All the maps I have seen so far on Doom as of this writing, have been 
 screen grabs for episode 1, and are very difficult read. So I first 
 endeavered to screen grab maps for episodes 2 and 3, cleaned them all
 up and added my own codes for different items like risers, switches,
 secret doors, etc.; as well as bullits, shells, etc. for Episode 1. I used
 Corel Draw 3's "Photo-Paint" in 256 color mode, and through a process of
 elimination, using a Citizen GSX-140plus color dot-matrix printer, I came
 up with color-coded maps for all three episodes. 
     While my episode 1 maps include a matching map with item codes like
 bullits, keys, rad suits, etc. and their location; episode 2 and 3 do not;
 due to fact that recently I have found that it is much more fun to randomize
 items, especially in modem play. 
     I've included my master key called MSTRCODR.BMP, as well as a text 
 on the color scheme called DMCOLOR.TXT, if you want to try to put in your 
 own items or customize your own maps. Also included is CLCODE1.BMP, codes
 for all items that you could come across in DOOM;( I combined both med-kits
 and stim-packs as one symbol - a red cross - due to that they only differ 
 from the amount of health points you get) ; and CLCODE2.BMP which is
 used for my standard maps, that don't include special items like bullits,
 keys, med-kits. 

     Suggestions:

  -- Because of the variance in print and color quality among color printers,
     you may want to print one up first on your own printer, then compare 
     it with the screen image. What you see on the screen, is not what you
     get on the printed page, especially in shading, texture, and color
     hue and saturation. You may have to experiment with it until you get
     something that is satisfactory to you.

  -- If using a b/w printer, you may want to use a paint program to erase 
     such things as steps or colored items if they seem to confuse you
     in b/w mode.

  -- Sometimes my printer would glitch somewhere during the printing process.
     If this happens to you, it may not mean that the map is bad.
     Check your ribbon to see if you have a fold-over or that it is loose.
     Sometimes it could be an electronic glitch between computer and printer.
     On an average for me, it was a one in ten ratio. 
     If it continues at the same place, it could be a corrupt map. However,
     I have checked and printed each and every map at least three times with 
     no problems with the maps themselves.

  -- Look for DMMPCC1.ZIP and DMMPCC2.ZIP, my color-coded maps for DOOM's  
     Episodes 1 and 2, respectively.
     Also look for in the near future color coded maps for the more popular
     DOOM Wad add-on such as starwars, arena, etc.
