Early Birds of Orion Prototype Found

News

While going through some old cassette tapes I found the source code and compiled assembly of an earlier version of the Birds of Orion game that came on the 'B' side of my Meteor Swarm game.
It seems quite a different game, than what I ended up publishing, but one that I had completely forgotten about!
