Carte "Audio-Board"
Cette carte fait passer la sortie audio (en provenance de la carte "Extension Bus") par un préamplificateur (optionnel), un potentiomètre de volume, et un Amplificateur mono. Le haut-parleur (4 ou 8 ohms) peut être branché directement sur "Audio OUT".
Schéma d'implémentation
Note: Le PréAmplificateur a été remplacé par une carte Shunt.
