I don't think so. The manual came with my /260, which seems to be an
upgraded /100. It has only a PMAG-AA card inside.

The maxine manual does not mention any monochrome monitor, only color
and greyscale. All of these are described to use 3W3 connectors.

The manual claims it to be BNC. My machine came without this cable, I
had to solder it myself. The monitor-side connector is sold as 75 ohms
BNC, it's apparently a quite common part of TV equipment.

Again, the manual says so. The monitor of my machine is a VR419-DA.
I can look for the complete list of supported monitors in the manual
and post it here if you want.
