PC speaker?

[03sjbrown at bsuvc.bsu.edu]

Is anyone aware of a tracker program that will use PC speaker?

I know a program called Impulse Tracker does but I'm looking for some
type of program that is PC speaker native (something old). 
Something that's going to put out really nasty 1-bit sound
but not a bunch of channels mixed down to PC speaker quality
(if I want that, I can listen to AM radio). 



Also, can anyone point me in the direction of schematics for an 
analog noise gate?
