    How To Test Macintosh IIsi Logic Board

    Yeah I did a close inspection of it the other day and from what I can see everything looks good. No corrosion, no gunk, its pretty clean. I did lift a pad on one of the caps but that is besides the point as it still wasn't working even before I did that. I did repair it though. From what I can...

    How To Test Macintosh IIsi Logic Board

    Alright thanks! Guess I'm just gonna have to bit the bullet and get a new one. Is it an extremely bad idea to take out the new caps I put in the broken one and use them to recap a new one?

    How To Test Macintosh IIsi Logic Board

    That's what I think but is there anyway I can test with a multimeter to see if the Logic Board got fried? Or is that pretty much out of the realm of possibility?

    Macintosh IIsi Power Supply Repair

    I've cleaned it as best as I can. I made sure to scrub the areas under the caps while I was recapping. In order to do a better job I would need to either ultrasonic clean it (which I don't have) or desolder everything and scrub it. I understand that some fluid would cause damage in the long run...

    Macintosh IIsi Power Supply Repair

    Trying to make a long story short I recapped a IIsi power supply, it worked for about a week then started blowing fuses all the sudden when I plugged it in. Replaced D101, still blowing, replaced TH101 with a 0A one, fuse still blew, replaced it with a 2A one and this time nothing blows but...

    IIsi PSU Daughter Card Lifted Pad

    Lifted this pad on the IIsi trying to reseat a capacitor. My wick got stuck and then when trying to pull it off without burning myself it lifted the whole capacitor along with this pad with it. How do I do a bridge wire? It looks like there is literally nowhere to put it without connecting it to...
