This machine is ready to boot XXDP+ Diagnostics ("BOOT RL0") and run diagnostics (e.g., "R EKBEE1"):

• EKBAD0: 11/70 CPU DIAGNOSTIC (PART 1)
• EKBBF0: 11/70 CPU DIAGNOSTIC (PART 2)
• EKBEE1: 11/70 MEMORY MANAGEMENT DIAGNOSTIC

Step-by-step instructions are included below. Other interesting things to know about this machine:

• It includes an M9312 ROM at address 165000. The exact ROM is 23-616F1.

{% include machine.html id="test1170" %}

Step 1: We need to select a drive to load the XXDP+ Diagnostics disk, and since it is an RL02K disk, we need to use an RL02 drive. A typical PDP-11 machine with a single RL11 disk controller could contain up to four such drives, which we refer to as RL0 through RL3.

To select drive RL0, press {% include machine-command.html type='button' label='Select RL0' machine='test1170' component='RL11' command='selectDrive' value='RL0' %}
