.... now please go back to minix.
Small memory footprint (kernel is 600 kB; full OS is 25 MB). If you have a very old laptop with a comfortable keyboard, then minix is a good alternative to use the laptop for example as a typewriter (and much more than that). And I find slip for connecting the old laptop to other computers, for example running OpenBSD, to make file transfer, also because of its simplicity, the right protocol. Secure connections are not always everything. I would not underestimate minix only because it has not the same goals or quality standards than OpenBSD. Rodrigo.
