Mass Storage Control Protocol

The Mass Storage Control Protocol (MSCP) is a protocol that was designed by Digital Equipment Corporation of Maynard, Massachusetts for the purposes of controlling their high-end mass storage options. First implemented in the HSC50 hierarchical storage controller, the protocol quickly spread throughout the entire line of mass storage controllers built by DEC. The UDA50 is an implementation of MSCP built on a Unibus card; other implementations (for example, the RQDX) stretch down to the Q-bus and small, 5 megabyte disk drives and even diskettes.
