Coverage

Partial

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

Completion6%

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.cowboy3p 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 cowboy3p, description "Cowboy Eight Ball", manufacturer "LTD", catalog year "1981".
  • No OPDB record is mapped for this driver in machines/opdb_id.csv, so the name above comes from the PinMAME catalog alone and is unverified.
  • The definition's driver list is exactly the clone tree PinMAME declares under cowboy3p; whether every listed driver really runs on this physical machine is unverified.

Drivers this record holds

  • cowboy3a (1981, LTD, clone of cowboy3p).
  • cowboy3p (1981, LTD).

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 20 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.

ROM sets

Every driver that resolves to this physical machine.

ROM set Description Year Parent Hardware

Parent set: cowboy3p — clones share this definition unless a hardware difference is noted.

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.

Something wrong or missing?

This definition still has 15 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.
