Trying to remember the name of an old firing system

[displayfireworks1]

I was talking with someone about this firework firing system from the late 90’s and could not think of its name or even if it still around. I remember it was on display at one of the PGI conventions. Everyone was crowed around it. Apparently new and innovative at the time. Perhaps someone can remember its name.

What I remember was the slats were this bright yellow and looked like rain gutters. Every 6 inches or so were these springs where you would connect the electric match. It had some sort of computer driven way to fire to music. Does anyone remember the name of that system? I always thought it looked like yellow rain gutters. LOL
