Digital out from a deck with it is a way to do it which is very good. The best is to kiss up to someone with an RH1. This MD player can xfer any non-DRM MD as an upload, even legacy. The xfer is done digitally and way faster than real-time, and that's what is sweet: it is so much faster.
Minidisco.org is where the MD heads hang out. Try there.
How many MD's are you talking about?
