American Girl Pinball Teardown 5: New microcontroller

Dismantling "The Flip Side", a 1:5 scale pinball machine created by American Girl (the doll company). This is the 5th video in a series where I disassemble and reverse engineer this cool little machine. In this video we remove the original microcontroller from the playfield circuit board and use a Teensy microcontroller to drive the backbox score display and playfield LEDs using the playfield circuitry.
