The AT&T 3B2/500 was permanently retired in 1998 and SDF moved from System V3.2.3 UNIX to Slackware Linux on i386. In the left hand upper shelf, you can see two USR Sporster 33.6kbps modems, the 3COM NT1/TA ISDN modem and the Fujitec/Adtran DSL (1.5mbps/768kbps). On the lower shelf is a UPS, an ethernet switch and two power strips. On the right hand side is the host “sdf” in the taller cabinet with the Exabyte drive and “sdf-2” (later renamed “otaku”) in the shorter case. These systems are likely Intel Pentium MMX 233MHz which came from a failed attempt to start a “Cyber Cafe” in Dallas Texas. NetBSD 1.2 was attempted to run on this setup, as well as GNU Hurd (believe it or not).
