Not a drum machine.  Core memory, all solid state -- one of the first, and as far as I know the first commercial product with interrupts standard.  Electrologica X1, from 1958.  Also its successor the X8, around 1964.  The X8 had a drum as a peripheral device, used in the THE operating system for paging virtual memory (512 k words).
