Hello all! My brother and I wish to extract raw sound data from the MTH Proto-Sound 1 boards. In order to do that, we need to identify what chips are on the board and what purpose they serve. We recently came across a thread that partially answers our questions https://ogrforum.ogaugerr.com/...-ps1-soundboard-work, although the actual type of chip the PROM is was never identified, which is what we're most interested in finding out. If anyone has some insight or can send photos, please share! We are also looking to buy a Proto-Sound 1 board, whether it functions or not. If you're willing to send us one, again, please let us know!
We thank you all for taking to time to read this and considering to contribute to this project!
