Hi Dave, I am making progress. Since you seem to remember where things might be on Gateway Tower, maybe you can answer this one. I put the Braille Lite on a port. It is along the outside of the case and is a male plug, but it runs lengthwise on the plate instead of crosswise. My son has perfect vision but the back plate says nothing. I am going to install Windisk and will have to tell it what port the BLT is on.. Any idea what port it would be? Thanks, Sue
