Rainbow at Myrtle Beach Pavilion?

My family used to go to Myrtle Beach nearly every year, and now all of those years are starting to blur together. Does anyone remember:

- when the (Huss) Rainbow there opened?

- what used to be in that spot before it? (It's squeezed in on the corner, so maybe there wasn't anything there. I really don't remember.)

Looks like the Little Eagle coaster showed up in '86, and I was thinking the Rainbow showed up around the same time or a little before, but I really don't remember that well.

Thanks ahead of time!
