Answer 1

Define "electronic"! "Electronic Gadgets" were not around until the early 70's. Before this there were "electrical" devices. All were anything but portable. They were the transistor radio - that's it. Some other early devices were the TV, radio (valve), vacuum cleaner, refrigerator, Geiger counter, and a few others. By 77 there were some calculators but these were few and very simple.
You should have a good idea of those available today.
