PDP 11/05 - looking for help - looking for Jorg Hoppe?

Jorg Hoppe:

I am the proud owner of an old pdp11/05.  I does not have a M9970 (nor can I find one).  So I cant do 20ma/rs232 output.  I read in somebodies note about jumpers @W1 and W2 on the M7261F that I have.  Apparently cutting one of these disables the onboard uart and will allow me to put in a serial card.  I cant find the jumpers.  Nor can I find a print set.  Any suggestions?
