Woodstock Display Problem

[cjmcc]

I've attached a photo of the display showing 908172635.4

Going left to right, you can see the decimal point is ambiguous - several look possibly lit.
The 9, 0, 8, and 1 are reasonable, but the 7 has an extra segment 'almost' lit, as do the 2, (6 looks OK because that segment is supposed to be lit), 3 and 5 (which look like a 9 and a 6).
   

For reference, the on-line emulator HP29u gives a much cleaner look.
