I didnt find it directly, but a fiend who works where a basketball team has its practises found an Amiga 4000, the Video Toaster 4000 version, in the garbage and grabbed it knowing I was into Amigas. I got it home and opened it up. Video Toaster and the A/B Roll system were installed. Two hard drives. an 030 Amiga. The power supply fan had failed and the machine overheated so they threw it out. Only damage was the power connectors on the hard drives were ruined. I held them on the drives with my finger while I copied all the data to a new drive, fixed the fan, and it's been fine ever since.
I know it was the basketball teams because there were images of them practising saved on the drive from the framestore.
