Anyone know the pinout of the front panel header on the Dell Motherboard in Arcade Legends. This is the first version. I am not sure of the Mobo version. I don't think it is the GX-150

I need to reconnect the power switch and the power LED. They came unplugged when I removed the CD-ROM drive, and the CD-ROM drive blocked any view of the pins.

try pins 3 & 5 as your on/off.
and pins 7(-) & 9(+) as your power led.

That looks like a standard pinout, but with the silkscreen reversed.

I tried a bunch of combos and do deal. Ugh. At least I fixed the problem of the crackling audio out.
 
I heard back from Chicago Gaming company. Yeah it is completely non-standard, the one connector you connect diagonally which explains why the header pin was bent.

I should also document that I replaced the two electrolytic caps connected to the audio out jack. That got rid of the cracking and popping on the output.

The originals were Nichicon 105C 220ohm 25v. I replaced them with a Nichicon 50V 220ohm and a 100V 220ohm (Chinese from a Bob Roberts kit) that I had on hand.

I had some XICONs that were 25v 220 ohm but in my tester the ESR was reading high on them so I went with the bigger caps.
