Amiga uses the DB-23 for monitor, I don't believe it's made anymore, however, it appears you can still order it. It's not as unusual yet as the DB-19.

(And now that you can order, for the first time, a new Amiga with an open source operating system, you don't need the DB-23 anymore, it uses HDMI. Vampire v4 stand alone. No affiliation, just fascinated.)
