Here is the old SDF AT&T 3B2/500 UNIX System, which was decommissioned in 1998, making its debut
with the Qwest Museum of Communications at the Duwamish Central Office in Seattle WA on January 20th, 2009.
Visitors can access the system via Model 33, Model 35 and Model 37 Teletypes @ 110 and 150 baud,
Model 43 @ 1200 bps and 4410 video terminals at 9600 bps. 8 dialup lines are provided by a working
Western Electric #5 Cross Bar office switch. There is a small UUCP network using two Telebit TB+
PEP modems which were used by SDF to communicate with Southern Methodist University,
Adaptec Corporation, Texas Instruments and others from 1990 up until 1998.
