Mit der Videoerweiterung läßt sich das Grundsystem zum 6k-System erweitern.
Die Beschreibung eines passenden SCART-Kabels ist bei Ulrich Zander zu finden: https://www.sax.de/~zander/z9001/tp.html#TV
Für den Speicherbereich zwischen %6000 und %7FFF gibt es einen separaten Adressdekoder auf der Videoerweiterung. Damit neben der Bildschirmsteuerung die Tastatur weiterhin funktioniert, muß das /CS3-Signal zum Tastaturlatch (V40098D, Pin 1 und 15) aufgetrennt werden. Die Tastatur bekommt ihr Auswahlsignal (/KEY) nun von der Videoerweiterung. Ein Rückbau ist durch Einsatz einer Steckbrücke…
