  1. I've never worked on an '040 in particular, but I seriously bent numerous pins removing an AMD Phenom in another old computer I was working on. I was able to straighten all the pins acceptably by placing a credit card with its edge along the row gaps next to the bent pins and gently rocking it side to side to push the pin vertical. I would do this on both sides of the bent pins, and I would do it in the X-direction, then switch to the Y-direction, then back to X, until the pins were all straight. The result wasn't perfect, but after processing, the pins were all standing straight enough that t
  2. Would you please explain how it interacted with the toolbox? I downloaded the User's Guide and Reference (for different versions, alas), but they just had cursory information about using "Declare" to make a particular Toolbox call invokable. They didn't say anything about where to find the name of the particular library that the call was associated with, or how you use calls that you have to pass, say, a Pascal-formatted string or a pointer to. Is this just not possible?
  3. Disappointing to hear that; I was hoping that would be the solution to both of our problems. I am also planning on cleaning under and replacing the op-amp chip as well, in case the signal from the sound chip is fine and there is actually a problem between audio output pin 10 of the sound chip and the speaker.
  4. I don't have real insight into your problem, but I did just test the '030 in my working IIci, and it gets quite hot (I let the computer sit with no drives installed for a couple of minutes, and the CPU was hot enough that it became painful to keep my finger on it for more than 4-5 seconds). It is curious that /BR is active low, but attached to a pull-down resistor. In my limited understanding, I thought these things were generally pulled high somewhere, and everything connected to it was either floating or low (when a request was desired). When both the CPU and UH2 are removed, wha
  5. Did cleaning and re-soldering the sound ship fix the problem? I had the essentially the same experience with my LC II: sound but lots of weird noise before motherboard wash and recap; very faint sound after, but an otherwise functional computer) and I would love to know if this fixed it for you.
  6. Thank you both. Bolle, that is interesting that you have had that same problem multiple times; obviously a common problem and yet I don't think there was any info on the internet yet regarding it. I was also just reading a thread about the Mac II where a number of people mentioned having problems with one particular trace. It sounds like machines of this vintage have so many very specific "hotspot" problems that it would be good to get this information into a troubleshooting wiki of some sort (or maybe into the model-specific pages on the 68kmla wiki).
  7. I'm a long-time lurker, and all of your posts have helped me greatly. As a first post, I wanted to share my resolution to what appears to be a common problem, as both the resolution and my interim workaround are different from what I'd seen in other posts. My IIci suffered from a seemingly common problem: it would not stay on. I would press the power button on the back, it would begin to boot for a split-second, emit part of the happy Mac bong, and then die. I have seen several recommended steps to resolve this problem in various posts: 1) replace the SMD capacitors and clean the b
