I’m having trouble getting a Sonnet Crescendo PCI 1GHz up and running in my Power Mac 8600 (Kansas) or 9600 (Tsunami). An 800MHz version of that card in the same Macs works fine. Symptoms: - The Mac freezes while loading the Sonnet extension(2.3 or 3.1). - With the Sonnet extension disabled...

I turned on the SE/30, and got a "disk initialization failed because the disk is locked" message before the desktop could load. Clicking "OK" leads to an endless loop of this message. This is in the setting of working on a floppy drive. The SE/30 had worked all day. I had just installed a...

I was finishing up minor work on a good 1.4MB MFD-75W floppy drive. When I inserted a disk to test my handiwork, the upper read/write head fell off the mechanism. The epoxy holding the head in place was in brittle, easily broken pieces. I looked at a number of nonfunctional drives, and saw...

I spent the last few days working on the stack of eBay crusty junk (the seller's very accurate description) 1.4MB floppy drives in my possession. I'm going to show pictures of the one that was in the worst condition. There was so much corrosion on this one that the carriage mechanism was...

I have a Daystar Turbo 040 that I have used in the past with my SE/30. Looking at the card for the first time in 13 years, I see that it is set to run at 40MHz (it has a 20MHz crystal), but the cpu is a 33MHz XC68040RC33. Did the 40MHz cards come overclocked from the factory?

I have a Powerbook G4 that won't boot with the RAM cover installed. The Superdrive makes noise and the shift lock key turns on and off when pressed, but there's no other sign of life. PRAM won't zap - nothing. After some experimentation, I have become suspicious that the problem is what I...

I would like to secure a Twinspark PDS adapter to the metal frame of my SE/30. Are screws or plastic clips used to accomplish this? Does anyone know the specs of the screws or clips?

I have a Radeon 8500 AGP connected to a Dell monitor at 1080p 60Hz by VGA. The DVI jack is not connected to anything. The card believes in both OS9 and OSX that there is a second VGA monitor attached, but there is only one VGA port, and the DVI port does not have the four analog pins on it to...

This is a question regarding past experiences — none of my current SE/30’s exhibit this behavior. Back around 1990, the SE/30 I used in the chemistry lab in college developed this problem. The mouse responded slowly and erratically enough to be useless, and the clock advanced very, very fast...

I have a PowerBook G4 500 (M5884) that is having a logic board keyboard issue. The tab, command, left arrow, up arrow, and delete keys (and probably some others) do not work. I have tried multiple keyboards, and all work normally with a different PowerBook G4. I have tried heating the logic...

I am wondering where people obtain parts for repairing PowerBooks.  My sources have been: 1.  eBay (of course) - a mixed bag, but tonyzz has been reliable consistently. 2.  www.PowerBookmedic.com - running low on supplies.  I‘ve had mixed results from them, but have found customer service to...

I could use some advice regarding what steps to take in the following problem: I have a TiBook G4 1GHz board in a banged-up case that I want to put into a new case (sold as new by Sunshine Express on eBay). In the old case, both audio channels work.  In the new case, only the left channel...
