The nostalgia this post hinges on is amazing. I remember every one of the example pieces they show here. And what's amazing is many of them you'll find showing up in LEGO sets today. It's pretty rare LEGO makes single-use pieces, even really obscure pieces end up showing up randomly elsewhere.

Same! Thanks OP for the trip down the memory lane. I even remember which sets I got them from, for instance the yellow one with the "sonar" I got from this submarine: https://lego.brickinstructions.com/en/lego_instructions/set/... and the grey "consolidated interface" one with this jet: https://lego.brickinstructions.com/en/lego_instructions/set/...
