Gottlieb Haunted House Full Board Set Repair and Test

Chris Hibler walks through a full repair and test of a Gottlieb Haunted House System 80 board set, covering the power supply, MPU/driver board corrosion cleanup, reset circuit and battery upgrade, RAM socket addition, a slam switch defeat mod, and bench testing of switches, coils, lamps, displays, and sound. He also demonstrates a custom sound test rig built into his Black Hole game. The video is a hands-on technical repair walkthrough rather than industry news.
