I think I remember Descent on VB

Back in 1995, I tried out a VB on an in-store display, and it was a spacecraft shoot-em-up. I distinctly remember shooting at the reactor, but not able to get out before the mine blew… Later that year, I bought an IBM Aptiva with Descent Trial preloaded…. what do I see, but the SAME REACTOR, and trying to get out of the mine before it exploded. But the VB was all red and black. I didn’t see Descent on the games list, so I’m wondering if I just dreamed all this, but it seems very real…
