> I am a little surprised though that nobody's written an operating system like this for standard hardware You can run a bare metal Smalltalk-80 or Squeak on the Raspberry Pi. https://github.com/michaelengel/crosstalk https://github.com/pablomarx/RaspberrySqueak I think Pharo uses the Squeak VM so it could conceivably run on the bare metal Pi as well.

The Raspberry Pi 1 is still a great device to experiment with alternative operating systems, most of which are far less resource hungry than Linux: - Plan 9 (http://9p.io/sources/contrib/miller/) - Inferno (http://lynxline.com/projects/labs-portintg-inferno-os-to-ras...) - RISC OS (https://www.riscosopen.org/content/downloads/raspberry-pi) - NetBSD (https://wiki.netbsd.org/ports/evbarm/raspberry_pi/) - FreeBSD (https://wiki.freebsd.org/arm/Raspberry%20Pi) - Interim Lisp OS (http://interim-os.com - this runs on Raspi 2 only, so porting to the ARM v6 in the Raspi 1 would be a nice project) - btw., this is a project by Lukas Hartmann, who is also the creator of the open MNT Reform ARM laptop (https://mntre.com) - (shameless plug) my bare metal "crosstalk" Smalltalk-80 (https://github.com/michaelengel/crosstalk) I'm pretty sure this list isn'

t complete... Some operating systems are not supported at the moment: - OpenBSD only seems to support the Aarch64-based models 3 and 4 - Haiku seems to be looking for a maintainer for the Raspberry port
