Just looked up "Armor Attack" because I just played it on my Vectrex.
Love the game. Sadly the Vectrex has a flaw in that it is very easy too make one (or even two) tanks move up and down all the time without being a threat to you....and simply shoot off the helicopters all the time...which makes it very boring if you do this

There are some developments in the Vectrex world where MAME could actually be run from a multi-cartridge which opens up the Vectrex to playing all arcade vector games !
