13. XXDP Notes for XXDP and XXDP V2 Operating Systems Pete Turnbull February 1993 XXDP Diagnostic Program Monitor XXDP is a small compact operating system designed to provide a suitable environment across the range of DIGITAL Q bus and Unibus machines to run diagnostic test and maintenance software The name comes from the four character names given to diagnostic programs XXDP is not intended to provide a software development environment this is usually done under for example RSX11 Early versions were quite simple and consisted of a monitor program such as RKDP SAV the monitor for RK05 based systems and a few utilities Later versions called XXDP added a few more operations and used monitors with names of the form HMddvp SYS HM signifies a monitor dd is the device mnemonic and v and p are the version and patch levels XXDP could tell what kind of bus system it was running on unless it was an 11 23 or 11 24 XXDP Version 1 1 sometimes called XXDP or XXDP Super plus was basically similar but with some enhancements notably the introduction of Diagnostic Runtime Services which provided a common supervisor and setup functions for compatible diagnostics XXDP Version 2 added memory management English type commands in addition to the single letter monitor commands and device drivers separate from the monitor program itself Naming Conventions XXDP where XX is a device mnemonic and DP stands for Diagnostic Program is
