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 <tt>/dev/gpiomem</tt> exist, and does adding the user to group <tt>gpio</tt> give access to it?

  *  Does <tt>setcap</tt> exist, and does our call to it allow the installed program to raise its thread priority?

  *  All the <tt>systemctl</tt> commands will have to be replaced with direct calls to <tt>/opt/pidp8i/etc/rc.pidp8i</tt>

  *  What does it take to integrate the script into the <tt>/etc/rc.conf</tt> or <tt>/usr/local/etc/rc.conf</tt> system so we can say <tt>pidp8i_enable=YES</tt> to get it to boot on startup?
