I started working for SRI ( in Don Nielson's group) at the end of September/beginning of October 1983. Very soon I got a Sun 100 in my office using Ethernet. I don't think we had more than 9 as they were named for the planets. My host name was Venus. I don't remember having any other computer at SRI before that one showed up.

although I don't think there was very much use until well into 1984 (using pirated IPv4 space). My group had to renumber a lot of hosts a few years later in order to join the Internet, by which time TCP/IP usage on-site was substantial. This was over (yellow) Ethernet, plus our home-made bridges via the 2 Mbps CERNET site-wide network. I don't recall exactly when we started installing "thin" Ethernet.
