    Belkin F5U015 USB to SCSI adapter drivers

    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.

    https://web.archive.org/web/20000829060246/http://www.belkin.com/support/tech/USBdownload.html Looks like that should do the trick
  3. 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.
  4. 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.
  5. 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 totalling more than 5A. Even if you're not powering an ADC monitor, I'm sure that compromises had to be made in regards to the design of the PSU, and it seems like a fully loaded system would push the limits of the power supply even when new. I'm not suggesting that refurbishing the power supply is a bad idea; I'm still considering it myself, but I think it may provide some context as to why these power supplies seem to be failure prone. My Quicksilver has had the power supply replaced at least twice at this point-- the last one had a sticker on it from the local AASP when it was installed in the late '00s, and the current dead one was a used pull I bought a couple years ago.
  6. 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.
  7. 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 different between Mac OS 9 and OS X. On my machine, the fans seem to run full speed in OS 9. While booting up OS X, the OS seems to take control and adjust fan speed. Have you already reset the PRAM and NVRAM? How about the PMU?
  8. 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.
  9. 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.

    Radius SE Accelerator 16 ROM dumps

    Doh! Yup, ROM 2.1 is what I'm after. I misread the readme before my original post.

    Color Classic Analog Board problems

    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 boot in there, but I realize not everyone has one sitting around. Sometimes it's possible to spot logic board cap damage in photos, oftentimes it's hidden, but posting a photo of the board probably wouldn't hurt.

    Trying to do 8.5 clean install in 1400cs

    With the right CF card, it's significantly faster than the hard drive.

    Trying to do 8.5 clean install in 1400cs

    That isn't what I meant, but is also a very worthwhile accessory for your 1400. I use one to move data back and forth from my modern Macs quickly and easily. I just format a CF card as HFS+ and I can pop it into a USB CF card reader on something else. Here's what I use in place of the hard drive: This looks like it would be functionally equivalent since the model I have seems to be replaced with a dual slot adapter: https://www.amazon.com/Compact-Flash-Merory-Laptop-Adapter/dp/B00S6GIHS2 I think @Cory5412 and @Byrd are on the right track when it comes to burning speed and image integrity. I had similar issues making a good 8.5/8.6 install CD and I suspect a bunch of the images out there are corrupted. NOTE: some of these IDE to CF adapters have a full 44 pin male connector on the IDE side. My 1400 has a 43 pin female connector, so you may need to clip the corresponding pin from the adapter. You'll see the omitted pin on the back side of my adapter near the middle of the IDE connrctor. Note the white arrow pointing to pin 1 of the IDE connector on the front of my adapter. It's furthest away from the hinge and LCD on the PowerBook, on the top row.

    Radius SE Accelerator 16 ROM dumps

    The inits I've tried definitely break things badly. I suspect that the ROMs are inaccessible via software as the Radius documentation indicates you need to send the accelerator to them or replace the PROMs to upgrade.

    Trying to do 8.5 clean install in 1400cs

    In my 1400, I ended up using a 44 pin IDE to (single slot) CF adapter and a 4GB SanDisk Extreme IV CF card that I had kicking around in my camera bag. I currently have it formatted as a single 4GB HFS+ partition running 8.6 and it's performing quite well.
