Pins & wiring

Pinout

Choose the exact wiring. Pin numbers follow its stated view; a schematic does not establish physical positions. Check your exact device before wiring.

Dark pinout view

What the status labels mean

Confirmed: Recorded research passes agree within this variant; this is not independent human review or hardware validation.
Single source: Only one underlying document, or one pass, supports this assignment.
Device-specific: Supported for the named equipment or wiring only. Check your device’s manual.
Unverified: Missing or conflicting evidence. Do not wire from this row.
Not connected: The source explicitly says NC, no contact or no pin for this wiring.

Only pins 1, 2 and 7 are established for this family by the cited documents; the remaining pins are listed as unverified rather than copied from the Macintosh Plus table.
Partial variant: pins 3, 4, 5, 6 and 8 have no rows because no cited document gives them for this family (see P210 unverified[]).
DV16 and Inside Macintosh: Devices only establish pins 1, 2 and 7 for these families; the Macintosh Plus table (HW10) was not extended to them.
DV16 states pin 7 is not connected on these models, but no full table for them was retrieved.
