Thanks guys,

I didn't know about these early Stern games, just checked them all out on the IPDB.  What do people know about this early incarnation of Stern (1977-1984). Is it related to the present company?  Seems like the artwork on most of these games is very good, the playfield, backglass and cabinet of each machine seems to present a coherent whole unlike some of the games from other companies of this era.  The level of innovation seems to be up there too, like that ball lock maze on Flight 2000 or the upper flipper in Hot Hand, not to mention the whole concept of Orbitor 1!
