By type, the board carries 4 connectors, 3 switches, 2 fuses, 2 diodes and 1 capacitor.
From the project
Squeak Check is a standalone board that interfaces with Midway's Cheap Squeak Deluxe and Sounds Good arcade game sound boards.
SQUEAK CHECK! — Midway sound board bench tester — REV E.5 By Ethical Paul =========================================================
WHAT IT TESTS ------------- Verified against the original Bally/Midway schematics (Spy Hunter, Rampage/Star Guards and Sarge manuals). All three boards share the same J1/J2/J3 pinout and the same command interface (4 sound-select bits + SIRQ strobe, 2 status bits back):
