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...

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...

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...

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...

After a two attempts to install 10.3 on the first partition failed, I went with 10.2. So far, using 9.2.2 on the second (larger) partition seems just as quick. I didn't think I'd see any major slowdown but without quantifying the change, I'd say it's unnoticeable.  What was noticeable was the...

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...

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...

The stock drive is quite a noisemaker. I'm guessing a 4200rpm drive? It has been a labor of love to try each OS via network installation (bad run of repository disk image burns). Byrd, out of curiosity, do you use the keyboard? I think mine is a rev2 unit and it was awful when I bought it and...

That's true- by comparison, OS 9 feels relaxed. At least I'm doing this on a HD and not an SSD. I've reformatted about four times by this point. If this was my sole project, I'd go for quantifying performance between the two configurations. As it is, vacation is quickly running out. While I'm...

Thanks, @CC_333. I had forgotten about the OldWorld vs NewWorld boot differences. Convenience is definitely improved, I agree. To run Jaguar or Panther (via Xpostfacto) the OSX install must be on the first partition, which is considered to more quickly accessed than the second partition where...

I recall a LEM article years ago discussing the performance benefits of installing the OS & applications on the first HD partition. With a 60GB 7200rpm drive in my Wallstreet, if I install OS X in the first 8GB but use 9.2.2 more often, would I creating a distinct performance hit for 9?

Thanks, Byrd. I'll try 8.6 (wonderful that it's so easy to do today). I was very surprised at how bloated 8.5 feels, especially when transferring data on the network. The only PPC app that I run with any regularity is Office 98 and I run it under 7.6. Out of curiosity, which apps do you run (or...

While I've been on my classic Mac sort-and-restore binge, I installed 8.5.1 on my 2300c (with 56MB RAM). It was running the original owner's install of 8.1 with lots and lots of stuff. However that System Software RAM total was around 10MB. After I installed the OS and all the usual programs...

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...

It's such a shame that an otherwise clean and functional unit can be brought down by poor plastics. Is it the hinges? It sounds like I won't a use my time fiddling with it if others have had similar issues. Now that I think about it, if it's not the cache it might be a capacitor. Mine worked...

Thank you for your replies. @laporta: by cutoff do you mean the vertical stretch of the viewable image? Those adjustments are internal, unfortunately. It makes me wonder about their in-service life. I suppose they rarely deviated from factory specs when still supported? I wonder if that's also...

Well, that seals it. Off to find a new PRAM battery. If I can get this machine fully sorted then I'll be happier with the state of the collection. Thank you!

Despite using CRT monitors for a while, I'm less familiar with models like the M1212 where geometry adjustments are not part of the OS. I pulled my M1212 out of storage last year and I thought it's operation was normal but now I'm thinking something is up. Before I find plastic adjustment tools...

@Daniël OosterhuisNo, it doesn't have a PRAM battery installed. The board calls for the odd Velcro-in-place (like this one: https://www.newertech.com/products/pram_4_5v.php ) and I recall that those in particular used to leak. Oddly, the double boot is uncommon with mine but somewhat became...

I'm sad/happy to know that I'm not alone with a cranky Kanga. If it's not the RAM, HD, or OS, it does seem to indicate a processor/cache culprit. I had forgotten that the chips are soldered in place. When I opened it up, the comparison of the internals to the 3400 is interesting. The Kanga seems...
