We stock the Supply Cabinet and some nearby storage drawers by 485 and elsewhere (noted below) with useful supplies.
If you find we have run out of some of these supplies or if there is something you'd like us to keep in stock, let us know at radlab-staff@cs.berkeley.edu.
In the drawer labeled “keyboards” by 477, we keep a collection of keyboards and mice, some used, some new. If you just want a random keyboard, that's the place to go. If you want something specific, send email to radlab-staff@cs.berkeley.edu. We also keep a small stash of power strips, though by now most desks should have one already.
