The Donkey Kong cocktail table

This is a Donkey Kong cocktail table in the exact same cabinet type the Radar Scopes were put in. Here is a picture (189 K) of this machine with the top open. Except for the slightly larger monitor frame the design is not different from the Radar Scope cabinet insides. (both pictures shown by permission of Ed Mandy, Minnesota, USA).

Donkey Kong: Sprite is at the wrong location

(Submitted by Texasmame in the VAPS Forums)
Cocktail DK plays normally but with DK in lower left of screen for P1
and in normal position for P2 but Mario starts
two girders too high for P2.
Power tests good. Ribbon cables OK.
So: What section or chips are responsible for the *positioning* of sprites?

solution:
It turned out that this was the LS86 at 5H on the CLK board
