Alright, I just remembered a game whose identity has been bothering me for a while.  I remember playing it as a kid in the very narrow entrance of an old school (or I guess era-appropriate) diner that was right down the street from where I grew up.  The basic premise was that you were trying to save a human family (father, mother, sister, brother...maybe) from a swarm of evil robots.  We're definitely talking early to mid-80s.  Not a bad game at all, but very basic graphics and whatnot.

Anyone have any ideas?
