3 unresolved conflicts

Sources disagree here and nobody has settled it. Treat these addresses as unproven.

Outlane special insert side transposition

Affects
lamp 15
Disagreeing sources
Operator manual
VPX table
VPX script

The two outlane Special inserts are placed on the opposite side of the playfield from the outlane each one is named for, and the disagreement is inside the retained table rather than between the table and the manual. The manual's lamp list names public 15 "Rt. Out Special" (A5J2-14) and public 31 "Lft.

Out Special" (A5J2-15), and the retained table's own outlane switch objects are sided in agreement with those names: the left outlane sensor normalizes to x = 0.052 and the right to x = 0.852. But the table's Light objects invert it, placing L15 at x = 0.051708 on the left and L31 at x = 0.852858 on the right.

The table is therefore internally inconsistent about one physical location, exactly as Stern Ripley's Believe It or Not! turned out to be about its pop bumpers. This definition preserves the observed object coordinates rather than swapping them, because swapping would assert a coordinate no source observed for the insert of that name; the disagreement is recorded here instead so the placement is not read as a settled fact.

Resolving it needs this game's own printed playfield insert map traced to A5J2-14 and A5J2-15, or a lamp test on real hardware. Note the same shape may affect public lamps 10 and 58, whose emitter y-coordinates are likewise swapped relative to the switches of the same names; that pair additionally sits inside conflict.right-side-target-upper-lower-transposition and is not independently resolved here.

What would settle it

this game's own printed playfield insert map traced to A5J2-14 and A5J2-15, a photograph of an unrestored machine's A5J2 harness at those two pins, or a lamp test on real hardware observing which outlane insert lights while public 15 and public 31 are driven in turn.

Right side target upper lower transposition

Affects
switch 12
Disagreeing sources
Operator manual
VPX table
VPX script

The two right-rail standup targets are labelled the opposite way round by two parts of this machine's own manual. The printed Switch Assembly Self-Test table (PDF page 22) reads "12 LOWER RIGHT SIDE TARGET" and "15 UPPER RIGHT SIDE TARGET", and Figure V (PDF page 23) independently draws circle 15 on the upper target and circle 12 on the lower one.

The Playfield A6 switch matrix sheet (PDF page 46) labels the same two matrix positions RIGHT SIDE UPPER TARGET at 12 and RIGHT SIDE LOWER TARGET at 15, and the retained known-working table follows the schematic, naming its upper object sw12 and its lower object sw15. The two agreeing manual sources are used for both the label and the placement, which means this definition deliberately places switch 12 on the table object named sw15 and switch 15 on the object named sw12.

Resolving it needs a photograph of an unrestored machine with the two target harnesses traced, or a stuck-switch self-test on real hardware.

What would settle it

a photograph of an unrestored machine with the two right-rail target harnesses traced back to the A6 switch matrix, or closing each of the two targets by hand on real hardware during the machine's own Switch Assembly self test and reading which number the score displays report for it.

Aux lamp 100 left rollover fitment

Affects
lamp 100
Disagreeing sources
Operator manual
VPX script

Public lamp 100 is auxiliary circuit U4 output 3 through SCR Q18 to A9J3-11. The A9 schematic prints that pin's function as N/U and the A9J3 harness plug table on the same sheet gives the pin no wire, so on the manual's evidence nothing is fitted. The retained known-working table nevertheless binds public 100 to the two left-hand rollover buttons of switch 1, which are the only two of the seven rollover buttons on the machine with no lamp circuit of their own, and Figure V draws them with the same star-burst symbol as the five that do.

The address is left unused with no spatial key rather than resolved either way; a LibPinMAME harness trace observing whether a legal flashgdn ROM ever drives public 100 outside the lamp self-test would settle whether the ROM believes the circuit exists, though only a machine or a factory insert map can settle whether a bulb does.

What would settle it

run the implemented LibPinMAME gameplay harness against a legal flashgdn ROM and observe whether public lamp 100 is ever driven outside the lamp self test, then a photograph of an unrestored machine's A9J3 harness at pin 11, or a factory playfield insert map reaching that pin, to settle whether a bulb is fitted behind it.

Left four-bank drop target

mech.four-bank-drop-target

Drop Target Bank

Four drop targets running up the left side of the lower playfield, printed A at the bottom through D at the top, with one shared reset coil and no individual down coils. Home state is all four up; a target's switch closes as it falls and opens again when the bank is reset, so the bank can only be restored as a whole. Two rebound rubbers beside the bank are a separate two-contact address, public switch 5. Each target has its own insert lamp - public 9, 25, 41 and 57 bottom to top - and the bank carries a 5X multiplier lamp at public 60.

Upper-left three-bank drop target

mech.three-bank-drop-target

Drop Target Bank

Three drop targets on the upper-left playfield with one shared reset coil and no individual down coils. Three arrow inserts in front of the bank - public 8, 24 and 40, printed #1, #2 and #3 Drop Tar. Arw. - show which target is currently worth the award, and public 56 is the bank's 4X multiplier.

Right in-line drop target bank and back target

mech.in-line-drop-target

Drop Target Bank

Three drop targets in line up the right side of the playfield, so the ball can only reach the second once the first is down and the third once the second is down, with one shared reset coil. Behind them sits a standup target, public switch 28, which is exposed only when all three have dropped; the retained script models it as an ordinary standup with no drop mechanism. Public lamp 30 is the bank's extra-ball insert.

Top single drop target

mech.single-drop-target

Drop Target Bank

A one-target drop bank at the top right with two coils rather than one: an AO-27-1300 reset that raises it and a CE-31-2000 pull-down that drops it on ROM command. No other target on the machine can be lowered by the ROM. Home state is up; the switch closes while the target is down. The retained script drives both directions from these two addresses (DropSingleUp on public 9, DropSingleDown on public 12).

Centre two-way saucer

mech.centre-saucer

Kicker

A saucer in the middle of the playfield with two kicker coils that eject the ball in opposite directions: an AO-27-1300 kick-up that throws it back up the playfield and an AO-29-2100 kick-down that returns it toward the flippers. The saucer switch reports ball-present and both coils are gated on it in the retained script, which clears the switch before either kick. Its value inserts are public 12, 28 and 46 (10K, 20K and 30K) plus public 44 for extra ball, and the 2X and 3X saucer arrows are the auxiliary-board lamps 117 and 101.

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 (1980). 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.

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?

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.
