While preliminary data analysis was conducted in 2002, a large portion of the data was never analyzed. This data, now 20 years old, could contain valuable information about the cosmological lithium problem. The original hardware as well as the original data analysis software are no longer available. Using the original log books new software has been written that allows for the reading of this data so that it may be fully analyzed. The work on this project involved considerable time studying the raw data in hexadecimal format to look for patterns and structures that could be used to interpret the data. Approximately 800 total lines of code, written in Python, were used to be able to read the data and begin preliminary analysis on it. 1d histograms for individual detectors have been constructed, and the normalization constants for the detector energies have been recovered.
