Civ1 had a bunch of bizarre bugs. Three that come to mind that my brother inexplicably exploited in some sort of rock garden tending experiment:
1) Reactivating a settler gave it all its action points back, so you could do any tile improvement in a single turn.
2) If you did this on a transport ship, you could railroad the ocean for the railroad trade bonus.
3) If you loaded a saved game, all units had the action points back, so you could run your units all over the world in a single turn.
Click all the settlers to farm/railroad/whatever a tile, then reload and have them do it to the next tile over. He railroaded the entire world including oceans on turn 1 via hut pops. The game took him weeks of reloading. Whatever floats your boat I guess.
