Seems to work very well on it. My NetBSD systems are a IIci, a Q605, a G4 mini, an RPi and the Jornada (I also have it on a card for my MIPS WorkPad but I usually run it in WinCE), so I have a long history with it. In general I like the BSDs more as servers, and the J690 is indeed just that, a microserver I bring along for demonstrations.
