Isn't it so awesome to recall memories like that? I wish I could go back to those times....now, my dad has passed and I'm basically estranged from my mom because of issues she and my wife had when we got together and got serious (a LONG story for another time)...life was so much better back then, that's for sure.
I remember when my folks bought me these toys when I was a kid; I had a finished basement in my childhood home in which I had my records, some bean bags, a disco ball with spotlights, these stereo consoles over the years...I even had six pinball machines my dad bought from a local arcade which was selling them. I always had my birthday parties down there, with friends and pizza...as I played my 45s that were big at the time (stuff like "Jesse's Girl" by Rick Springfield, "Abracadabra" by the Steve Miller Band, "Eye of the Tiger" by Survivor, "Kiss on my List" by Hall and Oates). Years later, the basement became my spot for my DJ equipment, until eventually my folks sold the house and moved west, while I got my own place and got involved with a girlfriend at the time (I wish I never would have sold off my Technics 1200s I DJ'ed with, that's for sure).
But, like you, I still have the 45s amassed from that childhood era -- in fact, we once had a water heater break on us, which caused a flood and fire in the basement, and my 45 collection was wrecked with water damage...however, I was able to salvage the records themselves, and even some sleeves survived! Others needed to be replaced by Radio Shack/Realistic 45RPM jacket replacements (remember THOSE?)...I STILL, to THIS day, have the 45s with the water damaged sleeves on some of them, plus the ones that were replaced with the Radio Shack jackets...
