Hi David, been going over this schematic for the umpteenth time and still not sure. As you say there is + and -5v digital + and - 5v analogue.
Pins A26 and C26 show different voltages.
A26 shows +5VA
C26 shows +58v
I traced the line from V1212 cathode side it shows continuity with both pins.
Looks like the +5VA on the drawing has been marked wrong (A26).
