Sony CP/M machine?

The machine has 3.5" single-sided floppy disks, both black & white and RGB video outputs, an RS-232 interface, parallel interface, and a DB-25 connector labeled "external drives". It also has a "supercharger" unit with it that contains an 8086 processor. This "brick" plugs into the back of the SMC-70 using a centronics-type 50 pin cable. According ot the documentation, when this "supercharger" is plugged in, the Z-80 processor in the main unit handles all of the I/O functions and the 8086 becomes the default CPU. The system uses either CP/M (in Z-80 mode) or CM/M-86 (in 8086 mode). I have manuals and documentation for the machine, the Sony applications, and the CP/M and CP/M-86 operating systems, but the original system and applications diskettes were not passed along to the person I got the machine from by its original owner. Anybody have any idea where I could get at least the OS for this thing? It looks like a neat little machine. Kenneth L.
