Now you've got me wondering if my parents still have their encyclopedia set. I need to show it to my kids!
My cousin, who's probably 10, was fascinated by my parents' old World Book set (I think it was from '82-ish) when they visited at Thanksgiving. So much so that she asked my mom if she could have them; guess who got to tote that 50+ pounds of books into the post office to mail them?

Why she couldn't have asked for them when they were still in town is beyond me.
I remember getting our first microwave, back when we lived in CA (we moved here when I was 5, more than 30 years ago) It was MASSIVE. It was so big that I remember my mom using it for a hiding place for stuff if a last-minute house showing came up and she needed somewhere quick to stash magazines, etc.
We got our first video camera when I was 10--it was one of the ones that had 2 separate components, one of which was a huge chunk of the VCR itself (and they were metal back then, not plastic, so they weighed a TON.) The camera was connected to the part that held the tape by a long cable and kinda looked like a police radar gun; the whole ensemble was very heavy and big and awkward to carry. Years later, we were watching some family vacation videos from WDW and noticed a lot of footage of wildlife in the parks (ducks, etc.) I had never realized that my dad was such a nature lover, and when I asked him about it, he looked somewhat ashamed and admitted that what he'd actually been trying to do was run down the battery a little faster so he could stash the whole shootin' match in a locker in the park and not have to lug it around anymore.
I
totally remember waiting by the radio for my favorite songs to come on. The one I have the most vivid memory of is "Pour Some Sugar on Me" by Def Leppard--my tape recorder sat by the stereo for DAYS until I was able to capture the whole song.
Oh, and big Friday nights were spent at the roller rink, hoping that you'd get asked to skate with someone during the "boys ask girls" skates. Songs I distinctly remember hearing while there include "Centerfold" by the J. Geils Band and "867-5309" by Tommy Tutone.
