This is a bug. This didn't show up while testing on the VAX since the VAX doesn't have DL device support. The latest code fixes this problem and will now allow up to a total of 16 TDC controllers and/or DL lines. Now that you can get beyond your initial configuration steps I'm still looking for feedback about any device driver issues that may exist with various PDP11 operating systems when accessing TU58 devices.
