I was just finishing up a banana split at the local DQ in a commercial strip mall in the 70's. As I enjoyed the summer's treat, I saw a window filled with the most exquisite technology I had ever seen. Radio's (of course), special cords, weird "Odyssey" pong gaming consoles, betamax players, and so much technical sundrie I couldn't decipher at my age; but I knew I was hooked.
My banana split and I snuck in and walked the aisles in wonderment. Everything was so bright and "modern" and at your finger tips. From batteries to color tv! I must have spent an hour in there just looking at stuff trying to determine their use.
