I got my C64 @1985. I got it from some guy selling it in the local newspaper for $200. I would later get the disk drive for a little bit more, from a mail order service. It was my go to gaming system until @1989, when I got an Amiga 500 and the NES.
I checked out this cool video on the making of the machine on YouTube.
