1992 Tantrum mountain bike help needed

[Swingmodern]

Hello,
I recently purchased this bike but haven't been able to find out anything about it online. Hoping some of the knowledgeable folks here might have some insight.

It was designed by Jonathon S....; can't read the rest of the last name. Has an AMP rear suspension. TT welded on the BB. Decals designed by Josh Jacobson. Cool logo graphics.

Thanks!

Only online reference I found was a Tantrum Company, founded in 2015, to promote a new rear suspension design.
The founder and designer was named Brian Berthold - Your bike looks a good deal older.
I also saw that Raleigh made a women's bike called a "Tantrum" - Also obviously NOT your bike.
