No, I don’t have any tech from the 70’s there wasn’t much personal tech to speak of back then just a TV, radio, Variety of devices to play music, a calculator, and maybe a digital watch.

Yeah, that laptop did not have a hard drive. One of the floppy disks held the operating system and other held the program that you were running. 
 

I’m not sure they called that device a laptop back then might’ve been called a portable computer, but I could be wrong. 
 

I did not answer the question because I did not know what you meant between computational and physical elements. Are used to build and sell personal computers back in the early 90s.

@Troy computational elements means programs/code, physical elements means battery/power source/resistors/capacitors/cords/circuit boards and more

I answered Yes. I even have training on how to build a PC as recently as 2017.
