Huh, looks like distrib/notes/i386/hardware on current and -10 has: | runs on all i486 or later PC-compatible systems with 1 to 32 processors. | The minimal configuration for a full, standard installation is 64MB of RAM | and 2GB of disk space. Do you have that 250MB from somewhere else?
It's from here: https://cdn.netbsd.org/pub/NetBSD/NetBSD-9.3/i386/INSTALL.html NetBSD/i386 System Requirements and Supported DevicesNetBSD 9.3 runs on all i486 or later PC-compatible systems with 1 to 32 processors. The minimal configuration for a full, standard installation is 32MB of RAM and 250MB of disk space.
It may be worth adjusting to note that a base-only could be installed in 32MB of RAM and 250MB of disk space, but would not be performant :-p
Considering how well NetBSD 10 runs on my Mac LC III+ with 36 megs of memory and on my VAXstation 4000/30 (also known as VLC) with 24 megs, I think 32 megs on even a slow clocked i486 should be pretty decent ;)
