I've got a PP2 cockpit and did the mod as discussed here with the schottky (1n5817), a cap (47uF), and a ds1220ab. Yet it is not saving scores. I assume the mod works on PP2 just the same, right? I used an electrolytic for the cap - I assume that's ok? Tried 2 different ds1220's so unless the run was bad that should be ok. The band on the schottky is on the Vbatt side.
The battery holder was eliminated from the circuit before I got it, but I assume any battery elimination that was done wouldn't have involved a destructive modification of the circuit.
Anyone have an idea of what might be wrong or what I should check?
