During the late winter 1996 observing season we deployed a prototype high speed fiber fed photometer at the WIYN observatory. The photometer consisted of 4 channels; two channels of 1000 mu core fiber optic, and two channels of 400 mu core fiber optic. The two core sizes corresponded to ~ 3('') .8 and 9('') .6 apertures respectively for the 400 mu and 1000 mu fiber optics at the focal plane of the WIYN telescope. The primary detectors were Hamamatsu R5600U photomultiplier tubes with 3/8 inch bialkali photocathodes. The system was designed to provide sampling frequencies > 1 kHz. The instrument was designed to smoothly integrate into the HYDRA multi-object spectrograph. The goal of the prototype system was proof of concept. The instrumentation will be described and the results from a 2 night observing run will be presented.
