AFAIK picoBSD is just a standard FreeBSD kernel with a specific
set of hardware support and a very specifically targetted small

If you _really_ want to put a more modern OS onto the box
you could start with ELKS (The Embeddable Linux Kernel Subset) at

Personally, I'd leave 2.11 on the PDP and concentrate on NetBSD
