1. Still getting duplicates. 2. As for the modern replacement for a DVI, it seems that we're working on a quicker/smaller tennis shoe network. Certainly good ideas all, but there is very little software that actually takes advantage of 80 columns and 25 lines for the M100. Somewhere in the thread I thought there was mentioned of a version PI used with mComm? Has anyone look into the PI Zero W? I have been trying to find more detailed specs (measurements) as the PI Zero line does have a HAT compatible 40 pin bus; https://cdn.sparkfun.com/assets/learn_tutorials/6/7/4/PiZero.png . Seems to me there might be a way to have a PI Zero plugged into the M100 BUS and leave it there. Ports (HDMI, USB) could be extended to allow access through the M100 case. Unplugged it acts as an internal TPDD and plugged in it's all a desktop. Don't know if Raspbian would be able to handle it, but there has to be version of Linux that could.
Just a thought, GregS <><
