In my earlier "Re-visiting my PiDP-11 build" post I mentioned starting with a blank slate (actually, SD card) with the newest Raspberry Pi OS and a fresh install of Oscar's PiDP-11 using
Option #2 from the "pidp-11-building-instructions" document.
I mentioned there that I was having even worse behavior with the rotary switches than with the original beta software. Back then, the only issue was the LEDs cycling in the reverse direction from the knob rotation. With the newest software, rotating the knob via a single detent will advance the LED 0, 1, or 2 positions in a random direction. At that point I asked if perhaps one of the fixes wasn't merged to the current install kit.
Today I came downstairs to my office and found the front panel completely off. I had been running RSTS/E DISPLY on the "console", so I don't have a clean error message. But there's enough there to show that indeed, the console process died:
RSTS V10.1-L RSTS/E V10.1 Status on 29-Apr-24 02:00 PM Up: 18:08:33
100.0%User, .0%I/O, .0%Exec, .0%Idle, .0%Lost
istorybuffer_idx2pos: Assertion `idx < _this->endpos'
failed.eslocalhost: RPC: Unable to SR = Connection refused (in .//../../../07.0_blinkenlight_api/blinkenlight_ .5nt.c, line 296)
Which sure looks like one of the old-time bugs. My original beta software usually made it several months between console crashes.
I don't know if enough people are doing new installs and/or running their PiDP-11's 24/7 to have noticed this.
Can someone "in the know" take a look and let me know what I should try or do?
Hopefully it is something simple like "just recompile everything - the binaries are out of date", but I don't want to get further away from a known state before getting expert advice.
