That 40kpx x 40kpx scan (800 Megabyte) of that map broke my system. Wow.

I just downloaded and thought maybe 80MB... why is it taking so long... hm

Edit: Made a 30MB png with linear interpolation (because I don't have all day): http://move.rupy.se/file/turgot.png

Here's another map of Paris (this time with interpolation): http://move.rupy.se/file/eau_paris_3.png
