Hello!

Inspired by the latest newsletter, I decided to update my PiDP-10, answering Yes to all questions.  (Why not have the source, as well?)   All went well, but when I now reboot my RPi-4 PiDP-10, I get no blinkenlights.  Logging in via ssh, I receive the following before the prompt line appears:
  Starting pdpcontrol...
  Starting PiDP-10 with boot option 0000
  screen -dmS pidp10 ./pidp10 /opt/pidp10/systems/hills-blinky/boot.pidp
  0
 
I did not get this before the update, either.  Can anyone give me a clue as to what went wrong?

Thank you!

That is worrying. It's too late at night here to test it out now, but I will look into it tomorrow.

If you have the time and the inclination, would you mind trying:

pdpcontrol stop

then,

pdpcontrol start

...do things work then?

But I will check tomorrow!

Kind regards,

Oscar.

Oscar, 

I tried that, and even more: I moved the /opt/pido10 directory and did a complete install, but with no joy. I them moved my year-old directory back and have blinkenlights back again.
