Does the system provide a way to play a (continuous) sound of fixed frequency until turned off?
The Macintosh plays asynchronous waveforms, so this can be implemented.
If so, it might be worth to support the CRT routines (see crtdjgpp.h and crtlinux386.h for examples of other platform-specific CRT extensions).
I can put it on my todo list (if I find the time for it, later this year).
