Yeah it was definitely something geared towards graphics professionals...just found an old magazine ad for it, looks like it had a Trinitron tube and ran for $2700 at the time. It weighed an absolute ton. I certainly enjoyed the screen real estate for playing Sim City when my parents weren't working!

Also in googling for it I found it had been featured in Jurassic Park: https://productplacementblog.com/movies/supermatch-20-t-moni...
