The minimal configuration requires 8M of RAM and ~60M of disk space.
To install the entire system requires much more disk space, and to run
X or compile the system, more RAM is recommended. (NetBSD with 8M of
RAM feels like Ultrix with 8M of RAM.) Note that until you have
RAM feels like Ultrix with 8M of RAM.) Note that until you have
around 16M of RAM, getting more RAM is more important than getting a
faster CPU.
