  1. Me too. As long as the ID and termination power were set appropriately, the drive I tested mounted CDs in Mac OS 7.6.1, 8.1, and 8.6 on a variety of Macs without modifying the Apple drivers or installing third party ones. It worked on 7.5.5 using the Toast 4 driver and in 7.1 using the CD Sunrise driver. I wonder if the modification to the later Apple drivers is required for (some) third party IDE optical drives, but not SCSI.
  2. Panasonic didn't have a Mac driver for these things as far as I know. I played around with a similar model and found that the PC Card SCSI adapter wasn't particularly Mac friendly, so connecting directly to the Mac's SCSI was a must. I'd try FWB CD-ROM toolkit 3.x or 4.x and see if that does the trick. If it still doesn't work, I believe both of those can show you attached SCSI devices and their IDs. You'll want to make sure the DIP switches on the drive are set to an appropriate SCSI ID and that termination is enabled. On my drive, the last DIP switch was on for termination, off to use i
  3. Does it make any difference if USB peripherals are connected during boot? I'm just curious if it's a possible issue with USB extensions rather than the presence of a Cardbus device.
  4. Awesome! Usually I try a keyword search of the web archives. That didn't work so well, so I went to Belkin.com circa 2002 and worked my way back in time until the download page product category selector worked properly. I wasn't expecting the downloads to be archived, but in this case they seem to be. Usually I'll get a filename from a link and then search elsewhere for that.
  5. https://web.archive.org/web/20000829060246/http://www.belkin.com/support/tech/USBdownload.html Looks like that should do the trick
  6. If you can find quality replacements for everything within budget, then go nuts on it.* If I recap mine, I will probably do it in stages to try and identify the failed components, starting with the output filter caps. I may just bite the bullet and pick up an oscilloscope so I can measure ripple and spikes before and after each stage. *By go nuts, I mean replace all of the radial electrolytic capacitors. The ceramics, tantalums, and other solid caps are probably fine.
  7. The capacitors clustered around the output wire harness are the output filter caps and are one of the more likely suspects if the voltages looked okay. In your photo, a bunch of them look domed up - unless it's just a trick reflection.
  8. That's actually something this thread prompted me to look at today -- which components fail in these supplies. Based on forum posts, it seems like output filter capacitors are a common point of failure, along with MOSFETs and sometimes diodes/bridge rectifiers. It seems to me that Apple compromised these machines with the ADC monitor power supply circuitry. The computer's power supply not only has to power the base system, five expansion slots, extra hard drive bays, external USB and FireWire peripherals, but it also supplies power over the stock graphics card's ADC connector - 25v DC total
  9. Negative shutdown IDs indicate that hardware issue prompted the shutdown and -122 indicates the PMU identified an issue with the power supply. Typically it means a bad power supply, but can also be a bad PMU. My Quicksilver is currently dead due to its power supply completely failing. I think I'm going to do an ATX conversion on it at some point.
  10. Have you got system back up and running as it was before you pulled the CPU? If you can boot in OS 9, you could try running something CPU intensive to see if the problem is overheating. I'd do that before going down the path of removing the heatsink and repasting it. It's not a bad idea to do, but I'd troubleshoot elsewhere before going there. I noticed that you seem to be missing the shroud and fan located between the CPU heatsink and back panel shown in this photo of my Quicksilver. I don't know how or if that would affect the machine's behaviour, but I do know that fan management is di
  11. I would pull all but one stick of RAM and see if the problem persists. If it does, pull that stick and try the other one/one of the others. I've encountered many instances where bad RAM isn't immediately obvious in Mac OS 9, but OS X fails dramatically pretty much right off the bat on the same Mac.
  12. Sometimes things get a little cringeworthy on YouTube, don't they? I quite enjoy "Adrian's Digital Basement" and "Retro Man Cave" in their repair and restoration endeavours. Adrian and Neil both seem to appreciate feedback from the community and both develop their techniques over time. Adrian seems to be a whiz with through-hole components, having a lot of experience with Commodore 64 hardware and the like, and Neil has taken on some major surface mount recap jobs in recent months.
  13. Doh! Yup, ROM 2.1 is what I'm after. I misread the readme before my original post.
  14. It could certainly be failed logic board caps, or damage from leaked capacitors. If everything were fine, the 575 board doesn't need a PRAM battery to power on in the CC chassis, so leaving it out should be fine. I certainly can't rule out analog board trouble given the symptoms though. The input and high voltage CRT portions might be functioning, but it may be failing to provide the right voltages, sufficient current, or stable voltages to the logic board. I wonder about the output filtering caps. My first step in troubleshooting would be to stick a logic board or analog board known to b
  15. With the right CF card, it's significantly faster than the hard drive.
