    IIgs battery repair

    The entire logic board is out of the case on an anti-static mat...otherwise I'd agree it was possible!

    IIgs battery repair

    ROM 3, actually. The volume is loud on here for sure. Maybe if I turned it down the sound would be more normal. But...how does one turn down the volume on a IIgs??? I also found that L17 and some resistors still had nasty battery crud, so I desoldered those and cleaned them up, but no better. I...

    IIgs battery repair

    So, more about this: maybe it is a cap or bad connection somewhere else. I noticed that when the 800k drive is working, if I put my ear right up to the speaker, I can hear the head motor's movements. That sounds to me like some sort of electrical interference as was noted. The question...

    Introducing (and interest check) AirTalk: Wireless plug-and-play LocalTalk dongles

    Just an addendum with what cheesestraws said: You can use this with an ethernet network via a localtalk to ethernet adapter. For example, I have an AirTalk connected to my iPrint LocalTalk to Ethernet adapter, and the devices I have on my ethernet network are all accessible by the AirTalk...

    IIgs battery repair

    Wouldn't know what frequency it is at...anything is indeed possible, though I don't know why pressing one solitary sound capacitor would cause it to be worse when moving the others does nothing. There could be crud somewhere from the battery explosion causing the issue...who knows.

    IIgs battery repair

    Ok so the good news is: pulled all the caps, checked them all, all check good. Redid the soldering, made sure to not use too much this time. Sound is loud now! The issue that I have now is that there is a low-level hum, not really perceptible unless close to the speaker, but comes through quite...

    IIgs battery repair

    Yep, for sure, it is the J1 jack. I also used headphones via the headphone port. Same "pop" when turned on, and then that is it. I suppose one of the caps could be a dud...I guess I could out them one by one and use my ESR meter. I looked under the microscope; no bridges, no cracks, no...

    get ADB performa keyboard power button to turn on G4 quick silver...

    Is that why? For twenty years, I have wondered why Apple did away with the one most convenient feature they ever had.

    IIgs battery repair

    A test speaker (from an SE), but it is virtually identical and worked prior to the recapping.

    IIgs battery repair

    Thanks for the PSU info...I suspect a different revision or something. So, not all went as planned. Recap proceeded nicely on the board without issue. However, now I have no sound. I get an initial pop from the speaker, but that is it. So far as I can tell, everything is in order. Cap specs are...

    Won a Performa 5210CD, importing it. What should I look out for?

    We all go through the learning process. When I was your age (a good 20+ years ago), I learned the hard way how not to work on my SE/30 by busting the glass nipple on the back of the CRT. I was lucky that they were cheap as dirt back then. Don't worry, just remember for the next time.

    IIgs battery repair

    Well, very good news: with the blown cap on the logic board replaced, and the two corroded 1 µf caps changed in the PSU, I get clean power within spec, and the B&W startup screen for the IIgs out of the composite video port. Good power on chime with a test speaker as well. So, I guess that is...

    IIgs battery repair

    Caps came, getting started on the recap. Question: can anyone check out their PSU? It looks like I have a component cut out of mine! This has never been modified, nor did I see any components rattling around inside. Check out the photo attached, right in the middle. Are people missing the same...
