Coverage

Partial

Real evidence exists, but authoring requirements are still missing or in conflict. Verify before shipping a table.

Completion13%

Progress is derived from the fixed author-readiness requirements. It helps rank unfinished work, but only a 100% author-ready definition passes the publication gate.

Recreation notes

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

Coverage: partial - machine identity plus candidate-only I/O attachments. Playfield devices, wiring, mechanisms, and behavior are evidenced only as unverified candidates.

This record was promoted from the generated catalog stub stub.pinmame.nugent by the catalog-wide identity pass of 2026-08-29. The promotion resolves machine identity and carries the catalog's residual driver grouping over unchanged, the platform and device attachments below were added by the 2026-08-29/30 candidate passes and assert nothing beyond candidate provenance. Every requirement in the definition's coverage.missing is genuinely outstanding.

Identity

  • PinMAME catalog: root driver nugent, description "Nugent", manufacturer "Stern", catalog year "1978".
  • OPDB record G5VWL-MLRjl (IPDB 1687) names this machine "Nugent" (Stern Electronics, manufacture date 1978-01-01); the resolved identity rests on the agreement of the PinMAME catalog and this reviewed mapping.
  • The definition's driver list is exactly the clone tree PinMAME declares under nugent; whether every listed driver really runs on this physical machine is unverified.

Drivers this record holds

  • nugent (1978, Stern).
  • nugentfp (1978, Stern, clone of nugent).

PinMAME source contract (candidate)

  • The pinned PinMAME source declares nugent at src/wpc/stgames.c:193 with machine module by35_mST100s; no platform is declared (no reviewed profile covers that module yet).

VPX script candidates (candidate)

  • 1 retained community table script(s) declare this machine's driver; their extracted switch/lamp/solenoid/GI candidates are carried as 17 candidate devices. When curator work weighs sources, a retained script outranks emulator-derived candidates for runtime semantics, but every device here is still a candidate until a known-working table is verified against this exact physical machine.

What a curator must establish next

Controller platform from the pinned PinMAME driver source; full input, output, and display enumeration with semantic names; physical wiring and polarity; mechanism inventory and behavior; variant differences across the clone tree; recreation knowledge from a manual, schematic, or known-working table; runtime provenance; and a normalized spatial placement for every physical device. No manual, schematic, or runtime-harness evidence is retained for this machine yet; the candidate sections above are the only retained I/O evidence so far.

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.

This definition still has 14 unmet requirements, listed under Coverage above. Fixes belong in the definition itself — editing on GitHub forks it for you and opens the pull request.

Cite a source for anything you change — a manual page, a line in a working VPX script, PinMAME source, or a reading from the machine's own service menu. Claims without provenance cannot be validated.
