3 ROM sets resolve to this machine. Clones share the definition unless a hardware difference is listed.

Controller platform
pinmame.bally

PinMAME already reports logical active state. Do not invert again in the table — normally-closed is a physical fact recorded per switch, not a runtime transform.

Recreation notes

Working knowledge that has no schema field yet — edition differences, tuning values, pitfalls.

Coverage
partial - source-derived recreation knowledge requiring validation

Overview

Legacy evidence identifies this candidate as Bally (1981). The information below is preserved for recreation work but is not automatically treated as validated physical-machine fact.

Playfield devices

Switch, lamp/GI, and controlled-device candidates are in the adjacent machine definition. Source-specific implementation notes are retained below.

Custom mechanisms

No custom mechanism conclusion has been validated. Manuals, schematics, PinMAME source, and gameplay evidence still need to be checked.

Ball-state transitions

Ball paths, trough ordering, locks, kickouts, and causal transitions have not yet been normalized. Relevant source notes follow under Evidence notes.

Controller interactions

Controller callbacks and bindings are candidate evidence only until reconciled against PinMAME and physical documentation.

Service and setup information

Unknown; locate operator/service documentation.

Timing and tuning observations

Source timing values may describe a particular VPX implementation rather than physical hardware and require review.

Recreation guidance

Do not treat this partial definition as a complete authoring specification. Resolve every coverage requirement and conflict before promotion.

Evidence notes

  • platforms/bally.json#/coils/1: Unbound legacy outputs record c_flipper_lower_right was retained as a migration note only.
  • platforms/bally.json#/coils/2: Unbound legacy outputs record c_flipper_lower_left was retained as a migration note only.
  • platforms/bally.json#/coils/3: Unbound legacy outputs record c_flipper_upper_right was retained as a migration note only.
  • platforms/bally.json#/coils/4: Unbound legacy outputs record c_flipper_upper_left was retained as a migration note only.
  • games/centaur.json#/coils/12: Duplicate binding label candidate Right 4 Drop Target "4" (bottom) differs from Right 4 Drop Target "3".

Unresolved questions

  • Is the I/O enumeration complete for every supported physical/controller variant?
  • Which inferred VPX behaviors reflect real hardware, and which are table-script conveniences?
  • Are all mechanism home states, sensors, motion constraints, and ball interactions documented?

Sources

  • legacy.game.centaur: games/centaur.json at the pinned migration revision.

Evidence

Every claim above traces to one of these. When they disagree: a known-working VPX script wins on controller addresses and causality, the manual wins on wiring and construction, pinned PinMAME wins on emulator routing and display layout.
