Nothing happens on the ssh console anymore; the real work is happening on the backplane and its effect can be seen on the terminal connected to ttyS2 (uart) on the Unibone:

Running xxdp tests
Once the above image has started you have a lot of xxdp tests available. You can get a list by entering “D” plus enter on the command line. This shows all gazillion tests very slowly. To stop display use CTRL+S, to continue use CTRL+Q.
Let’s run a few tests.
Let’s start with VRLAC0.BIN, a diskless test for the RLV11 RLx controller. Use the command:
| Code Block |
|---|
.R VRLAC0.BIN |
This should trundle along for a while, and after that it shows:
...
This thing saying “DR” is called the “SUPERVISOR”, some tests start with that. In that case you have the following commands:
| Code Block |
|---|
STA/FLAGS: start test initially
RES/PASS: restart after ^C (back to pass 0)
CON/TESTS: continue where stopped after a ^C
PRO/FLAGS: proceed after a error halt
DRO/UNITS: drop unit from testing
ADD/UNITS: add unit for testing
PRI print all statistic tables accumulated
DIS/UNITS: the hardware P-tables are printed
FLA the current flag-settings are printed
ZFL all flags are cleared
The flags are:
HOE halt on error, causing command mode
LOE loop on error, causing diagnostic to loop
IER inhibit error reporting
IBE inhibit basic error reports
IXE inhibit extended error reports
PRI direct all messages to the line printer
PNT print number of test being executed
BOE bell on error
UAM run in unattended mode, bypass manual intervention
ISR inhibit statistical reports
IDU inhibit dropping of units by diagnostics |

A session of this test:

After a while this goes clearly south:

and after 20 seconds more the excrement really hits the rotary device:

Well, press CTRL+C to stop the test, and enter EXIT to exit the SUPERVISOR.
