The MPC2000, MPC2000xl, and MPC3000 each update their Operating System (OS) by reading it from floppy disk. The MPC3000 and
MPC2000xl read the OS once, then it stays in the sampler for good. The MPC2000 must boot up from a floppy disk every time you turn it on.
The OS versions here are the latest ones released by Akai.
