Who was producing a PDP-10 in 2004? I'd love to know more about this.

XKL's TOAD-2 is/was based on a single chip PDP-10.

The hardware is used as a router, but supposedly if you ask it very nicely you can get it to run TOPS-20.

Living Computer Museum had two XKL-2 running TOPS-20.

Yup, the XKL TOAD ("Ten On A Desk") and TOAD-2.

At the time of TOAD-1, there were also still machines built based on SC design, for effectively singular consumer - Compuserve.
