If you have nostalgia for phosphor, but don't want a huge, hot, CRT in your office, and you have Mac, check out the terminal emulator "Cathode": http://www.secretgeometry.com/apps/cathode/

(No association. I just like the product.) It's extremely configurable, you can simulate a wide variety of tubes in various states of (dis)repair.

Probably the perfect way to play nethack.
