When a Charon-PAR instance is started, the first interface visible to the user is the PDC (processor dependent code) console of the emulated system (i.e., the firmware of the system). It provides some important function that will be described below:
PDC Main and Configuration Menus
At the console prompt Main menu: Enter command or menu > the user can enter either one of the available commands directly or display the main menu by entering menu:
Commands can be entered by typing the full command or the abbreviation indicated by the uppercase letters. The commands can be entered in lowercase or uppercase letters.

ODE MAPPER2 Program
The MAPPER2 program can be used to report all the emulated hardware of the emulated historic HP3000 or HP9000 system.
To start it, perform the following steps:
- Start the Charon instance.
- At the PDC menu, enter
BOOT PRIto boot from the main path. - At the prompt
Interact with IPL (Y or N)? >, enterY. - At the
ISL>prompt, enter the commandODE. - At the ODE> prompt, enter
RUN MAPPER2.
The program will display the hardware found on the system. A partial output is shown below:
After the program has completed, type exit at the ODE prompt to return to the ISL prompt, or type exit in the hppa console to stop the emulator.
