Had an Atari 2600; I don’t remember how many joysticks I wore out. The home versions of arcade games were crap (Pac Man, anyone?), and yet we found them immensely entertaining. These days, the games you can play on PCs far outweigh arcade games in terms of complexity and graphics.
Followed it up with a Commodore 64, including a dot-matrix printer, and a turtle-speedDatasette tape drive for storage, followed up by a gigantic (but “much quicker”) 1541 disk drive. You could fit a whole 170 KB on a disk! These days, I can hold a lightning-fast multi-terabyte hard drive in the palm of my hand.
I remember a toy where you’d squirt a blob of goop from a metal tube onto your fingers, said blob being composed of a significant quantity of organic solvent and some other materials; you’d roll it around for a bit to get it to firm up, then you’d stick a straw in it and blow it up to make giant bubbles; the solvent would evaporate as the bubble expanded, resulting in a slightly durable plaything. Just found it: Super Elastic Bubble Plastic!
My dad worked for a medical supply company, so our homemade go carts were fitted with high-quality hospital gurney wheels: metal, with a shock-absorbing band of grippy polyurethane around the rim, and ball bearings at the hub.
I remember some sort of natural gas supply problem in Erie, PA in the mid 1970’s (prior to '77); our family turned the heat way down in the house, shut off the heat altogether to the bedrooms, and we all slept together in sleeping bags in the family room for a while.
Rotary-dial telephones. By the 1980s you could get touch-tone service for an extra fee, but my parents preferred to save money. At one point we had push-button phones that could switch between touch-tone mode and pulse mode (emulating a rotary dial phone). You’d use pulse mode to call up a long-distance service, and then switch to touch-tone mode to enter your account number and the long distance number you wanted to call.
Pumping the accelerator pedal on your car to set the choke and get a couple of squirts of fuel down the carburetor throat before you turned the key to start it (and then lightly tapping the pedal again a little after the start to get it to come down off of high idle/choke).
