Hmm, the info on the 30V stuff was from a spec sheet filed away with other documents I have from the 2002 season, but looking through the CD archives it seems that they were wrong (or perhaps for the wrong version of the 883).
This thread seems to explain things a bit, while
this thread leaves things somwhat in the air.
Incidently, Sanddrag, your first link goes to info on the 884, not the 883.
This is probably the link you meant.
