When I was a graduate student, I used to collect a variety of older RISC workstations to play with all of the different exotic flavors of Unix that preceded Linux. I downsized my collection substantially when I moved to California, so this page will be mostly a memory of what used to be.

For the time being, here is an old photo of a few of my Sun Blade workstations with my girl Anna enjoying them.

Various Sun workstations

I had a steady supply of Sun and Silicon Graphics hardware at the time, and I cut my teeth on Solaris and IRIX as a result.


Of less interest are my collection of single-board computers. I put them here mostly so I remember what I've got scattered around.
