From the project

Sharp MZ-80K Replica Public

A simple audio/video board which provides a collection of different outputs.

For audio, line out as a 3.5mm mono jack and an LM386 based amplifier with a volume control for a small 8 ohm speaker.

For video, a DIN connector for BBC/Amstrad type RGB cables (e.g. to SCART), 9 pin D-Sub (as green and c-sync pin 7) and a basic composite output.

Some previous trimmers used for testing composite have been left on and marked as DNP.
