As of May 20th (the start of the Summer 2013 semester), the Chemistry B201 Computer lab will be relocated to Yates 412. We will begin moving the computer hardware on the 20th, so it may be a few days before the lab is at full operation in terms of capacity. Yates 412 will adopt the same swipe card access as B201 did, meaning that all Chemistry affiliated students will have access 24 hours a day.
Oh, and Yates 412 has WINDOWS (the kind you can look out of, not the Operating System).
