TLDR: Does anyone have, or know where I can get, the schema for the mobo in a q550? Hello, all, and thanks for the forums! I needed a tablet to run streets and trips gps navigation for my work, and a little slate/tablet is perfect and quick to set up in a rental car to do so. I had tried to other tablets with win10, but there is a licensing issue that MS isn't fixing for S&T2013. I do love the features of the baytrail processors, but they only run uefi and installing Win7 is problematic. I hate win10 for conspiracy ad/information tracking reasons. SO, I found a q550 with win7 for ~$110, which is perfect fro what I need. I can certainly use the USB port and external GPS puck for navigation, but I also have come over from Panny Toughbooks, and we just love to rip'm apart and internally mod things. So, I am looking for the schematic for the q500 so I can find an internal serial port to hook my gps engine to. I just love the cleaner setup of having it internal and ready all the time. I haven't received the q550, so I don't even know what the guts look like, yet. I can't wait! Thanks, again!
