Something most people don't mention is that if you were lucky enough to have three DOS machines side by side, and also have them networked (IPX or TCP/IP) you could run DOOM in 'ultrawide' mode by bringing up the game across all three monitors, with the -left and -right command line options on the respective machines. I'm not sure if any of the engine ports (zDoom etc.) still support this though.
