Hey! So i decided to take-a second look at my retro build plans and now i seem to be stuck between sticking with a 486DX-33 / DX2 or moving to a Pentium (around 100mhz at most. Don't want to go too crazy.) Stuck because i love the extra retro-factor of the 486 and compatibility with more speed …

Unfortunately, there also appears to be signs of damage from the original battery leaking. Even though it may not look terrible on the surface, the corrosion will slowly eat away at vias and internal traces. My guess is the exploding cap was a coincidence and the real cause of flakiness is probably …

Wow. That was a solid-state capacitor and I've never seen one pop like that before. Usually it's the larger electrolytic caps that leak. Also, small orange disk caps like that aren't supposed to look like round light-bulbs. If it were ME, I'd get the ENTIRE MB re-capped by a professional. I got an …

There is text on the caps (hidden from view) that'll show the microfarad and voltage rating. x µf and y V (x is µf and y is voltage) µf=microfarad Checking the nextdoor cap on the row, the only writing i can make out is on the back and reads 102z. Although some slightly different shaped caps (on …

I can't see any rating on it. The popped cap has no visible writing on it, the only thing i got is some writing above it on the motherboard that looks to say: C6+. Theirs a bunch of like-type numbers above the other caps Look at the other caps to see what they say. Based on the layout from the …

I might be able to assist on that. Can you check to see what the rating of the tantrum (Tantalum) cap was that exploded like a light bulb? Also, where're you from? I have a desoldering iron (45W), no-clean flux, lead-free solder with rosin core, and a soldering iron (15W). Just have to order a new …

Best case scenario, you just had a capacitor go bad. However, sometimes it will be found that a particular AT supply, even when in new condition wouldn't fire up until it had a fairly decent load across it, sometimes just a board, CPU, RAM wasn't enough to get them going, needed a HDD plugged into …

Are you sure you plugged the AT power connectors correctly? i.e. such that the black wires go together in the middle. That is the #1 reason why there would be fireworks when turning on (assuming the EVGA PSU is outputting correct voltages). Can you post a picture of the component that blew up? Are …

Maybe also have a look at your Power Supply Quiet possibly, it seems the old AT PSU is having issues turning on, and now even when plugged in, it just makes a buzzing noise and no fan spin. I'm guessing it might have taken the FD-drive with it. Tried using a spair evga 500w atx psu with an atx-to- …

Pull everything but the processor. If it doesn't beep when you power the system up, the board may have other issues. Make sure the buzzer/beeper works, too, though. It beeped and after some tinkering i managed to get it to boot? It seems having my Cf-IDE adapter causes lots of strangeness. Swapped …

Hi all! Thank you for reading my thread. Please excuse my begginer-ness, this is my first ever 486 build and i'm sure i'm prone to...error. Finally got to piecing it together today, but i can't seem to get the computer to POST, or, even display anything on the screen for that matter. The motherboard …

I recently got a pretty good deal on a 486-mobo, cpu an ram combo. Came with 4mb of ram (guess it could a been worse) but whats confusing me is its type. Its 32pin, and i only really see (and usually hear about) 30 or 72pin when i do searches for kits online. Is 32pin some un-normal standard? I'm * …
