+FOREWORD
+.sp
+.pp
+This manual is intended as a guide for three different levels of
+MP/M users.  Section 1 contains all the information required to
+enable a person to operate applications programs running under the
+MP/M Operating System.  Thus, the first section of this manual
+should enable the casual user to operate the system with a minimum
+amount of study and training.
+.pp
+The second section of this manual describes the MP/M system
+organization including the structure of memory and system call
+functions.  The intention is to provide the
+necessary information required to write page relocatable programs and
+resident system processes which operate under MP/M, and which use
+the real-time multi-tasking, peripheral and disk I/O facilities of
+the system.
+.pp
+The last section provides the information needed to tailor MP/M
+to another computer system.  In particular, the hardware dependent
+basic and extended I/O system entry points are
+described.
+Preparation of the MP/M loader using a CP/M 2.0 BIOS is also
+covered.
+.pp
+The system generation procedure is also described in the last
+section.  This procedure is of interest to all three levels of
+MP/M users because it describes how to configure MP/M for a particular
+applications environment.  This configuration includes the specificaion
+of memory segmentation, number of consoles, and selection optional
+resident system processes such as the printer spooler.
