The printed switch matrix (2-42) fills the cells for 61 Globe Position #1, 71 Magnet Over Ring and 77 Globe Position #2 with the same "Opto, Typically Closed" halftone it uses for the ten ramp and popper optos beside them, and a mechanical connected-component sweep of all 64 cells at 600 dpi confirms the shading is present on exactly those thirteen cells and absent everywhere else.

For 71 the switch-locations parts list agrees independently, giving an A-14231 LED and A-14232 phototransistor pair. Pinned PinMAME treats them differently: recomputing jdGameData's inverted-switch mask {0x00,0x00,0x00,0x02,0x00,0xf8,0x6e,0x3e,0x7f,0x00,0x00,0x00} bit by bit gives normalized addresses 32, 54-58, 62, 63, 64, 66, 67, 72, 73, 74, 75, 76 and 81-87, which covers ten of the thirteen shaded cells but leaves 61, 71 and 77 uninverted.

The manual is physical-construction ground truth and pinned PinMAME is emulator-normalization ground truth, and the two disagree about whether a recreation must invert the state it reports for these three. 61 and 77 carry an A-16598 part number that discloses no construction either way, which weakens the manual side for those two but not for 71.

Resolving it needs a LibPinMAME harness trace against a legal jd_l1 or jd_l7 ROM observing the idle public state of 61, 71 and 77 with no ball on the globe and the crane parked.

What would settle it

run the repository's LibPinMAME gameplay harness against a legal jd_l1 or jd_l7 ROM with 61, 71 and 77 watched, reading their idle state with no ball on the globe and the crane parked and their transitions as each is made; independently, a photograph or parts breakdown of the A-16598 assembly would fix construction for 61 and 77, which the printed part number alone does not disclose.

PinMAME source

Pinned PinMAME's jdGameData inverted-switch mask normalizes the five JUDGE drop-target switches 54-58 (column 5 = 0xf8, bits 3-7), which is the treatment it gives optos elsewhere on this machine. No source read here discloses opto construction for them: the switch-locations parts list gives a single assembly number A-16486 with no LED or phototransistor breakout, unlike every genuine opto row on the same page, and the printed switch matrix leaves all five cells unshaded.

Pinned PinMAME's own jd_handleMech asserts each of these switches while its target is DOWN, which is the sense a normally-open target switch would report and therefore the opposite of what a normally-closed opto plus emulator inversion would produce. Either the A-16486 target really is an opto assembly whose construction this manual does not spell out, or the mask's column 5 is wrong.

Resolving it needs a LibPinMAME harness trace observing the idle public state of 54-58 with the bank reset, or a photograph of an A-16486 target assembly.

What would settle it

run the repository's LibPinMAME gameplay harness against a legal jd_l1 or jd_l7 ROM with 54-58 watched, reading them with the JUDGE bank reset and again with each target knocked down, or obtain a photograph of an A-16486 target assembly showing whether it carries a discrete LED and phototransistor pair.

VPX script
PinMAME source

Three matrix addresses are printed "Not Used" with a blank part number on both the switch matrix (2-42) and the switch-locations parts list (2-43), yet the location diagram printed on that same parts-list page still draws a callout for each of them: 28 on the crane / Magnet Over Ring assembly, 32 on the plastic orbit ramp beside the globe, and 65 on the right-hand ramp.

The other six "Not Used" addresses (45, 46, 47, 48, 78, 88) have no callout, so this is not a habit of the drawing. Conversely item 67, a fitted opto with a full A-14231/A-14232 part pair, has no callout anywhere in the diagram. The retained known-working table binds the L-1 ROM and drives all three: it asserts 28 while the Globe Magnet holds a ball, pulses 65 from a right-ramp trigger whose own comment reads "Opto Right Ramp Entrace (Not used?)", and pulses 32 from its ramp-entrance trigger under a commented block recording that the ramp opto's address "Position changed between L1 and L7 ROM Revisions" — SW32 at the ramp entrance for L-1, SW67 near the top of the ramp for L-7.

Pinned PinMAME corroborates 32 twice over: jdGameData's inverted-switch mask normalizes address 32 as though an opto were fitted there, while jd.c's own #define block marks 32 unused and names 67 swLRampEnt. The coherent reading is that the location drawing and the L-1 firmware come from an earlier design revision in which 28, 32 and 65 were fitted and 67 was not, and that production deleted them and updated the parts list but not the drawing.

That reading is not proved, and it matters to an author: a recreation bound to jd_l1 must decide whether to wire three addresses the production manual says do not exist. Resolving it needs a photograph of an unrestored production playfield at those three positions, or a LibPinMAME trace comparing what jd_l1 and jd_l7 actually read.

What would settle it

a photograph of an unrestored production playfield at the crane / Magnet Over Ring, orbit-ramp and right-ramp positions showing whether a switch body is fitted at each, together with a LibPinMAME gameplay-harness trace run twice — once on a legal jd_l1 ROM and once on jd_l7 — watching 28, 32, 65 and 67 under the same driven inputs so the revision difference is observed rather than inferred.

Gi string order script vs manual

VPX script
PinMAME source
Human review

Pinned PinMAME publishes the five general-illumination strings as zero-based addresses 0-4 taken from the five low bits of WPC_GILAMPS in order (src/wpc/wpc.c), and the repository's WPC-DCS controller profile records that public address N is the manual's printed string N+1. The manual identifies its five printed strings by wire colour: String 1 Wht-Brn, String 2 Wht-Org, String 3 Wht-Yel, String 4 Wht-Grn, String 5 Wht-Vio.

The retained known-working table binds public GI 0 through 4 to collections it names GIstring1 through GIstring5 and annotates them, in that order, wht/vio, wht/grn, wht/yel, wht/org and wht/brn — the printed order reversed, agreeing only on the self-symmetric middle string. The two claims cannot both be right.

Emitter coordinates in this definition follow the script's runtime binding, because a known-working table is the runtime authority for what each public address actually lights, while the bulb types, connector pins and wire colours follow the manual under the profile's printed-order rule; if the script's annotation is correct then those two halves are attached to each other wrongly.

Two further details fit neither reading cleanly: the table's collection for public GI 4 contains backglass objects only, while the manual gives printed String 5 a playfield drive connection and no backbox column, and the table's collection for public GI 3 contains two playfield objects and no backglass, while the manual gives both candidate strings entries in both columns.

Resolving it needs a LibPinMAME harness trace driving each GI address in turn against a legal ROM, or a photograph of the J120/J121 harness on a real machine.

What would settle it

run the machine's own general-illumination test on an unrestored unit and record which of the five printed wire colours (Wht-Brn J-120-7, Wht-Org J-120-8, Wht-Yel J-120-9, Wht-Grn J-120-10, Wht-Vio J-120-11 on printed 2-44) lights at each step, since printed 3-10 draws one unnumbered representative string and cannot say which triac serves which string; pairing that against a LibPinMAME harness trace driving public GI 0-4 in turn on a legal jd_l1 or jd_l7 ROM closes the mapping from both ends.

Mechanisms

Logical assemblies with their actuators, sensors and observed behaviour. Click a chip to jump to the address it refers to.

Deadworld rotating globe

mechanism.deadworld-globe

Motorized

A gearmotor (14-7985, assembly A-16478, mounted under the playfield) rotates the Deadworld globe above the playfield. The globe carries three ball slots. Pinned PinMAME models it as a free-running 0-100 position counter that advances one step per mech tick while solenoid 6 is energised and wraps at 100, asserting Globe Position #2 (switch 77) over steps 0-10 — the window in which a captured ball sits under the crane and can be lifted, which is what jd.c's own comment on swGlobe2 says. Globe Position #1 (switch 61) is the ball-present state at the globe: jd_stateDef's "Planet" step holds a ball on switch 61 with the Arm Magnet as its release solenoid. The retained script implements the same shape differently, rotating the disc by a fixed angular step per timer tick and asserting switch 77 when the angle brings a loaded slot to one of three drop positions. Neither position sensor is a point on the playfield surface; both are angular sensors on the globe assembly.

Drives
6Globe Motor

Deadworld crane arm and magnet

mechanism.deadworld-crane

Motorized

A second gearmotor (14-7989, assembly A-16678) swings a crane arm out over the globe, and an electromagnet on the end of the arm (A-12158-1, assembly A-16769) picks a ball off a globe slot and carries it back to the playfield. Pinned PinMAME models the arm as its own 0-100 position counter advancing while solenoid 4 is energised and asserts Magnet Over Ring (switch 71) over steps 0-10, the window in which the magnet is above the ring and a ball can be picked up or released. Releasing the magnet drops the ball, which then breaks the Crane Exit opto (switch 62) on its way back into play — the driver's ball simulator sequences exactly that as Planet, In Claw, Dropped. Switch 62 is the only reliable way to know a ball has left the mechanism, which is why the retained script's own handler for it is commented "*critical* to keeping track of balls". Whether a further switch reports that the magnet is holding a ball is unresolved; see conflict.l1-era-switch-fitment for matrix position 28.

Five-target JUDGE drop-target bank

mechanism.judge-drop-targets

Drop Target Bank

Five drop targets spelling J-U-D-G-E sit in a single left-to-right bank across the middle of the playfield. Solenoid 5 (Reset Drop Targets, A-16947, under the playfield) raises all five at once; solenoid 10 (Trip Drop Target, A-16445, under the playfield) pulls only the centre "D" target down, which is what opens the subway beneath it. Pinned PinMAME's jd_handleMech keeps a per-target up/down flag and asserts each switch while its target is DOWN, so a recreation reports the switch closed for a dropped target rather than for a struck one. The retained script drives the same five targets through its own DropTarget helper objects (DT54-DT58) and implements ResetDrops and TripDrop to match. The physical construction of the A-16486 target switch is not disclosed by any source read here, and PinMAME normalizes all five addresses; see conflict.judge-drop-targets-normalized-without-opto-evidence.

Subway under the D drop target

mechanism.subway

Other

With the centre "D" drop target down, a ball shot at the bank enters a subway under the playfield. Two rollovers track it on the way through — Subway Enter 1 (switch 37) at the start and Subway Enter 2 (switch 38) part way along, both marked †Located Under Playfield — and it comes to rest in the Left Popper, an opto-sensed vertical up-kicker (switch 73, solenoid 2, assembly A-16580) that fires it onto a habitrail. Pinned PinMAME's own ball simulator sequences Subway, Subway, Subway Popper, Subway Habitrail in exactly that order, and gates entry on the "D" target being down through its custom key condition.

Drives
2Left Popper

Sniper Tower right popper

mechanism.right-popper

Kicker

A ball resting on the Right Popper opto (switch 74) at the top right of the playfield is kicked back into play by solenoid 3 (A-15769) onto a wire ramp. Pinned PinMAME's ball simulator names this shot the Sniper Tower and routes its exit to the left inlane.

Left ramp diverter to the Deadworld globe

mechanism.left-ramp-diverter

Diverter

The plastic orbit ramp that runs up the left side and round past the globe has a solenoid-operated diverter at the top (solenoid 11, A-16802, under the playfield). With the diverter at rest the ball carries on through Left Ramp Exit (switch 64); with the diverter energised it is sent through Left Ramp To Lock (switch 63) and onto the Deadworld globe. Pinned PinMAME's ball simulator encodes exactly that branch, with sDiverter selecting the "Towards Planet" alternative from the Left Ramp state. Which opto reports the ramp entrance differs between ROM revisions; see conflict.l1-era-switch-fitment.

Drives
11Diverter

Six-ball trough and ball release

mechanism.trough

Kicker

Six balls rest on trough optos 81-86, with Trough 6 (86) at the eject end nearest the right shooter lane and Trough 1 (81) at the drain entrance. Solenoid 13 (AE-26-1500, assembly A-16765) ejects the ball resting on 86, and Top Trough (87) reports the ball leaving; the retained script's handler kicks from 86 and pulses 87 in the same event. All seven positions carry an A-16926 phototransistor and A-16927 LED per the switch-locations parts list, so a recreation asserts the public switch when a ball is present.

Drives
13Trough

Right and left shooter lanes

mechanism.shooter-lanes

Kicker

Judge Dredd has two ball-launch lanes. The right shooter lane is the normal one: a ball ejected from the trough rests on switch 41 and solenoid 8 (A-14525) launches it. The left shoot lane is a second, mode-specific launcher — the retained script calls solenoid 9 (A-16936) the KickBack and the manual calls it Left Shooter — fed from the Air Raid ramp habitrail and resting on switch 15.

Left and right slingshots

mechanism.slingshots

Other

Each slingshot assembly (A-14369-L and A-14369-R) carries a kick switch (SW-1A-114) and a separate score switch (SW-1A-120), which is what the "(2)" printed in matrix cells 51 and 52 records; both switches feed the one matrix address. The retained script's slingshot handlers pulse 51 and 52 and fire coils 15 and 16 in the same event.

Three-switch captive ball

mechanism.captive-balls

Other

A captive-ball lane on the right side of the playfield is instrumented at three depths: Captive Ball 1 (switch 26) nearest the player, Captive Ball 2 (switch 53) and Captive Ball 3 (switch 68) furthest in. Harder shots push the captive ball deeper and register more of the three in sequence, which is exactly how pinned PinMAME's ball simulator chains them (Captive Ball -, Captive Ball /, Captive Ball |). Switches 26 and 53 are 5647-12693-19 rollovers and 68 is an A-14227-15 target switch; none of the three is an opto.

Advance Crime three-bank standup targets

mechanism.three-bank-targets

Other

Three standup targets stacked vertically on the right of the playfield share the single matrix address 18. The manual's own switch-location diagram draws the 18 callout three times against one A-14227-15 part number, and the retained script instantiates three separate hit targets that all report public switch 18. A recreation therefore needs three physical targets but only one controller input.

Lower flipper pair

mechanism.lower-flippers

Other

Two FL-11629 flippers on Fliptronic circuits (A-15205-R-2 right, A-15205-L-2 left). Each has a separate power and hold winding: the ROM energises the power winding on the cabinet button opto (112 right, 114 left), then drops to the hold winding once the end-of-stroke leaf switch (111 right, 113 left) closes. The retained table runs Const UseSolenoids = 2, so the ROM drives the coils directly rather than the table simulating them.

Upper flipper pair

mechanism.upper-flippers

Other

Judge Dredd is a four-flipper wide-body: an upper right flipper (A-15205-R) sits below the Sniper Tower shot and an upper left flipper (A-16976-L) beside the Deadworld globe. Both are fitted, so all four upper Fliptronic switch positions and all four upper flipper solenoid addresses carry real hardware and none is repurposed. The upper right flipper is the one circuit that uses a different coil, FL-11630 (Red) rather than FL-11629 (Blue). Pinned PinMAME agrees: jdGameData declares FLIP_SW(FLIP_L|FLIP_U) and FLIP_SOL(FLIP_L|FLIP_U), so core_getSol routes public 33/34 through the upper-right coil path and 35/36 through the upper-left path, and the retained script binds sURFlipper to its right-hand upper flipper object and sULFlipper to its left-hand one.

Connections that exist in copper, not in the ROM. These fire whether or not a game is running.

Coverage
partial - source-derived recreation knowledge requiring validation

Overview

Legacy evidence identifies this candidate as Bally (1993). 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.

  • games/jd.json#/_source/confidence_notes: High confidence on switches/coils. No Const sw* definitions — switches identified from _Hit/_UnHit subs, Controller.Switch() calls, and PulseSw calls. Lamp IDs from Lampz.MassAssign() calls; descriptions inferred from VBScript comments and object names. Flashers (coils 17-28) use SetLamp with 100+ lamp IDs (117-128). Slingshots (coils 15-16) commented out in SolCallback — handled by VPX directly. Trough uses 6 switches (81-86) with a custom implementation (not bsTrough). sw87 is pulsed on trough eject as shooter lane confirmation. Flipper coils use framework constants (sLRFlipper, sLLFlipper, sURFlipper, sULFlipper). Upper flippers present (4-flipper game).

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?

ROM sets

Every driver that resolves to this physical machine.

ROM set Description Year Parent Hardware
jd_l7Judge Dredd (L-7)
Bally L-7 game ROM, the pinned catalog's clone-tree parent and the last factory revision. Judge Dredd's Deadworld ball lock was deactivated for production, so L-7 locks balls virtually rather than diverting them onto the globe; the playfield hardware is unchanged.
1993—identical
jd_l6Judge Dredd (L-6)
Bally L-6 game ROM; a later firmware revision of the same physical machine.

1993jd_l7identical
jd_l1dJudge Dredd (L-1D MOD)
Community MOD of jd_l1at by KoP, per pinned driver.c's own comment.
1993jd_l7identical
jd_l1atJudge Dredd (L-1AT MOD)
Community MOD of L-1 for the aftermarket Deadworld hardware modification, per pinned driver.c's own comment. It runs on the physical machine and changes no controller address.
1993jd_l7identical
jd_l1Judge Dredd (L-1)
Bally L-1 game ROM. This is the driver the retained known-working VPW table binds to (cGameName = "jd_l1"), and its own script comment records why: L-1 still runs the Deadworld ball lock as originally designed, physically diverting balls onto the rotating globe, while later production code virtualises the lock. Same physical machine and the same I/O inventory.
1993jd_l7identical
jd_d7Judge Dredd (D-7 LED Ghost Fix)
L-7 with the LED ghost fix; a display-driver change only.

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.

    Source locations

    148-page scan of the Bally Judge Dredd operations manual with an Adobe Paper Capture OCR layer. Printed pages 2-40 through 2-45 carry the lamp matrix, lamp locations, switch matrix, switch locations, solenoid/flasher table and solenoid/flasher locations; printed 3-3 carries the dedicated-switch wiring and circuit; printed 3-10 carries the general-illumination circuit. The OCR text layer scrambles every multi-column table on those pages and was never used for a value.
