I am planning to build an interface to program a Sony Diskman CD player
from a computer.  The idea is to store track sequences for various CD's
on disk and download them to the player.  The player (model DP-250, probably
sold under some other name in the States) has an input jack that looks like
a stereo minijack, labeled `remote'.  Does anyone know the pin assignments,
electrical characteristics and the protocol for the interface?  Information
on interfaces of other models could be useful, since many share the same logic.
Post or mail replies, I will summarize.  When I finish I will post schematics 
and software.
