OpenBSD is the only OS ever to run on my Tadpole laptops without any modification necessary. Even Solaris 8 and 10 needed special software to run on them. OpenBSD works right out of the box.
SPARC was where Theo cut his teeth in the netbsd years, anecdotal but I think it’s his favourite pet so you’d imagine it’ll be well supported on his os
>The other architectures that OpenBSD supports have benefited because some kinds of bugs are exposed more often by the 64-bit big endian nature of UltraSPARC.
