NAME

     uda -- UNIBUS MSCP disk controller driver


SYNOPSIS

     uda0 at uba? csr 0172150
     uda1 at uba? csr 0160334
     mscpbus* at uda?


DESCRIPTION

     The uda driver is for UNIBUS disk controllers that use MSCP.  Among these
     controllers are:

           DEC UDA50 UNIBUS ctlr
           DEC KDA50 Q22 bus ctlr
           DEC RQDX3 Q22 bus ctlr

     The uda communicates with the host through a packet protocol known as the
     Mass Storage Control Protocol (MSCP).  Consult the file <mscp/mscp.h> for
     a detailed description of this protocol.
