I took my little monitor apart as well as one of my Color Classics. The amount of wires in there scared me away. I wouldn't know what to do. However, my new mini CRT is shorter than the one in the color classic, but the board and nobs for adjusting the picture geometry are connected to the back of the tube, so it's 3x wider at the end. I'm afraid I just don't know enough about how these work for me to even attempt a CRT upgrade. I guess I was hoping it'd just be a couple wires to swap.
