Old computers have been a long time interest for me by now. It started out with a computer society called UFH, where we had a PDP-11/40.

Later I got myself a pair of PDP-8/A systems, which I named BRUTUS and CAESAR. I still have both of them around, both functional. Along the way, however, I got myself another five PDP-8 systems. Two have found their way to other owners since then, so I now have five PDP-8 systems. One PDP-8/M, one PDP-8/F, one PDP-8/E and the two PDP-8/A systems. The 8/E system is my "big" machine, where I have all kind of hardware attached.

When I started studying at Uppsala University, they had two DEC-2060 systems, which I enjoyed playing on. There was also a computer club there, called Update. Update owned a PDP-8/I system.

I got involved since Update received a PDP-11/34A system, and I was the only person around who knew how to play with it. So I started playing with PDP-11s again, and soon Update's collection grew, adding a couple of -11/70s along the way. Those machine are my personal favourites. Got to love big iron. :-)
If you need help with PDP-11s, or RSX, read this page.

The third line of computers are (of course) VAXen. At Update, we managed to get our hands on two VAX8650 machines. If the PDP-11/70 is the ultimate PDP-11, then the VAX8650 comes pretty close to the ultimate VAX.. The 8650s were evetually replaced by three VAX-6440, but in the end it turns out the 8650s have outlived them. As I write this, one 8650 is back in the computer room, and all 6440s have been rolled out, since they have all broken down.

I've collected information on several different Digital computers over the years, and have made separate pages about them:
