Copyright infringement.
Bill, it would appear that the posting of the Hewlett-Packard and especially the Tektronix test equiment manuals on that site are in violation of U.S. copyright laws. You might check with Agilent and Tektronix and get written permission to use that material so you don't get the University and your own personal tooshie in a sling over that. Schools are not the least bit exempt from copyright law, although a lot of the ones I've worked with in the past have thought otherwise.
