 The boards have arrived. I sent Rob Legg his set, next
 I'll send Don Kuenz his pair, and check my email for
 sea moss' mailing address.  I'm not sure, but I think
 James Arthur is out, too busy.  Did anyone I missed
 opt for one?  Any other new customers?

 The RIS-767 files have been updated: Now there's more
 discussion, top and bottom pcb-traces, 2-side assembly
 drawings, plus the orginal four example versions.  The
 DropBox folder now includes Altium CAD files + Gerber.
