  1. That's a good idea. And practice organizing all the screws and bits. I feel the same way; my Cinema Display is still usable and it makes me feel like putting off the teardown until it isn't. I have a ThinkPad with a display upgrade. It made a huge difference but I wasn't the one creating the custom driver. Since all of our LCDs with CCFLs will eventually need it, I'm going to make it a summer priority to do a monitor and a PowerBook LCD.
  2. Thank you, Chopsticks. Yikes, I didn't realize that all the layers have to be separated. Are the layers designed to be removed? Or are they adhered to each other? @beachycoveThe technical sources are the Apple Service Source manuals. The 23" manual is very light on details while the 22" is better. The "impossible" comment came from the MacRumors forum.
  3. I have found sources for ccfl bulbs for both the 22" and 23" Apple ADC monitors but limited instructions on how to do it. The Service Guide for the 22" makes it seems relatively easy but the guide for the 23" has no information. It even goes so far as to state that there are "no offered" part numbers for the bulbs. A random comment I found elsewhere made it sound like a very difficult process. Has anyone replaced them before? I use one almost daily with my contemporary Mac, but I have noticed it dim quite a bit recently. It would be great to have this "youngtimer" class
  4. Thanks, Franklinstein. I did notice that one of the board contacts was slightly bent backward. The dust seemed minimal compared to some machines that I've received.
  5. @LaPorta: Thank you! I had a feeling that there was something peculiar with the magnet but I wasn't sure what could have gone wrong. I have yet to remove the expansion bay drive itself but I am having a problem with a Sony drive as well (not recognizing an inserted disk unless held at an extreme angle.) I vividly recall having a terrible time with the floppy in a 190 as a kid. I'll be curious to tear one down.
  6. Peripherals seems like the most logical place to post this as it spans a few different machines, yet its the internal floppy drive. Problem: a floppy initialized on my 3400c will work with my 8600 tower but then my 1400c will say it can't be read. This happens frequently among the same machines with different disks. And likewise, if the 1400c formats a floppy, the 8600 can't read it. All the machines are running 7.6.1 Any thoughts? Are some drives more forgiving than others for small errors before proclaiming the disk unfit?
  7. Is there a noticeable improvement in boot speed?
  8. Testing out the drive sounds like a good place to start. I'm tempted to make another attempt at finessing mine to boot. OR, here's a prototype Kanga...and the plastics come pre-broken! Proto Kanga
  9. Performa 550 (with 575 board) - All of the sudden, the fan is intermittent. I noticed that it wasn't spinning, tapped the vicinity, and it spun up. It's quiet and when pushed, spins easily. The fan is NMB 3110NL-04W-B20. It's also very clean. Do these have a tendency to fail? Or is it more likely that it's not making constant contact with the power pins? Car light bulbs sometimes need dielectric grease. Would a dab here help? Apple's housing is quite nice; metal frame with rubber dampeners. Although they didn't put provisions for four screws, only two. Also,
  10. That's not odd at all; I prefer it, too. I like the sound but also the "wholeness" of the set up. I've been happy with the SCSI2SD in my PowerBook 550 as those drives are so terribly overpriced now. My original 8600 has the factory drive and it's such a lovely thing to hear. The rescue 8600 arrived without a hard drive or any of the sleds. SCSI2SD was/is a good solution to that, except for this issue. I might just try to find a compatible drive or use the pin converter avenue.
  11. I suppose that's a possibility. So far, I haven't had that issue with any flash media...yet. There's always a first and thanks to irony, it would happen to the card that I bought to prevent that exact scenario. I'll try booting without extensions and then with an older SCSI2SD. Out of curiosity, which General Settings are considered to be correct for PPC Macs? SCSI2 enabled?
  12. I had a similar thought, although I don't know why that would happen. If there was any data issue, I'm inclined to think it is the device and not the card. I bought that card specifically for its industrial grade tolerances. As for temperature, the machine is in the office with others (which have remained fine.) I have a v5.1 SCSI2SD that I could try out. I really want to pin this on the v6 because that's an easy swap out.
  13. Thank you, maceffects. Let's assume its software: what could have changed since last boot to now? It makes me think that the SCSI2SD is corrupting something critical. Its curious. I have a twin 8600 with the same specs save for the original SCSI drive, and it's a-ok. I wonder if the v6 boards are the problem. My older boards have been fine (v5.1).
  14. This machine has been a labor of love. It's a rescued 8600 that I had up and running over the summer with a V6 revF scsi2sd, a 4GB Panasonic SLC card, and a new PRAM battery. It was great- no issues. Glorious 7.6.1 I haven't used it in a few months (left plugged in). Now when it boots it will either not boot (screen is still in standby), boot to desktop and freeze after a few moments, or boot to desktop and open a blank error box (black & white rectangle) and be unresponsive even to the soft reboot. Sometimes if it does respond to the soft keyboard reboot, it won't chime and wi
  15. Yikes, I'm sorry to hear that. Its very disheartening when with good care, they just fall apart on their own. I've essentially given up on my 8500 because so many plastic retainers have broken. Same with a 1400c. It's become a desktop because the hinge destroyed the plastic retainer. ThinkPad are certainly robust- made to be worked on. It seems like the only problem with the older ones is the rubber becoming sticky.
