Way back in about 1965 a friend, Francis Wood, and I made a record. As I recall it was me saying, "Mary had a little lamb". Very profound! We used the lid of an old coffee jar, a big horn and a needle. It involved shouting very loudly!
Whilst looking for something else, I came across it earlier today. Of course, these days I have nothing to play it as all my record decks went long ago. My son has a deck, so I could ask him sometime.
It was with Francis that we made some early experiments with optical communications. OC171s with paint scraped off. Memories.
