The Dreamcast is pretty welldefined when it comes to its system
memory:

SEGA Dreamcast
total memory = 16384 KB
avail memory = 13648 KB
using 230 buffers containing 920 KB of memory

I assume that it's possible to add more RAM if you feel secure
with a soldering iron (and perhaps even that isn't required), but
almost every single Dreamcast in the world will have the same
amount of memory as mine.  Also, there's no way to add a harddisk
without doing some soldering, so most people will either just
have a small bootloader on CD, or perhaps the root-filesystem or
such, but will do all swapping etc. onto a NFS-mounted
filesystem.  Not the best thing to do performance-wise, but
that's the only way to use NetBSD/Dreamcast unless you want to
modify it somehow.
