At least for NetBSD the install cd offers a selection of kernels and
TINY kernel has no problem booting in 8M. For my first install
however I took ram from another PC to give 20M then compiled a
minimal kernel before going back to 8M. This is a 486dx66 used as
firewall and I also have a 486dlc33 again with only 8M and both
NetBSD 1.6. Disk space used is 32M swap, 33M for / and 41M for /usr.

I don't think either of those systems would be useful for learning
about NetBSD. I'd go along with the sugestion other poster made to
grab an old version of FreeBSD from around same era as the hardware.
