Boisy, I have the program on a disk here, including a few wireframe models for
it. I will dig it out and send you a copy. It is actually two programs, one for
entering 3D wireframe coordinates (very tedious, but it worked) and one that
did the calculations and rotation. You'd enter start and end positions and
number of steps, then it would pre-calculate the movements before displaying
it. ISTR it would take several minutes of calculation to get a few seconds of a
simple object. The Space Shuttle wireframe took significantly longer.

I could swear I saw an ML routine in one of Barden's books that could use the
same type of wireframe data. I intended to try it but can't remember which book
it was in... either Assembly Language Programming or Color Computer Graphics.

Another 3D CoCo1 game nobody has mentioned yet... the name eludes me but it was
like Breakout, but facing the wall with the ball moving toward and away from
you. I think it was 3D Brickaway.
