Nope Bill, but I do 'remember' my first X-in-1 kit I got as a kid.....can't remember who produced it, but having to personally insert the numerous connector strips into the underside of the breadboard section of the kit, as a 7 year old, was rather tedious.....and counter-productive when the kit was supposedly marketed as a 'ready to use' product.
Quite obviously manufactured in pre slave-labour times...
I had some of those kits back when I was a kid (mid 70's). My soldering was not so good back then, I think I melted more of the plastic than solder I remember soldering to the parts and they would melt through the plastic perf board.
