I was just telling my companion the other night that my new hobby (unintentionally -- it just started happening), is taking some of my favorite book's covers and adjusting their colors to my liking.
What does all this have to do with drum machines? Nothing really. I just thought the new colors of this book looked nice with the colors of this drum machine. Sort of a pumpkin blend. Which is exactly what is going to be happening tonight with some ice cream (don't ask!).
The Eko ComputeRhythm was the first programmable drum machine. There were punch cards that stored different drum patterns. Make sure to keep watching until around 2:40 to see this displayed. Quite impressive!
