Whoa! You realize that almost all of these are somehow 
related to CCE/Brazil? For example most (all?) the Atari 
titles in this list have been programmed by CCE, 
according to Tempests prototype page. I wonder how 
Eckhard will interpret this :-)

Aha, almost the complete library. Anyway, we can exclude 
them as the origin, right? (Though I'm sure guys like 
Stephen Landrum or Dennis Caswell were able to discover 
this technique by themselves...)

Here comes Activision...

Maybe we should pass Tempest these lists to analyze them 
by date and origin :-)
