Starting the system

Follow these instructions to start the system:

  1. Start RK05 drive 0 (push LOAD switch to RUN position)
  2. Switch PDP-11/20 power on (click right of power switch)
  3. Load Address from switch register (click LOAD ADDR)
  4. Set switch register to 177406 (click above/below switches)
  5. Enable processor operation (click ENABLE/HALT)

Configuration

This system is equipped with the following devices:

  • KA11 processor with KY11-A operator console
  • 28KW MM11-E core memory
  • M792-YB Bootstrap Loader
  • KW11-L Line Time Clock
  • DL11 Asynchronous Serial Line Interface with default adress and vector (0177560/060)
  • RK11-D Disk Controller with default address and vector (0777400/0220) to which two RK05 drives are attached. The typical spin-up time for this drive is around 30 seconds, but is kept to a user-friendly 10 seconds in this simulator. Drive 0 contains a bootable image with DOS/BATCH, drive 1 is loaded with a scratch disk.

Using DOS/BATCH

This text shows the basic use of the DOS/BATCH keyboard monitor. After the system has been booted DOS/BATCH asks for the date and time, and whether you want to enter dialogue mode. In this mode the monitor asks some questions about the system's configuration. ALL INPUT MUST BE IN UPPER CASE. The date must be in the range 71-99.

To exit back to the keyboard monitor, type ^C and then kill PIP: 

  #^C
  .KILL PIP

Text can be edited with the EDIT utility. For example, to edit a file called HELLO.TXT: 

  $RUN EDIT
  EDIT  V08-01A
  #DK0:HELLO.TXT
  *I
  This text is typed on a PDP-11/20 running DOS/BATCH!
  ^J

  *EX
  #
To exit back to the keyboard monitor, type ^C and then kill EDIT: 

  #^C
  .KILL EDIT
  $
You can now print the contents of the file to the keyboard with PIP: 

  $RUN PIP
  PIP V10-03A
  #KB:<HELLO.TXT

  This text is typed on a PDP-11/20 running DOS/BATCH!

  #^C
  .KILL PIP
