RE: HP-97 decimal point with ghost digit d
Segment d lit does not lead to a ghost digit to the decimal point (segment h). Displays are ok as the phenomen appears on the other calculator as well - I only transferred the main board. Display PCB and printer PCB both left inside.
So my conclusion is it is surely caused by (something on) the main board. But no idea what.
BTW: Card reader is still to be tested and adjusted (gum wheel is already repaired) as soon as I have time and patience to do.
