When I was a kid, I use to go to the Lawrence Livermore Science Lab and go to their public computer room where they had dozens of paper teletypes for the public to use to play with BASIC.
I believe you mean the
Lawrence Hall of Science (LHS) in the Berkeley Hills above the University of California at Berkeley, not the Lawrence Livermore National Laboratory (LLNL) out in Livermore, CA. The former is a science education museum and did run a timeshared multi-user BASIC interpreter service in the 1970s & early 1980s on a Data General NOVA (and later Eclipse) minicomputer, with public terminals at LHS, and TTYs connected via leased line to quite a number of high schools in the San Francisco Bay Area - I know because I used that service myself at two different schools in the 1970s.
One of the popular computer games available to play on that system was
Trek73. The exterior of LHS was used as a location shot for the dystopian 1970 movie,
Colossus: The Forbin Project.
