I'm not sure what technical manuals you have, but it is
documented in the HP150 Technical Reference Manual.  I
think that it was part of the keyboard controller chip.
From BASIC, an OUT 27,xx where xx is from 30 to 46 will
generate the 16 tones available (the 27 is correct; I'm
not quite sure about the 30 to 46!).  Anyway, it's rather
limited as far as tone generators go....
