a look at this monitor: https://www.youtube.com/watch?v=O4eidkDuegQ Adrian's Digital Basement Merch store: https://my-store-c82bd2-2.creator-spring.com/ Adrian's Digital Basement ][ (Second Channel) https://www.youtube.com/channel/UCbtwi4wK1YXd9AyV_4UcE6g Support the channel on Patreon: https://www.patreon.com/adriansdigitalbasement -- Tools Deoxit D5: https://amzn.to/2VvOKy1 http://store.caig.com/s.nl/it.A/id.1602/.f O-Ring Pick Set: (I use these to lift chips off boards) https://amzn.to/3a9x54J Elenco Electronics LP-560 Logic Probe: https://amzn.to/2VrT5lW Hakko FR301 Desoldering Iron: https://amzn.to/2ye6xC0 Rigol DS1054Z Four Channel Oscilloscope: https://www.rigolna.com/products/digital-oscilloscopes/1000z/ Head Worn Magnifying Goggles / Dual Lens Flip-In Head Magnifier: https://amzn.to/3adRbuy TL866II Plus Chip Tester and EPROM programmer: (The MiniPro) https://amzn.to/2wG4tlP https://www.aliexpress.com/item/33000308958.html TS100 Soldering Iron: https://amzn.to/2K36dJ5 https://www.ebay.com/itm/TS100-65W-MINI-Digital-OLED-Programmable-Soldering-Iron-Anti-static-Structure/113382669853 EEVBlog 121GW Multimeter: https://www.eevblog.com/product/121gw/ DSLogic Basic Logic Analyzer: https://amzn.to/2RDSDQw https://www.ebay.com/itm/USB-Logic-DSLogic-Basic-Analyzer-16Ch-100MHz-4Ch-400MHz-Xilinx-Spartan-6-FPGA/202543965672 Magnetic Screw Holder: https://amzn.to/3b8LOhG https://www.harborfreight.com/4-inch-magnetic-parts-tray-90566.html Universal ZIP sockets: (clones, used on my ZIF-64 test machine) https://www.ebay.com/itm/14-16-18-20-24-28-32-40-pin-IC-Test-Universal-ZIF-Socket-Fs/303206721971 RetroTink 2X Upconverter: (to hook up something like a C64 to HDMI) http://www.retrotink.com/ Plato (Clone) Side Cutters: (order five) https://www.ebay.com/itm/1-2-5-10PCS-Micro-Scissor-125mm-PLATO-170-Electronics-Cutter-Side-Cutting-Pliers/163458746184 Heat Sinks: https://www.aliexpress.com/item/32537183709.html Little squeezy bottles: (available elsewhere too) https://amzn.to/3b8LOOI --- Links My GitHub repository: https://github.com/misterblack1?tab=repositories Commodore Computer Club / Vancouver, WA – Portland, OR – PDX Commodore Users Group https://www.commodorecomputerclub.com/ --- Instructional videos My video on damage-free chip removal: https://www.youtube.com/watch?v=XQVjwPsVFd8 --- Music Intro music and other tracks by: Nathan Divino @itsnathandivino

The link appears to be broken. I get the error; “This Video is Private”

That's normal. It will become public again at the scheduled release time.

I have recently re-discovered something I used to know back in the early '90s, I reckon it must have been. I bet we have all attempted to clean a battery compartment from the mess of some leaky batteries, which has been sitting in there for way too long, and have realized just how stubbornly nasty it can be to remove. Well, just ordinary kitchen vinegar clears it right up like a breeze, no scraping, scratching, sanding or filing needed. I then use IPA to get rid of the vinegar/residue cocktail afterwards. By now you'll be thinking "But standard AA or AAA batteries are not the same as those VARTA batteries we find on old motherboards, does it work with their leaky messes as well?" - and yes, it does. Not that long ago I cleaned a hardened puddle of VARTA-pee off an Amiga 500 memory expansion using vinegar and a humble cotton bud, which such ease, I almost couldn't believe it. You obviously still have to repair any eaten traces, but at least you don't have to worry about damaging it even more, by accidentally scraping too hard.
