If I remember correctly the Apple PowerMac G4 was touted as the first Consumer system capable of GFLOPS.  The G4/450 when released, was an amazing system, but it was very quickly left in the dust.

Floating Point Systems was a few miles away from where I live.  A couple weeks ago, we drove by there, and I noticed that at least the main office building is still there.  I used to work with a couple of people that had worked there.  Years ago I found one of the Array Processors at Wacky Willies, I didn’t get it, but I did get the PDP-11/44 manual that was with it.  I think I might have a VAX tape around here for one of their Array Processors.
