Here is what I have learned.  The Dell 490 and Dell 690 have a mother board connector that looks like this. [IMAGE] The "proper" cable looks like this.  I put proper in quotes because I'm not sure if this is the correct cable but its currently working for me. [IMAGE] When connected it looks like this. [IMAGE] The connector base is larger than the male connector, but it fits around the pins and is wired correctly. Part numbers used: Memory Card Reader : Dell TH661 TEAC CA-200 Cable: Dell WD912   SDHC and SHXC compatibility.   Initially after installing the card reader it would not read any of the newer formats and it the firmware of the reader was version 4.0. Searching google I found a few post saying that I need to update it to 4.08 for compatibility.  After making the upgrade I was able to now read the new card formats.   I have not tested write speed to the cards.  Here is the link to the R176603 firmware update. [URL]    Thanks everyone for there help.   Anyone need a card reader? I had to buy 4 of them to figure this out  
Hello everyone.  Blast from the past question here.  I am trying to add a media card reader to an Dell Precision 490 box, and I'm having no luck locating factory part numbers for the media card readers or the cable that was used to hook it all up.   I do know the Dell GH483, HX835, and 0R6401 cables do not fit the mother board.   I have visually confirmed the Dell Precision 690 use the same connector on the motherboard but I have been unable to locate part numbers for that system also.   Thanks for any information you can provide.
