I bought it as part of a working A2000 set up with Picasso-II, Fusion-Forty and HC+8.
The guy I got it from used it for all manner of things - including generating 3D animations of the Isle of Man TT course for video productions.
I tried to get the machine working with a CV64-3D which didn't work, as it needs KS3.1.
I tried to install KS3.1 (which the guy had bought but never got working). The chips were fine, but the accelerator wasn't recognised.
After a lot of investigation, it turns out that you need to update the ROMs on the board - something I didn't have the time or inclination to do, as the machine was bought as a spare; my first "big box" Amiga.
Nobody seemed interested in buying the whole kit-and-kaboodle together, so I decided to split the boards out - there was a lot of demand for the Picasso-II, so that was shipped off to Canada, and the motherboard was sent to the US.
I'm now left with the shell, the two cards which are advertised, a modulator, and a nest of leads ;-)
The accelerator worked perfectly under 2.0, but it didn't give me the "Amiga experience" to which I'd become accustomed during the daily use of my PPC A1200...
