To my knowledge this is the only course of its kind that has ever been taught, I had to write all of the slides from scratch since I couldn't find any lecture notes to base mine on.
Sadly I've graduated and moved on to other things, but am still actively working in the field (see my recent conference talk https://recon.cx/2015/slides/recon2015-18-andrew-zonenberg-F...)

U5 was a ROT13(SCTN) but your answer is close enough to get credit.
U13 was a ROT13(SGQV HFO pbagebyyre), you can tell since it connects to J2. I don't recall what U1 is but you can ask marshallh (retroactive.be) since he's the guy who designed the board.
