I am looking for a piece of hobby electronics I had in 1978 and this seemed to be a good place to ask. It was a black box with four or five toggle switches on the side. When the switches were thrown the box would make various chirping, squeaking, and siren sounds. I got it at a raffle in first grade (1978) in Berthoud, Colorado, but it seems it was a hobby project and so probably came from a hobby magazine from that time. Does anyone have any old copies of magazines from that time? I am looking for the schematics so I can rebuild it. Also give me names of the various magazines that I might search, or any other ideas to find this schematic would be greatly appreciated.
thank you for your time rK
