A couple of questions for the NeXT gurus that read this group.

1.  Is the mouse port connector documented in any of the manuals?
     (The one on the back of he keyboard.)

2.  I am able to get a mouseDown event.  Is it possible to distinguish 
    between the left button, the right button, and a chord of both buttons?
    Also, can I get an event for both the button press and the button
    release?

3.  Does the codec microphone go through the DSP chip?  Any info on the
    Freq. response of the microphone signal (after the microphone).  Does
    the signal go through a Low Pass filter with a cutoff of ~4kHz?

4.  Is it possible to listen to the signal that is being recorded (At the
    same time?)

5.  Is 32KB the only DSP Memory Expansion available?
    (Most of the 56000 manuals say that the 56000 is a 10 Mips chip.  I have
    also seen estimates that the 68040 is a 15 Mips chip.)  How does the
    56000 compare to the 68040?  I do realize that the DSP chip is optimized
    for certain operations...

Couple of comments:
1.  Improv looks pretty nice.  However, it would be nice if one could give 
    a block of cells as the labels for the x axis.

2.  NeXT must repackage the 2.88 Meg disks that they sell in a 5-pack.  They
    come in a little cardboard box that has the NeXT lego on it.  So, if you
    have a NeXT T-shirt, a NeXT mug, you have to get a 5-pack of disks.
    (Of course, if we were really loyal, we would go get NeXT tattoos like the
    Harley Davidson loyalist do :-)
