    SE/30 logic board foreign object?

    I cant see anything missing on the FDD and the computer had no HDD when I got it so It must have got jammed in there by sheer chance on a workbench. I have now pulled it out with tweezers.

    SE/30 logic board foreign object?

    After some serious inspection of the back of one of my SE/30 logic boards I found the shown object jammed between two pins of the UK6 Video ROM? Can't be right surely?

    Need help hunting the other end of a trace on a SE/30

    Is there a guide somewhere on how to read and understand Apple schematics between pages? as I have traces to follow too and would like to know how to do this.

    Maybe a bit expensive for a clip-on lens?

    Ethernet card stops SE/30 booting

    Better than that I have a small milling machine with a .005mm DRO scale on the depth and before taking a scalpel to the chip I was tempted to mill away some of the case, so I might do this yet based on the image ChisPVille posted, but even then I think I’ll still have to tease a length of the wire away from the case to give me a chance to solder a wire onto it only.

    SE/30 display crashing to black with a raspberry sound

    I genuinely accept some of that, as I attended a lecture on Graphene presented by Andre Geim at Manchester University, but most faults have outcomes and the solving of them is of course greatly assisted by knowing how something should function according to spec. as also knowing the underlying principles, maths or science of how an individual part works, or a number of parts work together in a system to produce a designed outcome, and in the field of mechanics some old-school carburation faults can be quite tricky too.

    Thanks, I saw a list of caps for the PSU on the forum so I will price them up, but I’m used to fixing cars so I also like to find and know the root of a problem too and whats bugging me is not knowing what’s happening in this case before I proceed - even if I have been barking up the wrong tree for a while

    Thanks, but what do you thinks happening? a part broken winding or something else? and can I fix it.

    Hear the sound in the linked video, this currently produces a freeze https://drive.google.com/file/d/1SibxgDg2GXzSS3FbXpL_kLLB7dQUK-g1/view?usp=sharing Plus a frame of the event from the video!

    I don't know as it was a gift but this must be the cheapest! https://www.ebay.co.uk/sch/i.html?_from=R40&_sacat=0&_nkw=clip+on+lens+for+iphone&_sop=15

    SE/30 display crashing to black with a raspberry sound

    Hi Techknight, ... but the glue on my flyback transformer is still yellow and I think the fault lies elsewhere, so I'm now resolved to some serious checking of the logic board according to schematics as I'm still getting the "bzzz" but now it causes a freeze instead of a black screen and that's progress.

    Ethernet card stops SE/30 booting

    In retrospect I tried the wrong approach in trying to attach a wire to the protruding stub as I was using a soldering iron and the stub kept quenching it's heat, I got it tinned but with persistence I eventually broke the stub off Glueing a wire on the surface of the package so one end touched the stub and then using a minute amount of solder paste and focused heat might have been a better way to go?

    “Bzzzz” It’s back and after yet another inspection of the analogue board I found three more suspect joints

    Alas I can't repair it, but HOW I tried
