The project has been continuing in spirit. I learned that life is a shitball and you can either eat it or throw it at someone else. There will be more time, and I'll make more money which I can spend on this hobby, which is quickly turning into a preservationist effort. In fact I just filed for...

I finally got around to setting up the Quadra 800, and the PSU has released magic smoke after a few boots! I’ll look into cramming an ATX PSU into this thing. Pulled the PSU apart and noticed some darkened pins... and on the other side is a current mode controller with a hole blown through it...

If you can't get the machine to boot, then the only ways to power it off externally is to either use the reset button on the back (next to the monitor video output port), or unplug the PSU. The hard drive could be unformatted, disconnected, dead, or missing. Thankfully, the Quadra 630 uses...

I now have the 950 booting happily, and I think I have found the cause... I am so pissed at myself. You may have seen that photo of a little clip on a blue oscillator I was looking at. Well I left that in there during testing! Oh good lord! :scrambled: When I went to test the PSU recently, I...

I will be checking the PSU! I removed everything, including the motherboard, for inspection; everything looks fine. The scene in here is depressing. I miss my cat.

This has not been a good month for me. First my poor cat Linus is hit and killed by a car last week, and now the Q950 I picked up from our dear Nuvision has died! This Quadra 950, a workhorse at Nuvision Graphics for who knows how many years, is now giving no signs of life, and I don't know why...

Hey all, I've recently started setting up a Quadra 950 with SCSI2SD. I have encountered an issue where connecting a CD-ROM drive causes the machine to SadMac on boot, sometimes showing a movable mouse cursor for a second beforehand. This occurs regardless if the CD drive is connected internally...

A SCSI2SD and a ton of caps have been delivered! This LCII has a chance for life! The SCSI2SD will be going into the Quadra 950 or the 800 for now.

Linus loves blunt objects mashed into his face. It's a cat thing. As you can see I went with the Wiss snips, and they work quite well. The project is kind of slowing down again, due to other things occupying my time. It will be done soon, I'm just trying to think of case designs that will...

Big boy. Seeing what's on it, looks like this Q950 used to be stocked with a PPC card, plus some Radius and Daystar hardware.

I ordered new caps for the LCII and the PSU, which is putting out funky voltages: Quadra 950 won't boot from hard disk and says "You need a PowerPC Mac". I swapped in the PPC upgrade from the Quadra 800 but nothing changed. I guess I may be wiping that drive, but not before I rig it up in an...

I recently got involved in reverse engineering the power architecture of the Quadra 630, in order to do an ATX PSU conversion. One thing I noticed is the large differences in component values between models, and implementations. Now I am very interested in finding out what the differences are...

It begins!

Okay, here's the "stupid simple" layout I threw together in Illustrator. You may notice the PSU has switched sides... this is because I wanted it on the bottom of the case to make it more bottom-heavy. Because of this, the LB must get flipped around as well, to keep the power cables accessible...
