The source code of curses.c contains the following:

/*-------------------------------------------------------*
* CURSES.C: Copyright (c) 1987, Allen I. Holub. *
* All rights reserved. *
*-------------------------------------------------------*
* *
* Adapted for OS9 from an article in DDJ 7/87. *
* R. Waggoner *
* *
*-------------------------------------------------------*

If someone knows the whereabouts of Mr. Waggoner, maybe we can consult him?
