Throw Another Analog On The Fire
Here's a promotional flexidisc for the EML line of synthesizers. Surprisingly, there is no commentary or sales pitch on the double-sided disc - just bleeps, bloops, and drones. Since the company ceased making instruments in 1976, this obviously predates that somewhat. I remember playing it a lot as a kid - I desperately wanted a patchable synth (PAIA, preferably).
