How to Start the PDP-11/03L

1. Make sure the HALT switch is in the DOWN position (CPU Halted).
2. Apply power to the peripheral devices and allow sufficient "warm-up" time for the CRT Display.
3. Apple power to the central processing unit.
4. Move the HALT switch to the UP position (CPU Enabled.)
5. Cycle the RESTART switch (the switch is spring loaded -- just briefly press it upwards.)
6. The console terminal should display the number 28 (this is the memory capacity detected in K-Words) and then the START? prompt on the next line.
7. The following start commands are accepted:
   
   • Y -- This boots from the default device (DY0:)
   • N -- This terminates the boot process and enters console ODT with the CPU Halted. For more information on ODT, consult the LSI-11 CPU Reference Manual.
   • DY0: -- This boots from drive 0 (the Default option.)
   • DY1: -- This boots from drive 1 (remember to mount a system disk in drive 1 -- this is normally only done if there is a failure of drive 0.)
8. If you selected anything other than (N), RT-11 should load and display the start message. If the boot process fails, the CPU will halt (the run light will go out) and enter console ODT mode. This usually means a hardware failure of the boot device or corruption of the system disk.
