Ah yes, I have a stack of these; lovely things for kids to learn some basic stuff. They are the oldest systems I own and they still work (they are fairly easy to fix).

Amazing! I don’t think I’ve heard of anyone owning many..!

1) Are any of them for sale? :)

2) Would you be open to recording a clean sound of one of its relays turning on and off? And helping me figure out some specifics about the motor wheel (its speed and whether it experiences any speed up)

Thank you! My email is:
