I just wanted to chip in on this, as I certainly remember an older version of OT for the Apple II series.  I would have played it sometime in the years 1983-6; probably at the earlier end of that range.  The graphics were monochrome, and hunting was very different and quite difficult for me to get the hang of.  It was a sort of first-person shooter game, with your (stationary) hunting blind at the bottom of the screen.  At varying intervals, a game animal would come trotting horizontally across the screenalmost like a phantom, you remember those early graphics?and you'd hit the fire button to release a cloud of very slow-moving buckshot.  If they intersected just right, you got the kill.  This rarely worked for me; I remember being delighted when I saw the newer version in middle school.  I've never been able to find a downloadable version.  

Also, the earliest versions of OT seem to have been text-only games for TTY and, later, glass TTY.  Those were the ones when you hunted by typing BANG in a specified window of time.
