[Coco] Simon Jonassen's Tandy Assembly demo

[Sean]

I'm displaying the CoCo3 at the Midwest Gaming Classic this weekend in
Milwaukee,  and I just remembered Simon's demo with the fire and spinning
cube video with music.  Is it available anywhere as a .dsk image?

archive has 3 files listed with his name, but aren't descriptive as to if
they are the one.
