Help identifying vintage escrap cards and boards

I've got some really interesting pieces here that I'm sorting out of a lot from an electronics hoarder. This guy had everything from electrical test equipment, computers, arcade games, early printers, etc. I truly am looking online and not finding anything like these. I put an SD card in some of the pics for size reference. Any and all help appreciated!!

That first board looks like something for you to build your own board. It is laid out so you can solder components and wires to whatever you want.

I agree, and I have several different sizes and shapes all made by Radio Shack. I found something called schmartboards that look like modern versions, but I had never seen anything like this before. Was this common in the 70'swith Radio Shack? Any idea on their value? Thanks for your input!

Radio Shack once sold all sorts of kits, as did Heathkit. All types of electronics type kits. I had a little metal detector from Radio Shack in the mid 60s. By the 70s they had the little Tandy Radio Shack (TRS) computer beginnings
If you've ever seen old comic book or old magazine advertisements, they used to be highly concentrated near the back, advertising more stuff than I can recall. My interest was mostly stamps and coins and they'd advertise them as an assortment. They'd have little photographs of all the better stuff in the package, maybe you'd get one in the lot, plus a bunch of other crapola
Radio shacks ads were of transistor boards, and their photographs were much the same, showing oodles of boards filled with transistors and stuff. Kinda like little grab bags full of stuff. Guys from school would by them and talk about how they fixed a TV or radio etc with a particular transistor they found on one of the boards or something like that

They all came from the same location, but it was a mix of items there together. I DO however have several boards that say Univac and are in pretty good shape. They are not pictured, but I can add them later if needed. I have a few local buyers interested in some of these items, but I do not trust them completely to offer fair prices. I would like to sell these, and appreciate all help with identifying them as well as any input on value. Feel free to PM as well. THANKS!!

I'm in a rush right now and can't ID everything, but I know the things with the U-shaped handles on the top are logic modules from an old computer like a Burroughs 5000 or Univac. They're an example of "cordwood" modular design: "Normal components were soldered in parallel as closely as possible between two or more circuit cards. The benefit of this approach was high component density, an early attempt at miniaturisation. This technology lived on into the early transistor era of the 1960's, and NASA considered it for use in the Apollo Guidance Computer."

Some of the other cards might be from the same system. Did some of these items come from the same source?

I'll try to ID more later today when I have some time. Have a meeting I have to attend now.
