Yeah, the mockingboard manual says as much and even lists the phoneme codes (though the SC01 data sheet goes into better detail about all the parameters).  I've read in a few places that some folks have decapped the sc01 but nobody has posted their findings.  If the part is out of print, out of stock then why are the IP holders content to let the memory and workings of this obsolete tech fade into total obscurity?  It would be nice to have a full simulation for a change.
