Noise toy wiring help

[radioman24]

Hi, i ran across an old noise toy the other day in a radio box of parts,etc, anyways it is in a yellow box like a humble noise toy model 13 and it has 7 wires they are

red
black
white
blue
brown
green
yellow


i know red and black are power and ground, no idea what the other ones are though

any idea's??

i have a few chips but none matching the same white is normally audio
blue may be key up or mike gain the other three think would be for switches never seen a chip with so many wires though good luck i did see some other info here or on onther forum you may want to look around a bit 73

Is it one of the types of toys that lets you record your own sounds? Those have a few extra wires.
