Look! A Vectrex with 5 games.

The Vectrex, the only non-portable console to ever sport a built-in monitor, is both a piece of hardware that's worth collecting and a great console to enjoy vector games on. You can still find out more about it here and see just how innovative the thing was and how many people still care.
