I played it at Eurogamer, and thought it would be interesting to have as a DYK.

It's basically just a Piano modded to play the original Doom, using the keys to play.

Some links.

So, is this an acceptable piece of trivia?

Well, there was something about the original doom being played on graphing calculators so I don't see why not.
