8 - bit Microprocessor
( 1976 )This printed circuit board contains primitives and basic elements of the 8-bit microprocessor family.
Built using NMOS technology, the maximum clock frequency of 1 MHz this 40-pin PCB is 1 MHz. Apart from the microprocessor, it contains an interface adapter for asynchronous communications (MC6850), a peripheral interface adapter (MC6820), a 128×8 bit RAM chip (MCM6810) and a ROM chip (MCM6830) for storing the monitor program.
The PCB has several sockets for connecting additional components.
This module had need of another module for keyboard, audio cassette, 7-segment LED, RS-232 interface and teletype terminal connection.
El circuito impreso contiene una serie de zócalos disponibles, capaces de alojar componentes adicionales.
Este módulo se completaba con otro, que permitía la conexión a teclado, a casete de audio, leds de 7 segmentos, interface RS-232 y terminales de teletipo.
