Summary
[edit]DescriptionAbacus at Soda Hall, UC Berkeley.jpg |
English: A six-foot tall wooden abacus featured in the lobby of Soda Hall, the computer science building at University of California, Berkeley. The sign above it reads "USE DURING POWER FAILURE OR IF YOUR COMPUTER CRASHES / IF ABACUS SYSTEM DOES NOT BOOT PROPERLY, CHECK BATTERY!" The sign has since been removed. I'm very fond of this abacus and it's liable to show up again.
