It's a trickier one to find information on! Apparently it was made by Control Data Corp in 1979+. I'll edit this comment if I find more... I'm curious too!

Edit: It's pretty hard to find anything about it! Apparently the University of Georgia had one too, but I'm giving up now and getting back to work :)

Edit 2: Apparently it was IBM (360?) compatible: https://it.unt.edu/sites/default/files/benchmarks-01-1980.pd...
