Low ceilings and other impediments (includes floods)

Floods Our computer room was on the 10th floor of an office building and the drain for the water cooled air handler dumped into a sink in the hall next to the elevator. The cleaning crew left a mop in the sink and it clogged up. We flooded the entire area below our raised computer floor. Amazingly the PDP 11/70 and RP04 kept on running, we noticed the problem because of the humidity in the room when we came in. Nothing like mold covered cables in raceways. We tried wicking the water out and blowing hot air under the floor, the mold really liked the hot air. Being on the 10th floor surrounded by low buildings we used to estimate how many mag tapes we could braid together to escape from a fire, we knew the ladder trucks couldn't reach us. We also estimated the disk safe with our backup disks would probably end up on some lower floor. Mike mmcfadden(a)cmh.edu
