I just added my avatar to my profile, and, as with other forums, I know people will be asking me about it.
Without getting into great detail, I love tinkering with old radios and old cars. I love collecting old recordings including old time radio. By trade I run a business related to old car radios. Some years ago I picked up a literal trunkload of junk manual radios from 55, 56, and 57 Chevys. The photo is of these junk radios in the back of my 64 Thunderbird. Since the photo was taken almost all of these have been parted out. While not directly related to playing music from a laptop, in the big picture there's a relation.
