The page is very specific that it only works with an MZ-RH1 HiMD Walkman. Assuming that information is accurate, looks like it could be hard for me to acquire such a machine. I will ask around though, as it could be the optimal solution. I'll re-visit my current code when I have time again, but if my suspicion is correct then I may need a different device to play from; looking for it to behave like my CD player does, in terms of stopping or changing stream between tracks.
