AND-30C

K desce AND-30C nemám dokumentaci, schéma získáno metodou zpětného inženýrstvý.

Deska AND-30C byla součástí SAPI-IPS jenž obsahovalo desky JPR-1Z, AND-30C, RAM-64 a RFD-Z.

Stručný popis funkce.

Deska alfanumerického displeje AND-30C je postavená na obvodu MC6845, vzhledem k použití bodovému kmitočtu 10.8MHz, velikosti znaku 6x12 bodu a RAM o kapacitě 2kB bylo možno dosáhnout na standardní TVP s video vstupem 80 znaku na řádek a max. 21 řádků. Font znaků je shodný s deskou videa AND-1Z. Znakový generátor je řešen pomocí EPROM a jde osadit typy 2716 nebo 2732. Pro znakový generátor při plné znakové sadě je potřeba 4kB. Při vhodném nastavení propojek a osazení 2x 2732 je možno mít dvě znakové sady, přepínání znakových sad se bude provádět pomocí některého signálu MAP nebo S. Jako u celé sestavy SAPI-IPS co nebylo potřeba, k provozu sestavy to není osazeno. Při překreslování DPS jsem zanesl většinu úprav, co byla provedena na DPS, proto je ve schématu i na DPS to „u“ v názvu.

Adresace desky

Adresný dekodér je řešen pomocí PROM a umožňuje adresaci v celém rozsahu RAM s krokem 2kB. Taktéž je možno použít stránkování.
