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

The model should be “1055CM". I used to support a bunch of these. Not a bad plotter. Definitely preferred them to the Versatec plotters they replaced. I suspect HP won’t support it. I ran into that problem with an earlier model, then to my surprise I found a local outfit that would repair
