I've search the forum but can't see this discussed anywhere. I have a dead MD3000 that is out of warranty.  I'd be willing to buy replacement parts EMM, power supply etc but I can't figure out what the problem is. I'm trying to track down the password reset/debug cable, but can't seem to find a part # on Dell's web site.  Does anyone know the pin out of the cable or where I can get one?  

 

Would it work to use an old style PS/2 --> serial converter with a null modem cable, or is the debug/reset cable pinout different?

 

Thanks for any advice.  I'll give Dell a call on Monday, but I was hoping to work on this over the weekend if I can make up a cable myself to do some troubleshooting.
