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

Something like

might do the trick.

You might do a search for [sound effects generator IC]. I
think I still have a SN76488 that can be hooked up to a few
parts to generate many different kinds of sounds. They are
getting very hard to find, however.

But there have been other generator chips.

Reminded me of a old HEATH radio I built for my parents in about
1978'ish, sure miss those kids, BTW that radio is still working
and sitting on GrandMa's night stand, don't remember if it's keeping
time or not!

Anyone know if there are any of the older Heath kits around, not for
collecting, have seen some of those, but for building!
