    Can you summarize the replies to me/the net?

    I hope not, I was able to sample audio from the tape recorder jack
    on my Apple II in 1979. Check out the Sound Manager chapter of
    Inside Macintosh, volume VI, the section on recording sounds directly
    from a device - this'll get you crummy 8-bit sampling, which may not
    be good enough for your needs. Of course, make sure you have a Mac 
    with a sound input jack first!

    There's also a large selection of A/D boards you can add which do
    all sorts of things. Try National Instruments, or any music nerd

I still urgently need far more information, especially re. A/D boards.

Unfortunately "music nerd" magazines don't seem to get as far as my
area, nor do local Mac dealers comprehend my query.  So I am still not
much the wiser. 

I had imagined that user-friendly Mac A/D boards existed but it is
certainly proving very difficult to track down anything useful whatever.

Perhaps around LA and Boston there are many outlets for such things, it
would be a very useful service were Apple to be able to give people in
other areas (especially overseas) some real pointers - it is not
realistic to phone random Boston dealers (on international calls at
one's private expense).

I had plans to hack up a ECG display for a friend, but it looks as
though this could biting off too much (at least in MCL). Maybe it is
more practical in NeXTstep.
