The CD-ANA-2 board is the audio, video and power board for the front-loading NeoGeo CD. It is equivalent to the NEO-CDA_board (see for power section schematic) on top-loading systems.

ON button circuit

The circuit is basically a divide-by-2 with power on reset and debouncing.

POWER is constantly at 5V when the power plug is connected.

VCC goes to 5V when STARTUP goes low.
