I've ranted once or twice about not liking the sound package on Whoa Nelly. That Melody would sound more Melodious with a real set of chimes. The synthetic sounds - especially the non-chime sounds (special effects, voices, music) were just .. annoying on this particular machine to me.
A while back I started looking into adding chimes, based on comments from Greg and Dennis; and from what I saw in the manual. This thread is about making this happen - nothing too special, but perhaps encouragement for others.
Starting with the manual:
We open up to the coils listing; and find 26-1200 coils specified. No diode.
Actually, I lie a bit - Chas at Stern gave me the answer before I saw it in the manual. (ahem)
This also identifies the expected wire colors - which I ordered from BAA.
The optional chimes, if attached, hook up to the NODE 11 board.
Identifying this board would have been more challenging if Stern didn't include this with the docs:
Especially, since it appears that the board already has connectors attached, and there was no obvious "NODE 11" text.
