Pictures of the logic board would help. Have you looked at it yet?

Thanks, it's certainly motivating to hear that. The ATX PSU adapter is coming together now... I hacked apart one of the Q630 PSU's for the main socket, and I'll continue to use that PSU to figure out what else goes over that other small cable. I think I'll desolder the socket for it, and break...

Hehe, yeah, that is my backup plan exactly! It would be very convenient, but if you want to switch resolutions to the point that you need to adjust the adapter (DIP switches on the thing), you would have to open the case to do so. My "plan" (in quotes because there isn't really one!) would be to...

That and I'm seeing it says "ATA/CAM Compliant: no", and is in removable disk mode. Pretty sure both of those could be an issue. Looking for a working card now. This one comes in fixed disk mode, and should work: https://www.amazon.com/gp/aw/d/B00APVL9GS

Well, that didn't work out too well. The CF card formatted and mounted using a Disk Tools 1 floppy... then it stopped working. HDT and Drive Setup can scan and identify the device just fine, but now formatting fails and it won't mount anymore, even on my MDD. HDT now says it has a 1024GB...

The PSU sure is a puzzler to me, but I am anything but an electrical engineer. The 12-pin plug was easy to map out, but the 6-pin header is another story. I was only able to identify the 5v TRKL line... It is on the 6-pin header, among other things. I have no idea what's going through the rest...

The video output went nuts and the chip crashed, but all is well after a reboot. I have partially mapped out the power architecture on the logic board. There's some odd stuff on there! For instance, there are whole areas that are completely disconnected from the PSU on the board, with...

Doing some late-night open testing with the volt meter. It was a great rear-end clencher when I shorted some of the pins on the Valkyrie chip with the test leads. :D

Is that the 5vFP (Flea Power) 2A output on the Dell PSU? I'm pretty sure it must be switched to this mode, and cannot output normal voltages while doing so. This begs the question, when does the Q630 need the 5v 0.08A TRKL output?

Suppliers like Digikey and Mouser. For reference they're 3x derated. Some initial work! Starting to understand the wiring harness and Q630 PSU. I found a Dell SFF PSU that looks to be a great replacement candidate. The 5v Trickle output will have to be replicated somehow. Lucky me, I actually...

The board also needs $40 in new caps. I don't have the cash for that or much else :p I'm just using what's readily available to me.

This is an anchor thread for a Quadra 630 project I am starting, which will receive periodic updates as the project progresses. The primary goal of this project is to build a custom, minimal vertical case for the Quadra 630 logic board. The case will not support internal expansion except for...

Is this it? I don't have a box, just the DVD.

You are correct about the matching banks. Falcon is referencing the Dual Channel memory system. At a minimum, you should have one module per bank (pair of 2 slots) installed. If you're unsure, just put a module in the top slot, and the other module in the second-to-last slot. If you open it up...

I love what you're doing, and yes- I think you should consider keeping it closed source. Your time and effort are worth something. For reference, the power key on typical ADB keyboards is not "soft"; it is directly wired to the PSU through a dedicated pin. This is why you can't simply map a key...

A Quadra 630. Looks like it was actually an 800k image, and I was using a 1.44MB disk; which is why my 1.44MB disk wasn't being accepted. I still can't explain what's going on here though.

I was in the middle of using Disk Copy 6.3.3 to image a floppy, inserted a double sided disk and... Well, it didn't like the disk and rejected it, even though it was double sided. When I tried again, this happened: The system froze at that point. Notice how it says to insert "Macintosh HD"...

Illuminati confirmed. Works perfectly.

This is more a jury-rig than a hack, but still cool! I did not expect this to work. I have a RoDime R0652 pulled from a Mac SE that died one day. I decided I needed to see if it still worked. The only 68k Mac I own is a Quadra 630... so there's no opportunity for an internal connection there...
