I am working with an IBM Monochrome "Black and White" Parallel card that
is showing a double image. I noticed that the 106 / 16+ tant cap at the
top left near where C1 / U47 is printed was broken off the board so I
put in a new one. There was no change. I tried another cap, no
change. I removed the cap entirely, no change. I am looking for a
schematic/docs/suggestions.
It looks something like this:
