The computer game device null which consists of the sound source tip/chip which builds in the plural sound source output sections

摘要

PURPOSE:To provide a sound source tip which elinimates a complicated circuit structure, decreases the number of parts to be mounted and is easy to use. CONSTITUTION:A plurality of sound source output parts of PSG and ADPCM as various kinds of sound sources and a mixer circuit to mix respective sound source outputs are combined together to form a single tip. In this instance, an inner resistor to receive a control from a central processor unit is provided in the same tip, and therefore, it is also possible to arrange resistors of the respective sound sources all together.
