Went to work today, completely redid all the controller ports connection which was a major PITA, but glad I did it. Instead of having multiple wires, I just daisy chained the 3.3v, 5v, and ground wires across the ports. I also used color-coded wires this time and used a thinner wire for the data lines. I think it looks a lot better now. Went ahead and wired the WASP back up again too, so got that working. I noticed rumble isn't working, and it turns out 5v isn't getting to the other side of the board. No continuity from the power connector to the relocation point for the controller ports or the disk drive pins. Might have to manually wire that up but I'll have to troubleshoot more tomorrow and see if I can identify where the problem is. I'm not sure if 5v is rerequired for the memory card to function so it may or may not be necessary (edit: it's not). By way, is it normal for the voltages to read lower than normal while the cube is running? Plan for the weekend is getting the memory card wired up as well as the bios battery. Might hook the screen up too at least to just test it. Will do some more cable organizing when I put it back in the case but I want to finish all the work on the bottom side of the board first. Not sure where I'm going to place the regulator in the case yet so I don't know how long to keep the wires for it. Anyway here's the current state of the project.
