HP-97 decimal point with ghost segment d

[Paul Berger (Canada)]

Do you see a ghost of the decimal point when segment D is lit? if that is true it would suggest a partial sort between the two signal lines. It looks like segments D and H (decimal point) are on separate anode drivers. The two signals are adjacent to one another on the connector between main board and display board but not on the display connector. I suppose it could even be a fault in the display or ROM 0.
