Stan Dunten at Dartmouth College came up with the idea for the "oscilloscope" display.  He has long wanted a program which will indicate whether an AppleTalk node is responding reliably or not.
 
Thanks, too, go to Paul Hartenstine and Ted Painter who implemented a preliminary version of this program as part of a CS project.  Their prototype wasn't fast enough for production use, but it showed that the idea had heart.  It really wow'ed the Repair Shop technicians.

Thanks to R. Fronabarger, who wrote the original Styled Text help dialog code.

Thanks to Chris Johnson for the use of his Popup menu control CDEF.

Thanks to Richard M. Siegel for the use of his "UGenericPrint" routine which took care of all of the "gory details" in using the Printing Manager, and to Matthew Xavier Mora for compiling this valuable piece of code into his USENET Macintosh Programmer's Guide, making it readily available.

Finally, thanks to Paul DuBois and Owen Hartnett for creating TransSkel, a public domain "skeleton" Macintosh program.  It helped to know that I didn't have to write the whole thing from scratch.
