OK Lego experts - what do I have?

I just grab whatever LEGO bits I find when at the Goodwill Outlet, making sure not to get any of the pale imitations. Years ago a box of this stuff got me a nice MacBook with an SSD in trade; I don’t know why I keep buying it, but when buying by the pound it seems pretty affordable. Maybe I just need to sit down and play with this stuff and try to bring back memories of the’70s.

As I clean out the basement and consolidate I’ll probably have more; I think I’ve got more of the robotic bits and pieces somewhere, but I just haven’t stumbled upon them yet. So much fancy stuff by comparison - I would have killed for these parts 40+ years ago...
