As of 2015, one was still running: https://www.popularmechanics.com/technology/infrastructure/a...
Haven't powered it up for a few years, and the internal floppy drive, which was an upgrade to a PC format (and I can't remember the make or model of the upgrade), is busted.
Still, I have the AmigaOS 3.9 CD, I might get the old girl running again sometime.
