Yup. (And BTW the baud's not jumpers, it's the dials.)

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'.

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