Notes on oskit: XXDP V2.2 and V2.5 system on RL02 volumes

General remarks

See notes in w11a_os_guide.md on

  1. I/O emulation setup
  2. FPGA Board setup
  3. Rlink and Backend Server setup
  4. SimH simulator setup
  5. Legal terms

Also read README_license.md !!

Installation

A disk images for XXDP V2.2 and V2.5 are available from bitsavers
http://bitsavers.trailing-edge.com/bits/DEC/pdp11/discimages/rl02

         xxdp22.rl02.gz
         xxdp25.rl02.gz

Download, unpack and copy the disk images (*.dsk), e.g.

       cd $RETROBASE/tools/oskit/xxdp_rl

       disk_path=http://bitsavers.trailing-edge.com/bits/DEC/pdp11/discimages
       wget $disk_path/rl02/xxdp22.rl02.gz
       wget $disk_path/rl02/xxdp25.rl02.gz

       gunzip -c xxdp22.rl02.gz > xxdp22.dsk
       gunzip -c xxdp25.rl02.gz > xxdp25.dsk

Usage

  • Start disk imge in SimH simulator (see section SimH in w11a_os_guide)

         pdp11 xxdp22_rl_boot.scmd
     pdp11 xxdp25_rl_boot.scmd

    or on w11a (see section Rlink in w11a_os_guide)

         ti_w11 <opt> @xxdp22_rl_boot.tcl
     ti_w11 <opt> @xxdp25_rl_boot.tcl

    where <opt> is the proper option set for the board.

  • Hit <ENTER> in the xterm window to connect to SimH or backend server. The boot dialog in the console xterm window will look like (required input is in {..}, with {<CR>} denoting a carriage return.

       XXDP V2.2 boot dialog:

     CHMDLD0 XXDP+ DL MONITOR
     BOOTED VIA UNIT 0
     28K UNIBUS SYSTEM

     ENTER DATE (DD-MMM-YY): {10-jan-85}

     RESTART ADDR: 152010
     THIS IS XXDP+.  TYPE "H" OR "H/L" FOR HELP.

     .

    XXDP V2.5 boot dialog:

         BOOTING UP XXDP-XM EXTENDED MONITOR

     XXDP-XM EXTENDED MONITOR - XXDP V2.5
     REVISION: F0
     BOOTED FROM DL0
     124KW OF MEMORY
     UNIBUS SYSTEM

     RESTART ADDRESS: 152000
     TYPE "H" FOR HELP !

     .

   Now you are at the XXDP prompt '.' and can exercise the system:

     . {H}
       --> will print help
     . {D}
       --> will list the files
     . {R EKBAD0}
       --> will run the 'PDP 11/70 cpu diagnostic part 1'

    There is no halt or shutdown command, just terminate the simulator or backend server session.
