The E-MU SP-12 (or SP-1200), a high-end sampling drum machine for rap music production. These pieces of equipment came out around 1985 and 87 respectively. The SP-12 did not have an internal disk drive, but EMU saw the problems since it only worked with a Commodore diskdrive. So they made the next model with an internal drive. Incidentally Ced-Gee of Ultra-Magnetics was the first person in hip-hop to use this machine which has become one of the most sought after pieces of equipment to date. So much that EMU has reissued the SP-1200. "Just me, a mic, and an SP-12" -- Young MC (Album Filler).
