Jed,
	I have been asked by Bob Flanagan and Tim Hubberstey to hook the 
Marble Madness in Bobs lab so that we can switch the operation from stereo
to mono audio. So, Hubberstey went and picked up the latest version of the
System I manual, marked it up and asked me to cover it. But what Bob has is
not an SA II like he has marked up. It is not even an Audio Reg. III.
What he has is an audio regulator two that has been modded. I think the audio
section is untouched in terms of the original PCB layout design. My question
to you is, is this audio considered to be "stereo"?

				Thanks in advance
