Yup, I'm using a DL11-W. No, I do not have a KW11-L in 1C. God only knows if
this system ever had one there, but I don't have one in any case. Maybe it
never had one, or maybe it did and fell out years before I got the system.

I don't :)

AHA! Now THAT is information I'd like to know about. It sounds like if you
don't have an M787 and want to use the clock on the DW11-W, you need a
jumper to complete the grant chain over 1C. Sounds like I need that info!
Anyone know what the magic jumper is from/to?
