Sound chip for the Personal IRIS

[Scott J Mark]

	In the graphics users' manual, under the section on porting
applications to the Personal IRIS, it mentions that the Personal IRIS
has a sound chip.  I haven't been able to find any other information
on whether this chip indeed exists, and how to use it if it does.
	We have a complete set of manuals, but no index has an entry
for "sound."  Can anyone clear this up please?
