I have many of these kts. The first one I got was the 65in1, followed by the 150on1 and so on.
In Belgium where I live, the only store who sold these was Tandy aka Radio Shack.
It was the start of a fascinating hobby and profession.
The circuits are well explained in the context of young brains :D
These old kits even used Germanium transistors .
The 130in1 kit and the 200in1 that you show here was one of the follow up range.
I really love these kits and often build circuits with them
I will try to make a few contributions here in this forum.
