Hey guys, need some guidance.
I got a Druin board (Thanks Retro-active!) and in order to wire it up, it requires a 5-volt power source, this is where my ignorance kicks in.
I have an IPac-4 as well as a HAPPs 3" trackball, would either one of these have that Power Supply, or would I have to get it from the PC?
If I have to get the 5-volt from the PC, a few questions:
*What color wire is the 5-volt on the PC's drive connectors?
*Would I need to use the PC's drive connector ground or can I ground the Druin board elswhere (IPac-4??)?
BONUS QUESTION: LOL, sorry, In this review by "Dr. D" http://arcadecontrols.com/arcade_druin.shtml , he mentions that he "adjusted the key speed in Ikari Warriors to get one twist to turn the correct distance", how would I go about adjusting the key speed?
Thanks gents!

If your IPAC-4 is already hooked up then it has a +5v input. You should be able to use that same wire for the +5v for your Druin board. If you want to use a different wire and need to get it from your computer, the red wire from the driver connectors is 5v. I believe you can ground whereever you want, but you might want to read other replies about that.

Use a wall wart that has a 5v DC output. Cut off the end and use the 2 wires. Many times, people have tons of them laying around:

Thanks for the reply fatty (and I mean that in the most respectful sense ;D ) I dont have my IPac-4 sitting here in front of me, but looking at this pic, I cant seem to find the 5 volt lead on it:

If you can locate it on there, let me know, thanks!

One thing you will want to get is a multi meter. You can use it to check the voltages on the power supply of your PC, continuity and other things depending on the complexity of the meter. For your +5v supply you can use a drive power connector from the PC's power supply. Here is the pin out of the connector in order.
Yellow +12v
Black 12v Ground
Black 5v Ground
Red +5v
I wouldn't take too much power from a USB power source as they are normally limited to around 300 - 500 milli-amps of power draw, I don't remember the exact limit off hand. An example of this is Groovy Game Gear's LED-Wiz, there is a limit of the amount of milli-amps you can draw without supplying +5v from an external source. The drive power source will have plenty of amperage to draw from.
A lot of these simple questions can be answered buy using the forum search. There is a link on this page and every forum page at the top just above the links to the various boards here.
Sorry I can't help you with your bonus question.

Thanks Kay for the reply,
Funny you mentioned this, because I was actually under the desk with my multimeter between posts and came to the same conclusion (Red = 5 Volts).
Good stuff!

The pin header on the IPac has two +5v pins:

Thats for an IPAC-2, you think that would matter?

Yellow +12v
Black 12v Ground
Black 5v Ground
Red +5v
Just as a side note.
This has always thrown me... Whay would they put the lower voltage on the red wire with the higher on the yellow.
I know its been that way for donkeys years but it just seems so counter intuitive. :dunno

*sigh* It seems you are correct and I'm an idiot! :hissy: I usually try not to post when I'm not certain, but I thought I was in this case. It seems the IPAC/4 must get power from the PS2 connector. I think that means you're back to the drive connector (red).
