It's different if you're looking for in-game maps. Birdseye view in-game maps like the ones from the Super Nintendo version of Wolfenstein 3D and the Catacomb Trilogy (Consisting of Catacomb Abyss, Armageddon and Apocalypse) might be the style you seek. Mind you Corridor 7 does have in-game maps, but they are quite vague with only blue and grey colours, yellow dots to indicate enemy positions and red dots wherever the player places mines. Is this Catacomb you are talking about fully titled as "Catacomb 3-D: The Descent"?
