The video power board of the VT-102 terminal. There are for adjustment pots to control display characteristics. The bottom one adjusts "linearity". A small adjustment was made.
This picture shows the text size after the linearity potentiometer adjustment. The top and bottom screen text is now the same size. It is likely that there has been some video capacitor decay since the terminal was assembled, but only a small adjustment was needed.
