Yep. It's funny, but a 5 year old can easily manage an oscilloscope and basic analog circuits. And a 6-7 year old - an oscilloscope, a logic probe and digital circuits. The kid doesn't have to be a wunderkind too. It is just a matter of being exposed to these tools and having dad working at home with the equipment.
I'd spend an hour putting parts in, then I'd get to my favorite part where I got to use the soldering iron. I'd flip the board over and solder all the holes I'd just filled with parts. My dad would monitor me for a few minutes before he got bored and then it was all me.
I don't remember how long it took because it was so long ago, but I remember finally soldering the last part in and looking in awe at my bootleg Apple ][+. The first time I used it it didn't even have a case. And no disks either--we used the tape to load some games and play around. I learned basic that way and that computer is probably why I'm a programmer today.
I loved that computer—I still have that computer. And it still works.
