1. A system for allowing simplified access to raw vibration data collected by a vibration monitoring computer associated with an aircraft engine, when the vibration monitoring computer is mounted on the engine, comprising:
means for capturing raw vibration waveforms;
means for digitizing the captured raw vibration waveforms to capture analog waveform data;
means for providing expanded memory for the vibration monitoring computer; and
means for storing the digitized waveforms for subsequent retrieval.
