Marc, Thanks! I think I can work with those and get something out of it. given the width of 5-3/4" (at its widest point?) and length of 6" I can scale the rest. Like you said, Xerox put a lot of engineering design into the production version, compared to the original Engelbart 'Demo' chordset (that someone has now wired up to an iPad): https://valerielandau.files.wordpress.com/2010/04/chorded-keyset-to-ipad.jpg Steve
