hi koen
that's exactly what i started about 10 years ago.
before I started to design a robot for about 1000 cd's, pioneer =
presented it's first 100cd player. so I decided not to build the robot =
myself and bought a 100cd player farm.
as an intermediate solution, I also bought their controller, which was =
able to control 3 of these players. so I could at least play about half =
of my cd's, until my own controller was finished.
unfortunately, the project never got an end, and some of the players =
have never been used...
when mp3 got available, I built a dos based mp3 jukebox, controlling =
some scsi cd changers, and I copied my music cds to mp3 cds (reducing =
the whole thing to 60 cds).
the result wasn't very satisfying, as these cd changers have been very =
slow when searching, and they often hung when they had problems to load =
or read a cd.
so then, when harddisks got cheaper, I copied the whole thing to a hd, =
and the result is a win95 based mp3 server, which is so easy handle, =
that anybody is able to use it...
...and the best of it:
this thing has an Ethernet i/f, allowing me to have some more 'diskless' =
players in other rooms, and anyone is able to listen to different music, =
getting all data from the same harddisk.
so I don't see a single reason to build a cd changer anymore.
