I ran across a few new gamecube development motherboards and am wondering if there is a pinout diagram anywhere for the power supply for them. main board labelled: Orca (J) 2.0A HSGD-00-0019-4 023 Daughter boards mounted on it: HSGD-00-0021-2 017, HSGD-00-0020-3 017, Power supply plug appears to be a 6 pin green connector. Wondering if I can adapt a pc power supply to fire it up with. Also has 2 risers for memory cards that go onto the motherboard and the gpc-2000 usb interface that plugs into one of the memory card slots. Other than a case, power supply and the sdk software... any ideas how many more parts are needed to actually use the things for anything useful? Thanks for any insights or any help.
P.C PSU converted for use with an ORCA: http://assemblergames.com/forums/showthread.php?t=5937 ...You need to post pics before I can describe what else is missing.
pictures of the board Here is the board and the USB adapter closer shot of the mainboard I could probaly pick up a dozen of these if they were useful. All are new in the box. Each one has the usb adapter and this motherboard. Thanks for the help!
Hmmm, looks like you are missing the power supply interface board that plugs underneath the mainboard... ...Here's a link to pic which shows the bit you are missing: http://assemblergames.com/forums/showthread.php?t=4782
Looks to me like the power supply board also runs a drive controller and the game controllers. Com port looks like it comes off the main board but couldn't tell with 100% certainty from the pictures. Seems like one could pretty easily wire up a power supply to this plug and get it fired up if I knew what the power requirements were on this plug. But it might be a lot harder to get the controller plugs wired in unless the plug shown below here could be patched into a ribbon cable off a regular game cube with the help of a little adapter. That would depend on whether the power supply board does anything other than perhaps supply some power to the controllers. This is assuming of course that the power supply board is hard to come by which I am just assuming and that the unit could be used for something without the drive, again assuming the drive and the controller are difficult and/or expensive to come by.
I'd also be interested in one, depending on the price of course. Please let me know if you decide to sell some. Thanks.
If somebody could measure the voltage that goes to the green plug on that board I would hook some power up to mine and see if it will function at all without that power supply board. Who knows, it might fire up enough so that it had some limited functionality. Would appreciate it very much. roger
The green plug isn't a recognised power input. ...Nothing is normally plugged into this socket. ...I'm not saying you can't put power in here, I'm just saying its not recognised.
Hmmmm... appears to be some sort of probable power input. Feel like throwing a tester on it to see if any power back feeds into it? If nothing does I will try and educated guess and see what it does.
I see this ending poorly for the little orca board... Is there any chance of comming up with the power board from your supplier? Generally dev hardware is built on the edge of tolerances, and they don't do well when you stick 12 volts down the 5 volt rail...
If it is an output think that power backfeeding into it might fire the board up? I may be thinking too simplistic here. Tester here shows that 3 of the 6 plugs are dead ground... every other one... and the other 3 have some resistance between them and ground.
All you can do is try it and watch out for the bang / smoke / success (delete as appropriate) ...Btw a diode is a one way valve, ouch.
lol.. quite right with the diode comment. Figure if I am going in blind I will probably hit each power plug with a 5v and if it feeds to anything something might fire up.. such as a fan... or if it supplies juice to the battery.. anything obvious anyway then guess from there. If I am lucky it will feed directly back to the input pins from the connector on the back and not have anything in between.
Well, the more I probe the board with an ohm meter, the less I am convinced that is a power input. Anybody feel like putting a voltage meter on the regular power supply board and map which pins on the connector that plugs into the black connector have power to them and what the voltages are? Seems like that would be the safest way to see what it does when I try powering it up.
