    Mac SE/30 logic board problem

    If you read the link, that region only accounted for 1% of the world's tantalum output. That being said, Kemet makes an entire line of conflict-free tantalum caps.

    Need assistance with interpretation of Macsbugs error

    No, it just means that you don't have a ROM symbol table file installed and configured for MacsBug. You don't need it to use MacsBug, it just assigns names to various locations within the system ROM. It's handy for debugging sometimes, but MacsBug doesn't need it. It might also be that the OS is so frozen up that it can't service the request from MacsBug to load the symbol table properly.

    Mac SE/30 logic board problem

    Perhaps he does, I didn't see it mentioned though. More telling is that judging from what he himself has said about that chip, you'd think that if he powered the board up, he'd at least have been able to tell OP that there were further issues. Which all comes back to square one: if OP had to tell uniserver what was wrong with it, then it must imply that either the board was damaged in transit (I find that unlikely, unless the solder job was of poor quality, but that's neither here nor there) or that it was never tested after repair. Considering that he probably has an SE/30 around to test it in, why wouldn't he have done that? Why would he let the opportunity to possibly make more money doing further diagnosis slide? It's not exactly something good to think about. In short, I think uniserver's monopoly status remained for so long because for the most part, anyone who would have been capable of accurately criticizing his repair jobs wouldn't be doing business with him anyway, as they would have done a DIY recap job.

    Sure enough, you're right! I had never seen that before so I wrongly assumed that Apple only used those silvery SMD fuses.

    It's ironic given that uniserver has an entire thread on UE8 issues on ThinkClassic.

    Ceramic caps are not polarized (current only flows in one direction), whereas electrolytics are. Audio circuits depend on the behavior differences between the types to work properly. That's why you have distorted sounding audio. Edit: besides, if you want to have electrolytics that don't leak, tantalum is an option. This was what Apple used on the 950, which is why they're relatively immune to cap issues. Ceramic is not an acceptable substitute for a polarized application, tantalum is.

    Recapping requires some initial investment in soldering tools and supplies, but it balances out in the long run because once you've made that investment, each board you recap costs you under $10 in materials to do, give or take. Plus you can do it in under an hour and not have to send it off. Edit: And by the long run, I mean after only about 2 or 3 boards compared to Charles' prices.

    Hooboy, where to begin. I took a look at the photos carefully: all of the SMD electrolytics have been replaced with non-polarized ceramic caps. I also see that your SCSI and ADB fuses have been replaced with what look like MOVs (WTF?) instead of the proper fuse type. You need to demand that he put the proper components on the board, or pay someone more reputable to do it.

    Wasn't there an entire thread on that where at least five people said they were either currently doing recaps or were willing to do them right after uniserver got banned?

    I don't know why he did that hackjob replacing those axial caps with radials that look like... that contraption. It's not only aesthetically ugly, it's poor workmanship. Why couldn't he just get the right kind or at least make the hack look nicer?

    Your first problem was that you sent it to Charles.
  12. This was a commonly-published trick to extend battery life on PowerBooks found in several books, particularly MacWorld Mac Secrets. By running from a RAM disk, you never had to use your PowerBook's HD, thus extending your battery life.

  14. Off hand, I think SwitchRes does that.
