  Does anyone have a M7800 (DL11) set for 9600 b N71 or
N81 jumper'd with
 the default address for use as a serial terminal interface? 
Yup. (And BTW the baud's not jumpers, it's the dials.)

...
  I understand the other jumpers on the card, but the
address and vector
 jumpers confuse me. 
Join the crew... :-)

The simple rule on the DL11 is that vector jumpers are the inverse of address
jumpers: for the vector, jumpers are 'in' for '1', and for the address,
they
are 'in' for '0'.

...
  I think for use as a simple serial terminal interface
I need to jumper
 "in" *A9, A7, A5, A4, A3* ... correct? Vector jumpers *V6, V7 "*in" .

You mean for the console, right? (All DL11's are 'simple serial terminal
interfaces' ;-).

The jumpers you give are for DL11 #1, address 776500, vector 300. For
777560/60 (standard for the console), you want A7/A3 and V4/V5 'in'.
