newly assembled PiDP-10 behaves as "headless": no blinky lights

[Harry Saal]

I finished assempling my pido10. I can run the pidp10-test program, and see all the lights and every switch is detected on and off. But when I boot (or pdpcontrol start 0) i do not get any blinking lights, etc. 

I know that simh is working, since I was able to pdpcontrol start 0200 and start TOPS-20 and run it successfully...via SSH to my raspi4.

pdpcontrol start 0 returns 0, which seems right.

I am running Ubuntu 24.04 64-bit and didn't expect issues, esp. since the test program sees the front panel LEDs and switches. But not when I am running one of the OSs.

Suggestions?

[Harry Saal]

A possible clue? I reinstalled from scratch, cloning from github. I noticed that duing the install it executes raspi-config for i2c and vnc, which fail!. But raspi-config doesn't exist for Ubuntu. So do I really have to switch to raspi as my linuc OS?

[Harry Saal]

Seems raspi OS is reqjired. Why the install.sh doesn't verify this......?? 

Lights now run!

If am running the Raspberry PI, and don't get blinky lights automatically.  I have to run the test program directly through the terminal.  In fact, I get no automatic reading of the switches.  Setting them through pdpcontrol start accomplishes nothing, I cannot load TOPS-10, or ITS.   However, the test program I run directly shows every switch working fine, and using ssh connections does not improve the situation.

I read this message to see if I could make some progress with my situation, but there have been no answers.
