> cars don't need to know where they're going. Each road tile type carries its own direction. Road tile 0x16 is the bottom part of a horizontal road, meaning that cars can only drive from left to right on these roads.

There's always a simple explanation for anything that looks too complicated for an old game to do.

This really takes me back. My first actual 'use' for Linux was making routers out of leftover computers.

The perfect machine back then was a 100MHz Pentium, in a slimline desktop case. At the time, the Pentium III was the current desktop chip, so you'd have a pile of early Pentium-class machines to use. And even a 10mb ISA network card (3Com if possible) would have plenty of power for the internet connections of the day. But 100mb PCI cards were still fairly cheap.

Install two NICs, load your favorite Linux distro, and then follow the IP-Masquerading HOWTO and you've got internet access for the whole apartment building, office, or LAN party.

Eventually I moved on to Linux Firewalls by Robert Ziegler for a base to build on.

After that I started piling other services on, like a spam filter, Squid cache, it was amazing to get so much use out of hardware that was going to just get thrown out.
