I've done it.  I did have a BBC B Welcome CD image somewhere, each
program was a seperate track on the CD.

I wrote a prog in BBC Basic-86 which generates a windows .wav file
from a file, which could then be recorded to CD as normal.  I used
it to transfer downloaded software from my PC to a Beeb when I didn't
have a cable.

The sample rate of the wav file was a bit low (otherwise I got massive
files) and it did sometimes get a bit distorted.

I also tried something that would read a sampled wav file and convert
it back to data.

I was getting close to motor control by hacking apart a CD player and
hooking the motor relay to the pause button (would have to be rising
and falling edge triggered though)

If anyone's interested I'll see if I can find any of it.
