NEO-CDA board

Audio/video and power boards in top-loading NeoGeo CD consoles.

=NEO-CDA3-1=



Carries a DAC, LC78815 CDDA DAC, 2 quad op-amps, a CXA1645 video encoder, 2 7805 regulators, a LM2930 8V regulator and various transistors.

Connectors, from left to right (need exact pinouts):
 * YM2610 to YM3016 serial data
 * CDDA left, right, clock
 * RGB video and sync
 * CD 5V, 10V CD, 5V logic, Ground

= NEO-CDA4-1 =



Same as the NEO-CDA3-1, but with only one dual op-amp and a second LC78815 instead of the YM3016 (which isn't needed anymore with boards using the chip, capable of outputting LC78815 compatible serial streams).

24M08 regulator instead of the LM2930 ?
