Reply to "Willing to buy MTH Proto-Sound 1 Boards (Working or Dead) + Identifying Board Components"

Thank you so much for the information @tansqrx! The thing I'd probably want to do as well is extract the raw digital audio data from the locomotives. Unfortunately, the PROM chip that contains the sounds is programmed. If we read from the chip, the audio data would be in a proprietary format which would be very difficult to convert to MP3. You'd end up having to find pointers to the sound data in a hex editor and go from there.
