  1. Oh I see. I dont want to remove anything I dont absolutely have to. I understand this stuff at a novice level and have dont simple solder jobs (poorly I might add) and I really dont want to damage this thing any further. Today I spent time reading and digesting Trag's post on the SMC capacitors he has for sale and soldering tips. I feel like I can safely remove the burnt capacitor. I may be confident enough to replace it as well but I'm going to have to practice on some old worthless boards laying around. I dont know if I should go that route or find someone to do the job properly and pay them.
  2. Very helpful. Thanks a bunch. I will get to work on it this weekend hopefully.
  3. Hi, thanks for the info and help. Would you instruct me (or point me to instructions) on how to check that regulator? From what I read in a thread by BadGoldEagle, it could be the PSU going bad putting out bad power. In which case I wouldn't want to reconnect it and attempt any thing more until I know the PSU is good. There is a pricey one on eBay but then again I dont know if its good either. They seem to be known to fail. Also I'm quite excited about this computer. During my middle school years I had a 040 and I literally never had one problem with the hardware so I dont have much experience with them. I may have a lot of questions. I have several beige PPC machines working at home but no 0x0's and I want to get this baby all fixed up right. I know a lot about standard PC parts as Ive done IT for 20 years but that doesn't do me much good here. In your other reply you said you take them apart and clean them. My board looks pretty good but there some spider webs at the bottom and a little bit of dust. What is the best way to clean this board? Battery is removed and there is that one burnt component. Just a dusting with compressed air and soft cloth or alcohol/water? etc. I have several power Macs at home that are in real need of cleaning and the info would be helpful. Thanks.
  4. Well... I dont know if that would have helped in this case, I definitely didn't detect and moisture and its been in climate control for 72 hours but yes you're right... I was more worried about the PSU being bad and putting out voltages that could damage the board, that may be what happened. I disassembled and found the culprit... Please tell me this can be fixed. I think I can solider a new one in place if I can get the right part. I just hope nothing else was damaged in this process.

    BGE's take on the Quadra 900/950 ATX PSU Mod

    Hi guys. I dont mean to hijack this thread but in doing some preliminary searches I came across this incredibly fascinating thread and wondered if you guys might tell me what happened when I powered on the 950 I just acquired. Link to my post, I hope I did not damage the board. Im not sure if I have the electrical expertise to do the mod as you suggest. There is a PSU on eBay (for an arm and leg) that I may buy if it will get me running. Thanks for any advice!
  6. Hi Guys, Im new to the forum (and restoring vintage tech) but pretty active in r/vinatgeapple. Last week a gentleman who cleans out warehouses in search of old tech posted on r/vintageapple and had a 950 in his haul. (see album here https://imgur.com/a/ypS1VTJ). I made him an offer and he shipped it to me straight up... The outside is nasty but the board is quite clean. So I attempted an initial power up of the 950 just now. I connected power and pushed the power key on the keyboard (hard drive unplugged form data but hard drive power was connected. The fans raved and the system chimed. Immediately followed by some pops and flashes emitted from the circled area. I immediately pulled the power and since then the office has smelled of electrical fire (I believe its ozone, not sure if that the right term though). Whats my next move? Could it just have been dust burning off? Caps busting? Remove the PSU and open it? Any help is appreciated. Im very excited to get this baby going. Thanks!
