There is a FreeBSD for Raspberry Pi distribution. It might be an even better stylistic match to the PDP-8 emulation we're doing here than Raspbian Lite.

I do not suggest moving the binary OS images to it — at least, not without trying it first — but it would be nice to see it run that way.

Some more thinking on this brings up several things that are likely to need adjustment:

  • Does /dev/gpiomem exist, and does adding the user to group gpio give access to it?
  • Does setcap exist, and does our call to it allow the installed program to raise its thread priority?
  • All the systemctl commands will have to be replaced with direct calls to /opt/pidp8i/etc/rc.pidp8i
  • What does it take to integrate the script into the /etc/rc.conf or /usr/local/etc/rc.conf system so we can say pidp8i_enable=YES to get it to boot on startup?
