[Coco] Re: CoCo Orchestra-90

I did a quick scan-thru of the O-90CC manual, and something I found 
which seemed disappointing was no mention of how (or if it were 
possible) to control the cartridge from BASIC, ML or OS-9.

Does anyone know if this is possible? Is there an "unravelled"-style 
book or document describing how to do this? Did Rainbow or another 
magazine ever publish anything about such access?
