Sorry, I don't think I have them. I never did much with DEC hardware that 
modern (I am more of an Omnibus/Unibus person). I do have a BA23, and I 
guess I could pull the switch PCB and see what's going on.

If the scrematics are on the web anywhere, I'd be happy to take a look 
and see what's going on.
