OK, folks, this looks very straightforward now that I know what I'm looking at. Guides already exist for sticking ATX PSU's inside /PFW-enabled Macs, so my investigation and experimentation has come to a close. I will still post an updated pinout guide for the Dyna-Comp PSU later. All I need to...

Eugh! What is that green slime on the motherboard!?

Making some progress in my research about how the Q630 controls power. There is a Power IC on the board which talks to the CPU, which makes logical voltage changes on the 6-pin header. I knew that much just by looking at the board, but not the specifics. Now that I've done some reading, I think...

I know the PCI standard has something like this, dunno about NuBus though.

I'm running the internal header to a DB25 IDC socket, and then stuffing the internal drive into an external case with it's own DB25 IDC socket; that's for the actual project thread.

Well, jt, that certainly would be functional, but I don't wanna see that stuff naked. :p I'll take your advice from before and use one of the rear blanks, or just make a new hole. Also, "blade server" really gets my brain going. That edge connector definitely does mimic how a blade server...

It looks like DB19 Floppy drives are uncommon and expensive, especially Superdrives. Is that true?

Put simply, the custom case I'm building won't have space for any internal drives, just a CF card. All drives would either use the DB25 SCSI port, or the custom DB25 Floppy port I'm making now. They would sit off to the side of a custom vertical case. Why? My Quadra has an 8p8c Ethernet card...

I don't know about an OSX tool, but I know you can do this in Linux too. (Although manually).

Ohh, I see. I got it wrong. It's actually HDI20, not HDI30 (which is for scsi). Comparing these two pinouts, it looks like the HDI20 connector on those drives is not electrically compatible with a DB19 floppy port. http://old.pinouts.ru/HD/macfloppy2_pinout.shtml...

Hmm, I hadn't considered using a Macintosh DB19 floppy drive. Here's a passive DB19 to IDC20 adapter: http://a2heaven.com/webshop/index.php?rt=product/product&product_id=125 (I'm already making DB25 to IDC20 adapters for the conversion, since I already had DB25 cables.) After doing some...

I recently started a Quadra 630 project, and one of the main project goals is to convert the internal floppy drive to external. Someone mentioned: "you could always plug in an external floppy", but (since the Q630 lacks a floppy port) I have not found any external floppy drives that would work...

Jt, as far as I can tell, the conductors on the LB go into the exact same 5V supply layer in the PCB. 100% the same circuit on both ends. I also tested directly from the 5V pin on the ADB socket. I went as far as ripping one of the PSU's apart. Here's where all the 5V lines are coming from, one...

Huh. The two +5VDC lines to the LB aren't actually separate 5V lines... they are 100% connected to the same circuit both on the PSU and on the LB; in other words it is not 10V, but actually 5V spread out over two wires. (By the way, does anyone know how I can clearly notate that in the diagram?)...

I found it using Google Image search and your preview! http://graph.darren-criss.org/2016/01/25/1996-camaro-wiring-diagram-l-f9490e3cf502c93c.gif I don't see any information about that 6-pin header though, just how to wire it up to the 580 analog board.  :( Maybe I can find documentation...

Thanks for the effort there, jt, trying to map out this 6-Pin header is nothing but headaches. I found out that Pin 1, the one I said had +5VDC coming over it, actually has no voltage whatsoever; I just put my test lead one pin over by mistake. I decided to find out where the ADB got it's power...

Trash80, I did find the link (http://member.nifty.ne.jp/frogeye/connector.html#diagram) but it denies all bot access due to it's robots.txt, which means it was not archived like the many other links on that page... How unfortunate. I also found your old thinkclassic posts from 2014, and other...

Yep yep, give it a good wash and pull those components. If you still don't have any luck, I can walk you through testing the PSU. Also, give the PSU a good sniff, does it smell like anything?

You have piqued my interest... If you could patch the Finder to use the UNIX Epoch instead of Apple's home-brewed scheme, that could fix the problem for awhile. It uses January 1 1970 as it's start date instead of 1904, so you would be moving your start date forward by 65 years instead of 56...

Here are my findings! I made a little pinout guide, but it's not finished! I'm going to need some advice on how to proceed, actually. Some things to note about that 6-pin header: Shorting Pin 2 to +5VDC (TRKL) while system is OFF = system power ON. Shorting Pin 2 to +5VDC (TRKL) while...
