  DSD 880 Control Panel by Bill Degnan - 06/23/2010 14:54
Pictured is a control panel for a DSD 880 which is (?) a plug-compatible RX02/RL02 emulator for PDP8/PDP11 minicomputers. I think that the associated PDP 11 also ran a "FuzzBall" router controller designed by Professor Dave Mills of the University of Delaware. The Fuzzball was the router selected for use in launching the National Science Foundation Network (NSFNET) in 1985, the direct ancestor to the commercial Internet (WWW).

In the early 1980's MILNET was spun-off of ARPANET. Soon afterwords the National Science Foundation launched the NSFNET service on the now non-classified ARPANET system, in 1984-85. NSFNET used the ARPANET TCP/IP standard.

NSFNET went commercial in the early 1990's ushering in the modern era of the World Wide Web.

Bill,

The panel shown is, as labeled, the control panel for a DSD 880 which is a plug-compatible RX02/RL02 emulator for PDP8/PDP11 minicomputers. A very cool device but not a router.

Jack,
I will check with the source to get more details. Perhaps this controller was from the PDP 11 system that did the routing, but as there are no controls that one would associate with actual routing itself, no indicator or data transmission, etc.

Here is a link to some pictures of Digital/VAX network equipment at University of Delaware from the later 80's. The "not pictured" paragraph at the bottom of the page may describe the system(s) that this DSD 880 came from.
