Abstract

1. Una placa de circuito impreso multicapa que tiene conductores impresos y agujeros pasantes metalizados, estando un cierto número de los agujeros destinados a recibir las patillas de componentes electrónicos, sirviendo los conductores y los agujeros formados sobre y en la placa para interconectar los componentes de un ordenador que comprende un microprocesador, medios de memoria, elementos lógicos y componentes electrónicos que están todos interconectados por líneas que forman un canal interno, comprendiendo los elementos lógicos circuitos de ataque de línea que funcionan en respuesta a señales transmitidas por líneas escogidas del canal interno para gobernar otras líneas que forman un canal de entrada/salida, caracterizada porque están previstos unos medios sobre la placa de circuito impreso para interconectar una serie de conectadores de entrada/salida, cada uno capaz de recibir otra placa de circuito impreso y de ser conectado, estando un primer grupo de conectadores interconectados únicamente a la líneas del canas E/S y estando interconectados un segundo grupo de conectadores a algunas de las líneas del canal E/S así como a algunas de las líneas del canal interno. 2. Placa de circuito impreso según la reivindicación 1, caracterizada porque la serie de conectadores de entrada/salida comprende 8 conectadores. 3. Placa de circuito impeso según la reivindicación 1, caracterizada porque el primer grupo de conectadores es más importante que el segundo grupo de conectadores. 4. Placa de circuito impresa según la reivindicación 1, caracterizada porque comprende, además, medios de conexión modificables en función de las diferentes combinaciones de microplacas de memoria utilizadas. 5. Placa de circuito impreso según una cualquiera de las reivindicaciones 1 y 3, caracterizada porque la serie de conectadores comprende ocho conectadores, comprendiendo el primer grupo de conectadores siete conectadores, y comprendiendo el segundo grupo de conectadores un conectador. 6. Una placa decircuito impreso.
